Teichmann, J. Tolkiehn, K. Weger, J. Wiggins, K. Wrona, M. Yakopov, C. Youngman XFEL. EU, Hamburg, Germany
	The European XFEL is a 3.4km long X-ray Free Electron Laser in the final construction and commissioning phase in Hamburg. It will produce 27000 bunches per second at 17.5GeV. Early 2015 a first electron beam was produced in the RF-photo-injector and the commissioning of consecutive sections is following during this and next year. The huge number and variety of devices for the accelerator, beam line, experiment, cryogenic and facility systems pose a challenging control task. Multiple systems, including industrial solutions, must be interfaced to each other. The high number of bunches requires a tight time synchronization (down to picoseconds) and high performance data acquisition systems. Fast feedbacks from front-ends, the DAQs and online analysis system with a seamless integration of controls are essential for the accelerator and the initially 6 experimental end stations. It turns out that the European XFEL will be the first installation exceeding 2500 FPGA components in the MicroTCA form factor and will run one of the largest PROFIBUS networks. Many subsystem prototypes are already successfully in operation. An overview and status of the XFEL control system will be given.

Yoshii Mitsubishi Electric System & Service Co., Ltd, Tsukuba, Japan K. Asano, M. Hirose KIS, Ibaraki, Japan Y. Iitsuka, N. Yoshifuji EJIT, Hitachi, Ibaraki, Japan
	SuperKEKB is the upgrade of KEKB, the asymmetric energy electron-positron collider for the B-factory experiment in Japan. It aims at the 40-times higher luminosity than the world record by KEKB. The KEKB control system has been built based on EPICS at the equipment layer and scripting languages at the operation layer. The SuperKEKB control system continues to employ these frameworks while we implement new features for the successful operation at such a high luminosity. As the commissioning of the SuperKEKB main storage rings is scheduled to start in 2016, the construction of the control system is now in the final phase. We have upgraded and reinforced the network system, server computers and operator consoles. Most of the VME-based IOCs (I/O Controllers), which has been widely used in KEKB, are upgraded while the PLC-based IOCs are also widely introduced. The new timing system has been developed in order to handle the complicated injection scheme of the SuperKEKB accelerator complex efficiently. The new beam abort trigger system and the new beam gate control system have been developed, and so on. The construction status of the SuperKEKB accelerator control system will be presented.

MOC3O01	Comprehensive Fill Pattern Control Engine: Key to Top-Up Operation Quality	injection, operation, experiment, radiation	18
	T. Birke, F. Falkenstern, R. Müller, A. Schälicke HZB, Berlin, Germany
	Funding: Work supported by BMBF and Land Berlin. At the light source BESSY II numerous experiments as well as machine development studies benefit from a very flexible and stable fill pattern: standard operation mode comprises a multibunch train for the average users, a purity controlled high current camshaft bunch in a variable length ion clearing gap for pump/probe experiments and a mechanical pulse picking chopper, three high current bunches for femto second slicing opposite to the gap and a specific bunch close to the end of the ion clearing gap for resonant excitation pulse picking. The fill pattern generator and control software is based on a state machine. It controls the full chain from gun timing, linac pulse trains, injection and extraction elements as well as next shot predictions allowing triggering the next DAQ cycle. Architecture and interplay of the software components as well as implemented functionality with respect to hardware control, performance surveillance and reasoning of next actions, radiation protection requirements are described.

MOC3O02	PID_TUNE: A PID Autotuning Software Tool on UNICOS CPC	framework, cryogenics, PLC, operation	22
	E. Blanco Vinuela, B. Bradu, R. Marti Martinez CERN, Geneva, Switzerland R. Mazaeda, L. de Frutos, C. de Prada University of Valladolid, Valladolid, Spain
	PID (Proportional, integral and derivative) is the most used feedback control algorithm in the process control industry. Despite its age, its simplicity in terms of deployment and its efficiency on most of industrial processes allow this technique to still have a bright future. One of the biggest challenges in using PID control is to find its parameters, the so-called tuning of the controller. This may be a complex problem as it mostly depends on the dynamics of the process being controlled. In this paper we propose a tool that is able to provide the engineers a set of PID parameters in an automated way. Several auto-tuning methods, both in open and close loop, are selectable and others can be added as the tool is designed to be flexible. The tool is fully integrated in the UNICOS framework and can be used to tune multiple controllers at the same time.

MOC3O04	System Identification and Robust Control for the LNLS UVX Fast Orbit Feedback	feedback, network, vacuum, power-supply	30
	D.O. Tavares LNLS, Campinas, Brazil D.R. Grossi Sao Paulo University, São Carlos Campus, São Carlos, Brazil
	This paper describes the optimization work carried out to improve the performance of the LNLS UVX fast orbit feedback system. Black-box system identification techniques were applied to model the dynamic behavior of BPM electronics, orbit correctors, communication networks and vacuum chamber eddy currents. Due to the heterogeneity on the dynamic responses among several units of those subsystems, as well as variations on the static response matrix due to accelerator optics changes during operation, robust control techniques were employed to achieve appropriate closed-loop performance and robustness.

MOC3O07	Low Level RF Control Implementation and Simultaneous Operation of Two FEL Undulator Beamlines at FLASH	operation, LLRF, laser, undulator	42
	V. Ayvazyan, S. Ackermann, J. Branlard, B. Faatz, M.K. Grecki, O. Hensler, S. Pfeiffer, H. Schlarb, Ch. Schmidt, M. Scholz, S. Schreiber DESY, Hamburg, Germany A. Piotrowski FastLogic Sp. z o.o., Łódź, Poland
	The Free-Electron Laser in Hamburg (FLASH) is a user facility delivering femtosecond short radiation pulses in the wavelength range between 4.2 and 45 nm using the SASE principle. The tests performed in the last few years have shown that two FLASH undulator beamlines can deliver FEL radiation simultaneously to users with a large variety of parameters such as radiation wavelength, pulse duration, intra-bunch spacing etc. FLASH has two injector lasers on the cathode of the gun to deliver different bunch trains with different charges, needed for different bunch lengths. Because the compression settings depend on the charge of bunches the low level RF system needs to be able to supply different compression for both beamlines. The functionality of the controller has been extended to provide intra-pulse amplitude and phase changes while maintaining the RF field amplitude and the phase stability requirements. The RF parameter adjustment and tuning for RF gun and accelerating modules can be done independently for both laser systems. Having different amplitudes and phases within the RF pulse in several RF stations simultaneous lasing of both systems has been demonstrated.

MOD3O02	Continuous Delivery at SOLEIL	software, operation, monitoring, Linux	51
	G. Abeillé, A. Buteau, X. Elattaoui, S. Lê SOLEIL, Gif-sur-Yvette, France G. Boissinot ZENIKA, Paris, France
	IT Department of Synchrotron SOLEIL* is structured along of a team of software developers responsible for the development and maintenance of all software from hardware controls up to supervision applications. With a very heterogonous environment such as, several software languages, strongly coupled components and an increasing number of releases, it has become mandatory to standardize the entire development process through a 'Continuous Delivery approach'; making it easy to release and deploy on time at any time. We achieved our objectives by building up a Continuous Delivery system around two aspects, Deployment Pipeline and DevOps. A deployment pipeline is achievable by extensively automating all stages of the delivery process (the continuous integration of software, the binaries build and the integration tests). Another key point of Continuous Delivery is also a close collaboration between software developers and system administrators, often known as the DevOps movement. This paper details the feedbacks on this Continuous Delivery approach has been adopted, modifying daily development team life and give an overview of the future steps. http://www.synchrotron-soleil.fr/ http://martinfowler.com/bliki/DeploymentPipeline.html *https://sdarchitect.wordpress.com/2012/07/24/understanding-devops-part-1-defining-devops/

Reed, J. Rouse, R.J. Sanchez, M.J. Shaw, E.A. Stout, S. Weaver, E.F. Wilson LLNL, Livermore, California, USA
	Funding: This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. The National Ignition Facility (NIF) is the world's largest and most energetic laser experimental facility with 192 beams capable of delivering 1.8 megajoules of 500-terawatt ultraviolet laser energy. The energy, temperatures and pressures capable of being generated allow scientists the ability to generate conditions similar to the center of the sun and explore physics of planetary interiors, supernovae, black holes and thermonuclear burn. NIF has transitioned to a 24x7 operational facility and in the past year significant focus has been placed on increasing the volume of experimental shots capable of being conducted so as to satisfy the demand from the wide range of user groups. The goal for the current fiscal year is a shot rate of 300 (> 50% increase over the previous year), increasing to a sustainable rate of 400 the year after. The primary focus areas to achieve these increases are; making more shot time available, improvements in experiment scheduling, and reducing the duration of a shot cycle. This paper will discuss the control system improvements implemented and planned to reduce the shot cycle duration and the systematic approaches taken to identify and prioritize them.

MOD3O04	Introducing the SCRUM Framework as Part of the Product Development Strategy for the ALBA Control System	software, framework, operation, synchrotron	60
	G. Cuní, F. Becheri, D. Fernández-Carreiras, Z. Reszela, S. Rubio-Manrique ALBA-CELLS Synchrotron, Cerdanyola del Vallès, Spain
	At Alba, the Controls Section provides the software that is needed to operate the accelerators, the beamlines and the peripheral laboratories. It covers a wide range of areas or subsystems like vacuum, motion, data acquisition and analysis, graphical interfaces, or archiving. Since the installation and commissioning phases, we have been producing the software solutions mostly in single-developer projects based on the personal criteria. This organization scheme allowed each control engineer to gain the expertise in particular areas by being the unit contact responsible to develop and deliver products. In order to enrich the designs and improve the quality of solutions we have grouped the engineers in teams. The hierarchy of the product backlogs, represents the desired features and the known defects in a transparent way. Instead of planning the whole project upfront, we try to design the products incrementally and develop them in short iterations mitigating the risk of not satisfying the emerging user requirements. This paper describes the introduction of the Scrum framework as the product development strategy in a service oriented organization like the Computing Division at Alba. D.

MOD3O05	Use of Automation in Commissioning Process of the Undulators of the European X-Ray Free Electron Laser	undulator, interface, PLC, Ethernet	64
	S. Karabekyan, J. Pflüger XFEL. EU, Hamburg, Germany L. Lin, Y.T. Liu USTC/NSRL, Hefei, Anhui, People's Republic of China W. Wang Hisense Co. Ltd., Qingdao, People's Republic of China
	For operation of the three undulator systems of the European XFEL, a total of 91 undulators are needed and have been produced. For production, magnetic measurements, tuning and commissioning of these devices only two years were foreseen by the project schedule. For these purposes, automated and optimized procedures were needed to accomplish a number of workflows, time-consuming adjustments and commissioning tasks. We created several automation programs which allowed us to reduce the time spent on the commissioning of the control system by an order of magnitude.

MOD3O06	Interface Management for SKA Telescope Manager	interface, TANGO, operation, monitoring	68
	P.S. Swart, G.M. le Roux SKA South Africa, National Research Foundation of South Africa, Cape Town, South Africa A. Marassi, R. Smareglia INAF-OAT, Trieste, Italy S. Roy Chaudhuri Tata Research Development and Design Centre, Pune, India S. Vrcic NRC-Herzberg, Penticton, BC, Canada
	The Square Kilometre Array (SKA) project is currently in the Pre-construction Phase. During this phase, the telescope subsystems are being designed. The Telescope Manager (TM) is a supervisory control and monitoring subsystem in each of the two radio telescopes of the SKA (SKA1-Low and SKA1-Mid). The TM interfaces with a number of diverse telescope subsystems. Interaction between TM and these subsystems is a major source of requirements for the TM. Careful management of TM external interfaces is therefore important. This discussion is a case study of TM interface management. Firstly, how system architectural design aspects like separation of concerns in the control hierarchy reduce telescope complexity with regards to interfaces is discussed. Secondly, the standardisation approach for monitoring and control interfaces to facilitate early elicitation of interface requirements for the TM, and to manage the diversity of interfacing subsystems is discussed. Thirdly, the relations between interface definition and requirements analysis activities, using SysML representations as an example is discussed.

	This paper report about a control system for a dedicated accelerator for SACLA wide-band beam line (BL1), requirements, construction strategies, and present status. At the upgrade plan of SACLA BL1, it was decided to move SCSS test accelerator, which operated from 2005 to 2013, to the upstream of the BL1 in the undulator hall. The control system of the accelerator had to be operated seamlessly with SACLA, to reuse old components as much as possible, and to avoid stopping SACLA user experiments during the start up. The system was constructed with MADOCA which is already used at SACLA. In the control components, VME optical DIO cards and chassis for magnet power supplies were reused after cleaning and checking that there was no degradation of quality. The RF conditioning of the accelerator was started in in October 2014, while SACLA user experiments were going on. A data collection system was prepared, myCC, having a MADOCA compatible interface and an independent database from SACLA. It enabled efficient start up and after enough debugging, the data collection was successfully merged to SACLA in January 2015. Beam commissioning of the accelerator is planned for autumn 2015.

	C. Kim, S.Y. Baek, H.-S. Kang, J.H. Kim, K.W. Kim, I.S. Ko, G. Mun, B.R. Park PAL, Pohang, Kyungbuk, Republic of Korea
	Pohang accelerator laboratory (PAL) started an x-ray free electron laser project (PAL-XFEL) in 2011. In the PAL-XFEL, an electron beam with 200 pC will be generated from a photocathode RF gun and will be accelerated to 10 GeV by using a linear accelerator. The electron beam will pass through undulator section to produce hard x-ray radiation. In 2015, we will finish the installation and will start a commissioning of the PAL-XFEL. In this paper, we introduce the PAL-XFEL and explain present status of it. Details of the control system will be described including a network system, a timing system, hardware control systems and a machine interlock system.

MOM311	ALMA Release Management: A Practical Approach	software, hardware, site, operation	94
	R. Soto, N. Saez, T.C. Shen ALMA Observatory, Santiago, Chile J.P.A. Ibsen ESO, Santiago, Chile
	The ALMA software is a large collection of modules, which implements the functionality needed for the observatory day-to-day operations. The main ALMA software components include: array/antenna control/correlator, submission/processing of science proposals, telescope calibration and data archiving. The implementation of new features and improvements for every software subsystem must be coordinated by considering developers schedule, observatory milestones and testing resources available to verify new software. This paper describes the software delivery process adopted by ALMA since the construction phase and its evolution until these days. It also presents the acceptance procedure implemented by the observatory for validating the software used for science operations. Main roles of the software delivery and acceptance processes are mentioned on this paper by including their responsibility at the different development and testing phases. Finally, some ideas are presented about how the model should change in the near future by considering the operational reality of ALMA Observatory.

MOPGF001	Use Interrupt Driven Mode to Redesign an IOC for Digital Power Supply at SSC-LINAC	power-supply, linac, Ethernet, EPICS	98
	S. An, K. Gu, X.J. Liu, J.Q. Wu, W. Zhang IMP/CAS, Lanzhou, People's Republic of China
	SSC-LINAC control system is based on EPICS architecture. The sub control system of digital power supplies is a kind of IOC send and receive custom command via Ethernet and TCP/IP protocol. The old IOC is designed to use period scan mode IOC, and there are so many digital power supplies, that we can't make sure every connect condition of digital power supply is fine. IOC must wait a long time if one of them can't connect correctly and other digital power supply's PV may also be blocked. An IOC that uses interrupt driven mode to avoid the shortcoming was designed. This will be described in this paper.

MOPGF002	Magnet Corrector Power Supply Controller for LCLS-I	interface, feedback, EPICS, power-supply	100
	S. Babel, B. Lam, K. Luchini, J.J. Olsen, T. Straumann, E. Williams, C. Yee SLAC, Menlo Park, California, USA
	The MCOR-12[Magnet Corrector] is a 16-channel modular architecture, precision magnet driver, capable of providing bipolar output currents in the range from 12A to +12A. A single, unregulated bulk power supply provides the main DC power for the entire crate. Currently the MCORs have a 1000ppm regulation on the B-field. The MCOR controller card upgrades, existing LCLS-I and future LCLS-II needed, controls for Magnet Corrector Power Supplies. The project shifts the existing functionality of the VME based DAC and SAM and an Allen Bradley PLC into a new slot-0 card residing in the MCOR chassis. Elimination of the VME crate and the PLC will free up rack space to be used in future. The new interface card has a long term stability of 100 ppm and monitors ground fault currents and various other interlocks for the MCOR power supplies. The controller can interface to EPICS Channel Access and Fast Feedback system at SLAC using two Gigabit Ethernet ports and has an FPGA based EVR for getting 'time stamps' from the Event Generator system at SLAC. The EPICS control system along with embedded diagnostic features will allow for enhanced remote control and monitoring of the power supplies. S. Babel, S.

MOPGF006	The Renovation of the CERN Controls Configuration Service	database, software, factory, GUI	103
	L. Burdzanowski, C. Roderick CERN, Geneva, Switzerland
	The Controls Configuration Service (CCS) is a key component in CERN's data driven accelerator Control System. Based around a central database, the service also provides a range of client APIs and user interfaces - enabling configuration of controls for CERN's accelerator complex. The service has existed for 35 years (29 based on Oracle DBMS). There has been substantial evolution of the CCS over time to cater for changing requirements and technology advances. Inevitably this has led to increases in CCS complexity and an accumulation of technical debt. These two aspects combined have a negative impact on the flexibility and maintainability of the CCS, leading to a potential bottleneck for Control System evolution. This paper describes on-going renovation efforts (started mid-2014) to tackle the aforementioned issues, whilst ensuring overall system stability. In particular, this paper covers architectural changes, the agile development process in place - bringing users close to the development cycle, and the deterministic approach used to treat technical debt. Collectively these efforts are leading towards a successful renovation of a core element of the Control System.

MOPGF014	LLRF Controls Upgrade for the LCLS XTCAV project at SLAC	LLRF, linac, software, klystron	110
	S. Condamoor, Y. Ding, P. Krejcik, H. Loos, T.J. Maxwell, J.J. Olsen SLAC, Menlo Park, California, USA
	Funding: This work was performed in support of the LCLS project at SLAC. Work supported by the U.S. Department of Energy under contract number DE-AC02-76SF00515. SLAC's Low Level Radio Frequency (LLRF) controls software for the S-Band deflecting structures needed to be upgraded significantly when a new X-Band transverse deflecting cavity (XTCAV) was installed downstream of the LCLS undulators in Spring 2013 to assist in FEL diagnostics such as characterizing the temporal profile of X-ray pulses that vary shot-to-shot. The unique location of the XTCAV in the beamline posed several challenges. A new design of the Modulator and Klystron control Support Unit (MKSU-II) for interlocking was added at the XTCAV controls station that required new software development. The timing setup was also different from the rest of the Linac. This paper outlines the LLRF controls layout for the XTCAV and discusses the manner in which the challenges were addressed. XTCAV has now become a successful tool for gathering data that enables reconstruction of X-ray FEL power profiles with greater resolution. SLAC Publication Number: SLAC-PUB-16414

MOPGF015	Fast Wire Scanner Upgrade for LCLS	real-time, emittance, interface, EPICS	114
	J.M. D'Ewart, M.L. Campell, P. Krejcik, H. Loos, K. Luchini SLAC, Menlo Park, California, USA
	Wire scanners are a main diagnostic tool for transverse beam size and emittance measurements at LCLS. The original SLAC wire scanners were not optimized for speed (taking minutes to scan), and can't perform at the desired level of position resolution necessary for measuring LCLS' small beam size. A new fast wire scanner, based on a dc linear servo motor, has been designed and installed in the LCLS. The new fast wire scanner has several advantages over the original wire scanner: scan times are reduced from minutes to seconds while minimizing wire vibrations. Rather than counting open-loop step pulses, the new fast wire scanner uses real time position capture for beam synchronous sampling of the wire position, enhancing beam profile accuracy.

MOPGF016	Improving the Compact Muon Solenoid Electromagnetic Calorimeter Control and Safety Systems for the Large Hadron Collider Run 2	detector, hardware, software, experiment	117
	D.R.S. Di Calafiori, G. Dissertori, L. Djambazov, O. Holme, W. Lustermann ETH, Zurich, Switzerland P. Adzic, P. Cirkovic, D. Jovanovic VINCA, Belgrade, Serbia S. Zelepoukine UW-Madison/PD, Madison, Wisconsin, USA
	Funding: Swiss National Science Foundation (SNSF); Ministry of Education, Science and Technological Development of Serbia The first long shutdown of the Large Hadron Collider (LS1, 2013-2015) provided an opportunity for significant upgrades of the detector control and safety systems of the CMS Electromagnetic Calorimeter. A thorough evaluation was undertaken, building upon experience acquired during several years of detector operations. Substantial improvements were made to the monitoring systems in order to extend readout ranges and provide improved monitoring precision and data reliability. Additional remotely controlled hardware devices and automatic software routines were implemented to optimize the detector recovery time in the case of failures. The safety system was prepared in order to guarantee full support for both commercial off-the-shelf and custom hardware components throughout the next accelerator running period. The software applications were modified to operate on redundant host servers, to fulfil new requirements of the experiment. User interface extensions were also added to provide a more complete overview of the control system. This paper summarises the motivation, implementation and validation of the major improvements made to the hardware and software components during the LS1 and the early data-taking period of LHC Run 2.

	The Detector and Run Control systems for the NA62 experiment, which started physics data-taking in Autumn of 2014, were designed, developed and deployed in collaboration between the Physics and Engineering Departments at CERN. Based on the commonly used control frameworks, UNICOS and JCOP, they were developed with scarce manpower while meeting the challenge of extreme agility, evolving requirements, as well as integration of new types of hardware. This paper presents, for the first time, the architecture of these systems and discusses the challenges and experience in developing and maintaining them during the first months of operation.

MOPGF021	Database Archiving System for Supervision Systems at CERN: a Successful Upgrade Story	database, operation, experiment, software	129
	P. Golonka, M. Gonzalez-Berges, J. Hofer, A. Voitier CERN, Geneva, Switzerland
	Almost 200 controls applications, in domains like LHC magnet protection, cryogenics and vacuum systems, cooling-and-ventilation or electrical network supervision, have been developed and are currently maintained by the CERN Industrial Controls Group in close collaboration with several equipment groups. The supervision layer of these systems is based on the same technologies as 400 other systems running in the LHC Experiments (e.g. WinCC Open Architecture, Oracle). During the last two-year LHC Long Shutdown 1, the 200 systems have been successfully migrated from a file-based archiver to a centralized infrastructure based on Oracle databases. This migration has homogenized the archiving chain for all CERN systems, and at the same time has presented a number of additional challenges. The paper presents the design, the necessary optimizations and the migration process that allowed us to meet unprecedented data-archiving rates (unachievable for the previously used system), and liaise with the existing long-term storage system (LHC LoggingDB) to assure data-continuity.

MOPGF022	SIS18 Upgrade: The FAIR Compliant Renovation of the Data Acquisition System for Particle Detectors	hardware, detector, software, operation	133
	R. Haseitl, H. Bräuning, T. Hoffmann, K. Lang, T. Milosic GSI, Darmstadt, Germany
	In preparation of FAIR, several well-established beam instrumentation systems of the GSI heavy-ion synchrotron SIS18 and its connected high-energy beam transfer lines (HEBT) have to be modernized. In this contribution, the data acquisition upgrade of particle detectors such as ion chambers and plastic scintillators is described. This covers the replacement of an outdated custom-built readout- and control hardware by modern FMC (FPGA mezzanine card) based I/O hardware, new multi-channel high voltage power supplies and a new data acquisition system (DAQ) for the VME based scalers. The latter will replace the old Kylix-based ABLASS software by LASSIE (Large Analog Signal and Scaling Information Environment) to fit into the new FAIR control system concept. LASSIE is based on FESA (Front End Software Architecture). FESA was originally developed by CERN and enhanced by GSI-specific modifications. Furthermore, the new particle detector DAQ will be able to take full advantage of the new FAIR timing system which is based on the White Rabbit protocol.

MOPGF023	Update of Power Supply Control System at the SAGA Light Source Storage Ring	storage-ring, PLC, target, power-supply	137
	Y. Iwasaki, T. Kaneyasu, S. Koda, Y. Takabayashi SAGA, Tosu, Japan
	The update of control system at the SAGA Light Source storage ring power supplies is in progress for improving the ramp-up speed (from 255 MeV to 1.4 GeV) and for easily changing the stored beam energy. By replacing the CPU unit of PLC used for control of the power supplies, the ramp-up time was reduced from 4 to 2 minutes in a test bench prepared for the upgrade system. Currently the allowable beam energy is restricted to some fixed values in the ramp-up operation due to the original specification of the PLC ladder program. To operate storage ring at an arbitrary energy, the algorism used in the PLC program has been improvement. Energy dependent measurements (betatron-tune, beam size, and beam half-lifetime) will be carried out by using the updated control system. The upper layer of the control system using the National Instrument LabVIEW and ActiveXCA was also reconstructed for flexible GUI.

MOPGF027	Real-Time EtherCAT Driver for EPICS and Embedded Linux at Paul Scherrer Institute (PSI)	EPICS, Linux, real-time, interface	153
	D. Maier-Manojlovic PSI, Villigen PSI, Switzerland
	EtherCAT bus and interface are widely used for external module and device control in accelerator environments at PSI, ranging from undulator communication, over basic I/O control to Machine Protection System for the new SwissFEL accelerator. A new combined EPICS/Linux driver has been developed at PSI, to allow for simple and mostly automatic setup of various EtherCAT configurations. The new driver is capable of automatic scanning of the existing device and module layout, followed by self-configuration and finally autonomous operation of the EtherCAT bus real-time loop. If additional configuration is needed, the driver offers both user- and kernel-space APIs, as well as the command line interface for fast configuration or reading/writing the module entries. The EtherCAT modules and their data objects (entries) are completely exposed by the driver, with each entry corresponding to a virtual file in the Linux procfs file system. This way, any user application can read or write the EtherCAT entries in a simple manner, even without using any of the supplied APIs. Finally, the driver offers EPICS interface with automatic template generation from the scanned EtherCAT configuration.

MOPGF029	Personnel Protection System Upgrade for the LCLS Electron Beam Linac	linac, operation, PLC, EPICS	157
	C. Cyterski, E.P. Chin SLAC, Menlo Park, California, USA
	As facilities age and evolve, constant effort is needed in upgrading control system infrastructure; this applies to all aspects of an accelerator facility. Portions of the Personnel Protection System of the Linac Coherent Light Source are still relying on a legacy, relay-based Safety System. An upgrade is underway to modernize these systems using Siemens S7-300 Safety PLCs and Pilz PNOZMulti programmable controllers. The upgrade will be rolled out over multiple years requiring the implementation to be fully compatible with adjacent legacy system while setting the foundation for the new generation system. The solution relies on a modularized safety system which can be deployed in a short time (1 month) while being flexible enough to adapt to the evolving needs over the next 20 years.

MOPGF030	Upgrade of the Control and Interlock Systems for the Magnet Power Supplies in T2K Primary Beamline	PLC, EPICS, operation, proton	160
	K. Nakayoshi, Y. Fujii, K. Sakashita KEK, Tsukuba, Japan
	T2K is a long-baseline neutrino oscillation experiment at J-PARC in Japan. High intensity neutrino/antineutrino beam is generated and propagates 295km to Super-Kamiokande. High intensity proton beam, 350 kW in May 2015, is extracted from Main Ring synchrotron, guided through a primary proton beamline to a graphite target using normal-conducting (NC) magnets and super-conducting combined-function magnets. In October 2014, we replaced all the power supplies (PSs) for NC magnets with newly developed PSs. We also developed new control system based on EPICS and PLCs, putting emphasis on the safe operation of power supplies, and integrated it into the existing interlock system. Consequently the latency time for the interlock system was improved. We report the actual implementation and operation results of these developments.

MOPGF032	Installation of a Hot-Swappable Spare Injector Laser System for the SLAC Linac Coherent Light Source	laser, electron, timing, interface	163
	S.C. Alverson, G.W. Brown, F.-J. Decker, S. Gilevich, S. Vetter SLAC, Menlo Park, California, USA
	LCLS is a facility for generation of very short duration, highly intense x-ray pulses which requires an extremely reliable photocathode electron source. In order to maintain high up-time (>95%) for the experimenters, operations rely on a maintenance program for active laser components as well as on built-in redundancy in case of failure. To accomplish this, a duplicate laser system was installed, allowing for quick swap between the active system and the spare in the event of a malfunction or for planned maintenance. As an added bonus, this redundant system provides additional possibilities for science as both laser systems can also be run to the cathode simultaneously to create multiple particle bunches. Diagnostics were put in place to maintain both special and temporal overlap and allow for the fast switching between systems by operations personnel while still remaining within the safety envelope. This was done for both the primary UV drive laser as well as the secondary IR "heater" laser. This paper describes the installation challenges and design architecture for this backup laser system.

MOPGF033	New Developments on EPICS Drivers, Clients and Tools at SESAME	EPICS, timing, Linux, Ethernet	167
	I. Saleh, Y.S. Dabain, A. Ismail SESAME, Allan, Jordan
	SESAME is a 2.5 GeV synchrotron light source under construction in Allan, Jordan. The control system of SESAME is based on EPICS and CSS. Various developments in EPICS drivers, clients, software tools and hardware have been done. This paper will present some of the main achievements: new linux-x86 EPICS drivers and soft IOCS developed for the Micro-Research Finland event timing system replacing the VME/VxWorks-based drivers; new EPICS drivers and clients developed for the Basler GigE cameras; an IOC deployment and management driver developed to monitor the numerous virtual machines running the soft IOCs, and to ease deployment of updates to these IOCs; an automated EPICS checking tool developed to aid in the review, validation and application of the in-house rules for all record databases; a new EPICS record type (mbbi2) developed to provide alarm features missing from the multibit binary records found in the base distribution of EPICS; and a test of feasibility for replacing serial terminal servers with low-cost computers.

Mizukawa Mitsubishi Electric System & Service Co., Ltd, Tsukuba, Japan H.S. Saotome, M. Takagi Kanto Information Service (KIS), Accelerator Group, Ibaraki, Japan
	Toward SuperKEKB project, the injector linac upgrade is ongoing for aiming at the stable electron/positron beam operation with low emittance and high intensity bunch charge. To obtain such high quality beam, we have being commissioning many newly developed subsystems including a low emittance photocathode rf gun since October of 2013. Eventually, we will perform the simultaneous top-up for the four independent storage rings including two light sources. The stable beam operation as long as possible is desired since the prospective physics results strongly depends on the reliability and availability of accelerator operation. Since the middle stage of KEKB project, the injector linac control system has been gradually transferred to the EPICS based one from the in-house system based on RPC. We are expanding the existing control system for the newly installed devices like a network attached power supply, timing jitter monitoring system, and so on. In addition, many commissioning tools are now under development to accelerate the high quality beam development. In this paper, we will describe the present status of injector linac control system and future plan in detail.

MOPGF036	Control System Developments at the Electron Storage Ring DELTA	software, network, EPICS, hardware	173
	D. Schirmer, A. Althaus, F.H. Bahnsen DELTA, Dortmund, Germany
	Increasing demands, mandatory replacement of obsolete controls equipment as well as the introduction of new soft- and hardware technologies with short innovation cycles are some of the reasons why control systems need to be revised continuously. Thus, also at the EPICS-based DELTA control system, several projects have been tackled in recent years: (1) Embedding the new CHG-based short-pulse facility for VUV and THz radiation required, for example, the integration of IP-cameras, Raspberry-Pi PCs and EtherCat/TwinCat wired I/O-devices. (2) The request for a staff-free control room led to the programming of new web applications using Python and the Django framework. This development resulted in a web-based interlock system that can be run, amongst others, on Android-based mobile devices. (3) The virtualization infrastructure for server consolidation has been extended and migrated from XEN to the kernel based KVM approach. (4) I/O-units which were connected via conventional fieldbus systems (CAN, GPIB, RS-232/485), are now gradually replaced by TCP/IP-controlled devices. This paper describes details of these upgrades and further new developments.

	S. L. Hoobler, S.C. Alverson, C. Cyterski, R.C. Sass SLAC, Menlo Park, California, USA
	For years, accelerator operators at the SLAC National Accelerator Laboratory (SLAC) have favored hardware knobs in the control room for accelerator tuning. Hardware knobs provide a tactile, intuitive, and efficient means of adjusting devices. The evolution of separate control systems for different accelerator facilities at SLAC has resulted in multiple flavors of knob hardware and software. To improve efficiency, space usage, and ease of use, the knob systems have been upgraded and integrated.

MOPGF039	TIP: An Umbrella Application for all SCADA-Based Applications for the CERN Technical Infrastructure	laser, operation, interface, framework	184
	F. Varela, Ph. Gayet, P. Golonka, M. Gonzalez-Berges, J. Pache, P. Sollander CERN, Geneva, Switzerland L. Goralczyk AGH University of Science and Technology, Kraków, Poland
	The WinCC Open Architecture (OA) SCADA package and the controls frameworks (UNICOS, JCOP) developed at CERN were successfully used to implement many critical control systems at CERN. In the recent years, the supervision and the controls of many technical infrastructure systems (electrical distribution, cooling and ventilation, etc.) were rewritten to use this standard environment. Operators at the Technical Infrastructure desk, who monitor these systems, are forced to continuously switch between the applications that allow them to monitor these infrastructure systems. The Technical Infrastructure Portal (TIP) was designed and is being developed to provide centralized access to all technical infrastructure systems and extend their functionality by linking to a powerful localization system based on GIS. Furthermore, it provides an environment for operators to develop views that aggregate data from different sources, like cooling and electricity.

MOPGF040	Keck Telescope Control System Upgrade	software, hardware, network, operation	188
	K.T. Tsubota, J.A. Mader W.M. Keck Observatory, Kamuela,, Hawaii, USA
	The Keck telescopes, located at one of the world's premier sites for astronomy, were the first of a new generation of very large ground-based optical/infrared telescopes with the first Keck telescope beginning science operations in May of 1993, and the second in October of 1996. The components of the telescopes and control systems are more than 15 years old. The upgrade to the control systems of the telescopes consists of mechanical, electrical, software and network components with the overall goals of improving performance, increasing reliability, addressing serious obsolescence issues and providing a knowledge refresh. This paper is a continuation of one published at the 2013 conference and will describe the current status of the control systems upgrade. It will detail the implementation and testing for the Keck II telescope, including successes and challenges met to date. Transitioning to nighttime operations will be discussed, as will implementation on the Keck I telescope.

	At LNL it is being carried out an upgrade campaign of the control systems of the accelerator complex. The two main goals are standardization of hardware and software and system interoperability. EPICS has been chosen as the standard framework for developing new control systems; this will address software standardization and system interoperability. In order to achieve hardware standardization, a new EPICS IOC is under development, which will become a basic construction block for all future control systems. The COM (Computer-on-Modules) from factor has been chosen as the hardware platform for the IOC, along with the peripheral devices needed for developing all the foreseen control system at LNL. Prototypes of this IOC has been developed using ADLINK's Type 6 COM Express modules on generic carrier boards with DIO, ADC and DAC expansion boards. These prototypes have been tested under typical applications at LNL in order to validate the hardware platform choice. Experimental results show that the performance of the IOC in terms of effective resolution (ENOB and bias error), sample rates and CPU usage is suitable for satisfying the requirements of the control systems.

MOPGF045	MEBT and D-Plate Control System Status of the Linear IFMIF Prototype Accelerator	EPICS, quadrupole, operation, diagnostics	197
	J. Calvo, D. Jiménez-Rey, E. Molina Marinas, J. Mollá, I. Podadera CIEMAT, Madrid, Spain
	Funding: This work has been partially funded by the Spanish Ministry of Economy and Competitiveness, under projects OPTIMHAC FIS2013-40860-R and IFMIF-EVEDA II. Ref: AIC-A-2011-0654. Linear IFMIF* Prototype Accelerator (LIPAc), Rokkasho, Japan, comprises a succession of devices and systems that accelerate a deuteron beam up to 9 MeV with a current of 125 mA, generating a power of 1.125 MW, and transport it up to a beam dump. The beam power becomes critical from the point of view of losses; even tiny losses must be avoided. This fact, and the complexity of the accelerator operation, requires a coherent strategy when designing, commissioning and optimizing the accelerator control system, specifically focused in the control systems of the Medium Energy Beam Transport (MEBT) and the Diagnostic Plate (DP, a movable set of diagnostics). Both systems are essential to validate the performance of the accelerator and particularly the ion source, Radio Frequency (RF) and Radio Frequency Quadrupole (RFQ) systems. This contribution will describe the recent advances in the control architectures and the EPICS based developments achieved in MEBT for the motion control of bunchers and scrapers, control of the power supplies in quadrupoles and steerers, and refrigeration and vacuum. Besides, control of fluorescence profile monitors (FPMs) in the D-Plate is displayed. *IFMIF, the International Fusion Materials Irradiation Facility, is an accelerator-based neutron source that will use Li (d, xn) reactions to generate a flux of neutrons with a broad peak at 14 MeV.

	Funding: Work supported by XT.Tran, M.Cerato, G.Renaud, E.Fonda and SAMBA Beamline staff, Delta Tau Ldt., IMO JEAMBRUN AUTOMATION, Observatory-Sciences Ldt. SOLEIL is a third generation synchrotron radiation source located near Paris in France. REVOLUTION (REconsider Various contrOLler for yoUr motion) is the motion controller upgrade project currently in progress at SOLEIL. It was initiated to maintain the facility operations by addressing the risk of hardware obsolescence in motion control but at the same time making room for complex applications requirements to face new high performance challenges. In order to achieve these considerations, SOLEIL's strategy move was to go from a single controller for all applications to two motion controllers. A first Controller GALIL DMC-4183 was chosen to succeed the previous version DMC-2182. Both controllers can be integrated in the existing architecture with little hardware and software adaptation enabling full compatibility with the existing architecture. A second controller, Delta Tau Power Brick, has been selected as a HIGH PERFORMANCE solution providing advanced functionality. The CLASSIC controller upgrade is about to be completed and the integration of Power Brick into the SOLEIL control system is ongoing. The system complexity is abstracted by embedding processing functions into low-level code and giving end-users a simple high-level interface. The work done to structure the interfacing and standardization of the controller are detailed in this paper.

	Instrument control at ISIS is in the process of migrating from a mainly locally developed system to an EPICS based system. The new control system, called IBEX, was initially used during commissioning of a new instrument prior to a long maintenance shutdown. This first usage has provided valuable feedback and significant progress has been made on enhancing the system during the facility maintenance period in preparation for the move onto production use. Areas that will be of particular interest to scientists in the future will be linking feedback from live data analysis with instrument control and also providing a simple and powerful scripting interface for facility users. In this paper we will cover the architecture and design of the new control system, our choices of technologies, how the system has evolved following initial use, and our plans for moving forward.

MOPGF049	100Hz Data Acquisition in the TANGO Control System at the Max IV Linac	TANGO, linac, hardware, electron	209
	P.J. Bell, V.H. Hardion, V. Michel MAX-lab, Lund, Sweden
	The MAX IV synchrotron radiation facility is currently being constructed in Lund, Sweden. A linear accelerator serves as the injector for the two storage rings and also as the source of short X ray pulses, in which mode it will operate with a 100Hz repetition rate. The controls system, based on TANGO, is required to collect and archive data from several different types of hardware at up to this 100Hz frequency. These data are used for example in offline beam diagnostics, for which they must be associated to a unique electron bunch number. To meet these requirements, the timing performance of the hardware components have been studied, and a TANGO Fast Archiver device created. The system is currently in the deployment phase and will play an important role in allowing the linac and Short Pulse Facility reach their 100Hz design goal

	Funding: The ELI-ALPS project (GOP-1.1.1-12/B-2012-000, GINOP-2.3.6-15-2015-00001) is supported by the European Union and co-financed by the European Regional Development Fund. ELI-ALPS will provide a wide range of attosecond pulses which will be used for performing experiments by international research groups. ELI-ALPS will use the TANGO Controls framework to build up the central control system and to integrate the autonomous subsystems regarding software monitoring and control. Beside a robust central and integrated control system a flexible and dynamic high level environment could be beneficial. The envisioned users will come from diverse fields including chemistry, biology, physics or medicine. Most of the users will not have programming or scripting background. Meanwhile workflow system provides visual programming facilities where the logics can be drawn, which is understandable by the potential users. We have integrated TANGO into the Kepler workflow system because it gives a lot of actors for all natural scientific fields. Moreover it has the potential for running the workflows on HPC or GRID resources. We demonstrated the usability of the development with a beamline simulation. The TANGO-Kepler integration provides an easy-to-use environment for the users therefore it can facilitate e.g. the standardization of measurements protocols as well.

MOPGF052	A Framework for Hardware Integration in the LHCb Experiment Control System	hardware, interface, experiment, detector	221
	L.G. Cardoso, F. Alessio, J. Barbosa, C. Gaspar, R. Schwemmer CERN, Geneva, Switzerland P-Y. Duval CPPM, Marseille, France
	LHCb is one of the four experiments at the LHC accelerator at CERN. For the LHCb upgrade, hundreds of new electronics boards for the central data acquisition and for the front-end readout of the different sub-detectors are being developed. These devices will need to be integrated in the Experiment Control System (ECS) that drives LHCb. Typically, they are controlled via a server running on a PC which allows the communication between the hardware registers and the experiment SCADA (WinCC OA). A set of tools was developed that provide an easy integration of the control and monitoring of the devices in the ECS. The fwHw is a tool that allows the abstraction of the device models into the ECS. Using XML files describing the structure and registers of the devices it creates the necessary model of the hardware as a data structure in the SCADA. It allows then the control and monitoring of the defined registers using their name, without the need to know the details of the hardware behind. The fwHw tool also provides the facility of defining and applying recipes - named sets of configuration parameters which can be used to easily configure the hardware according to specific needs.

MOPGF056	Synchronising High-Speed Triggered Image and Meta Data Acquisition for Beamlines	EPICS, hardware, data-acquisition, framework	225
	N. De Maio, A.P. Bark, T.M. Cobb, J.A. Thompson DLS, Oxfordshire, United Kingdom
	High-speed image acquisition is becoming more and more common on beamlines. As experiments increase in complexity, the need to record parameters related to the environment at the same time increases with them. As a result, conventional systems for combining experimental meta data and images often struggle to deliver at a speed and precision that would be desirable for the experiment. We describe an integrated solution that addresses those needs, overcoming the performance limitations of PV monitoring by combining hardware triggering of an ADC card, coordination of signals in a Zebra box* and three instances of area-Detector streaming to HDF5 data. This solution is expected to be appropriate for frame rates ranging from 30Hz to 1000Hz, with the limiting factor being the maximum speed of the camera. Conceptually, the individual data streams are arranged in pipelines controlled by a master Zebra box, expecting start/stop signals on one end and producing the data collections at the other. This design ensures efficiency on the acquisition side while allowing easy interaction with higher-level applications on the other. *T. Cobb, Y. Chernousko, I.

MOPGF058	Neutron Scattering Instrument Control System Modernization - Front-End Hardware and Software Adaption Problems	TANGO, device-server, detector, software	233
	M. Drochner, L. Fleischhauer-Fuss, H. Kleines, M. Wagener, S. van Waasen FZJ, Jülich, Germany
	When the FRM-2 neutron source went into operation (2002) and many instruments were moved from the closed-down Jülich reactor to the new facility, it was agreed on a choice of front-end hardware and the TACO middleware from ESRF. To keep up with software standards, it was decided recently to switch to TACO's successor - the TANGO control software. For a unified "user experience", new graphical user interface software "NICOS-2" is being developed by the software group at FRM2. While general semantics of TACO and TANGO don't look very different at a first glance, and adaption of device servers seemed to be straightforward at first, various problems in practical operation were found. The problems were due to differences in state handling, timing behavior and error reporting. These problems, and the changes that had to be made to ensure reliable operation again, will be described.

	Forschungszentrum Jülich has been operating the neutron Instrument DNS at the neutron source FRM II for about 10 years. DNS is a time of flight neutron spectrometer with polarization analysis that experienced a major upgrade in 2014 and 2015. During the upgrade DNS was equipped with new electronics and a new control and data acquisition system, including a transition from the existing TACO system to its successor TANGO. On the client side the NICOS software developed at FRM II is used for the implementation of measurement operations and user interface. The design of the new control and data acquisition system is presented and the lessons learned by the introduction of TANGO are reported.

MOPGF065	Motion Control on the Max IV Soft X-Ray Beamlines With Tango and Sardana	GUI, TANGO, synchrotron, software	240
	M. Lindberg, J. Forsberg, L. Kjellsson, A.M. Milan, C. Såthe, P. Sjöblom, S. Urpelainen MAX-lab, Lund, Sweden
	MAX IV Laboratory, a synchrotron facility in Lund, has selected TANGO as the control system framework for the entire facility. On the beamlines that are being built the Python-based SCADA (supervisory control and data acquisition) system Sardana will be used for experimental control. SPECIES, one out of eight new soft X-ray beamlines, is used as a test bench for evaluating the chosen standards. Sardana is used to control the energy setting of the PGM (plane grating monochromator) as well as to provide macros and other utilities for the user. Generic Taurus GUIs and a SVG-synoptic give the user a way to interact with the control system and display relevant information. The standardized graphical interfaces give a familiar look and feel across the entire facility. All motorized axes are controlled with the IcePAP motion controller. For the axes of the PGM, the IcePAP driver operates in hardware closed loop. Special care is taken in order to avoid slow and inaccurate movements of the PGM energy due to the non-linear relationship between the motors and the angular encoders.

MOPGF066	Synchronized Ramping of Magnet Power Supplies for Streamlined Operation at Energy Recovery Linac (ERL) and Electron Lens (e-Lens)	software, solenoid, electron, operation	244
	P. K. Kankiya, J.P. Jamilkowski, T. Samms BNL, Upton, Long Island, New York, USA
	Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-SC0012704 with the U.S. Department of Energy. Synchronous ramping of an assembly of magnets is critical for operation of beam in an accelerator. Magnet currents must remain within the operational limits to avoid dis-alignment of electron beam. In order to comply with the design specifications of ERL and ELENS project , two different software control mechanisms have been developed. The ramp profile is automated and maintained by tracking current in all dipole magnets at ERL and superconducting solenoid magnets at ELENS. This mechanism speeds up operations and adds a level of protection. The purpose of this application is to reduce unnecessary interlocks of the personnel protection system. This paper will describe the power supply arrangement, communication mechanism and the state machine algorithm used for feedback and control. A report on operating experience will be presented.

MOPGF067	MeerKAT Control and Monitoring System Architecture	interface, monitoring, network, FPGA	247
	N. Marais SKA South Africa, National Research Foundation of South Africa, Cape Town, South Africa
	Funding: SKA South Africa, National Research Foundation of South Africa, Department of Science and Technology. The 64-dish MeerKAT radio telescope, currently under construction, comprises several loosely coupled independent subsystems, requiring a higher level Control and Monitoring (CAM) system to operate as a coherent instrument. Many control-system architectures are bus-like, clients directly \mbox{receiving} monitoring points from Input/Output Controllers; instead a multi-layer architecture based on point-to-point Karoo Array Telescope Control Protocol (KATCP) connections is used for MeerKAT. Clients (e.g. operators or scientists) only communicate directly with the outer layer of the telescope; only telescope interactions required for the given role are exposed to the user. The layers, interconnections, and how this architecture is used to meet telescope system requirements are described. Requirements include: Independently controllable telescope subsets; dynamically allocating telescope resources to individual users or observations, preventing the control of resources not allocated to them; commensal observations sharing resources; automatic detection of, and responses to, system-level alarm events; high level operator controls and health displays; automatic execution of scheduled observations.

Kim, S.Y. Rah PAL, Pohang, Republic of Korea
	The increased brilliance of state-of-the-art Synchrotron radiation sources and Free Electron Lasers require imaging detectors capable of taking advantage of these light source facilities. The PERCIVAL ("Pixelated Energy Resolving CMOS Imager, Versatile and Large") detector is being developed in collaboration between DESY, Elettra Sincrotrone Trieste, Diamond Light Source and Pohang Accelerator Laboratory. It is a CMOS detector targeting soft X-rays < 1 KeV, with a high resolution of up to 13 M pixels reading out at 120 Hz, producing a challenging data rate of 6 GB/s. The controls and data acquisition system will include a SDK to allow integration with third party control systems like Tango and DOOCS; an EPICS areaDetector driver will be included by default. It will make use of parallel readout to keep pace with the data rate, distributing the data over multiple nodes to create a single virtual dataset using the HDF5 file format for its speed advantages in high volumes of regular data. This paper presents the design of the control system software for the Percival detector, an update of the current state of the implementation carried out by Diamond Light Source.

MOPGF071	Sodium Laser Guide Star Emulation	laser, hardware, optics, software	255
	I.A. Price Research School of Astronomy & Astrophysics, Australian National University, Weston Creek, Australia R. Conan GMTO Corporation, Pasadena, USA
	In the era of extremely large telescopes (ELT) an adaptive optics (AO) system with artificial guide stars is an essential part of the optics between the source and the instrument. For the Giant Magellan Telescope these guide stars are formed by stimulating emission from Sodium atoms in the atmosphere with lasers launched from the side of the telescope. Moreover, they are resolved by the adaptive optics system so Shack-Hartmann wavefront sensors record elongated spots. Cost effective proof-of-concept systems for investigating control algorithms must be built for deployment in the lab or on small telescopes. We present a hardware and software system that mimics the propagation of a single laser guide star (LGS) through the Earth's atmosphere and the optics of the Giant Magellan Telescope, using source motion and brightness modulation to simulate the source extension. A service oriented architecture allows adaptive optics scientists to construct images from different LGS asterisms and build non-real-time closed-loop control systems in high-level languages.

MOPGF077	Drift Control Engines Stabilize Top-Up Operation at BESSY II	feedback, injection, operation, experiment	262
	T. Birke, F. Falkenstern, R. Müller, A. Schälicke HZB, Berlin, Germany
	Funding: Work supported by BMBF and Land Berlin. Full stability potential of orbit and bunch-by-bunch-feedback controlled top-up operation becomes available to the experimental users only if the remaining slow drifts of essential operational parameters are properly compensated. At the light source BESSY II these are the transversal tunes as well as the path length and energy. These compensations are realized using feedback control loops together with supervising state machines. Key to the tune control is a multi-source tune determination algorithm. For the path length correction empirical findings are utilized. All involved software systems and data-paths are sketched.

MOPGF079	European XFEL Cavities Piezoelectric Tuners Control Range Optimization	cavity, operation, LLRF, linac	266
	W. Cichalewski, A. Napieralski TUL-DMCS, Łódź, Poland J. Branlard, Ch. Schmidt DESY, Hamburg, Germany
	The piezo based control of the superconducting cavity tuning has been under the development over last years. Automated compensation of Lorentz force detuning of FLASH and European X-FEL resonators allowed to maintain cavities in resonance operation even for high acceleration gradients (in range of 30 MV/m). It should be emphasized that cavity resonance control consists of two independent subsystems. First of all the slow motor tuner based system can be used for slow, wide range mechanical tuning (range of hundreds of kHz). Additionally the piezo tuning system allows for fine, dynamic compensation in a range of ~1 kHz. In mentioned pulse mode experiments (like FLASH), the piezo regulation budget should be preserved for in-pulse detuning control. In order to maintain optimal cavity frequency adjustment capabilities slow motor tuners should automatically act on the static detuning component at the same time. This paper presents work concerning development, implementation and evaluation of automatic superconducting cavity frequency control towards piezo range optimization. FLASH and X-FEL dedicated cavities tuning control experiences are also summarized.

	G.A. Fatkin, A.M. Batrakov, I.V. Ilyin, M.Yu. Vasilyev BINP SB RAS, Novosibirsk, Russia G.A. Fatkin NSU, Novosibirsk, Russia
	NICA (Nuclotron based Ion Collider fAcility) is an accelerator complex, which is being built in JINR (Dubna, Russia). The system described in this paper is controlling the RF stations of booster, the first element of the NICA complex. The two devices are parts of the Control System: Intellectual Controller and Tester module. The first one is designed for precise measurement of magnetic field, generation of the acceleration frequency in accordance with measured field and control RF power and pre-amplifiers. Intellectual Controller is a real-time feed-forward system with 20 ums loop time. It is based on ARM microcontroller and bare-metal control programs are used to reach maximum performance. Approaches that were used to achieve maximum performance are elaborated and presented in this paper. The second part of system - Tester is a simulator for tuning and checking the RF stations before start of operations or in absence of real accelerator. The achieved accuracy in chain 'magnetic field' - 'acceleration frequency' is better than 5*10^-5. Plans on feedback incorporation to stabilize ion beam behavior via frequency and phase tuning are discussed.

MOPGF088	Integrating the Measuring System of Vibration and Beam Position Monitor to Study the Beam Stability	monitoring, data-acquisition, vacuum, network	277
	C. H. Huang, Y.-S. Cheng, P.C. Chiu, K.T. Hsu, K.H. Hu, C.Y. Liao NSRRC, Hsinchu, Taiwan
	For a low emittance light source, beam orbit motion needs to be controlled within submicron for obtaining a high quality light. Magnets vibration especially quadruples will be one of the main sources to destroy the beam stability. In order to study the relationship between vibration and beam motion, it is highly desirable to use a synchronous data acquisition system which integrates measurement of vibration and beam position monitor systems especially for the coherence analysis. For a larger vibration such as earthquakes are also deleterious to beam stability or even make the beam trip due to the quench of superconducting RF cavity. A data acquisition system integrated with an earthquake detector is also quite necessary to show and archive the data on the control system. The data acquisition systems of vibration and earthquake measurement system are summarized in this report. The relationship between the beam motion and magnets vibration will also study here.

MOPGF090	Control of Fast-Pulsed Power Converters at CERN Using a Function Generator/Controller	timing, network, software, Ethernet	281
	R. Murillo-Garcia, Q. King, M. Magrans de Abril CERN, Geneva, Switzerland
	The electrical power converter group at CERN is responsible for the design of fast-pulsed power converters. These generate a flat-top pulse of the order of a few milliseconds. Control of these power converters is orchestrated by an embedded computer, known as the Function Generator/Controller (FGC). The FGC is the main component in the so-called RegFGC3 chassis, which also houses a variety of purpose-built cards. Ensuring the generation of the pulse at a precise moment, typically when the beam passes, is paramount to the correct behaviour of the accelerator. To that end, the timing distribution and posterior handling by the FGC must be well defined. Also important is the ability to provide operational feedback, and to configure the FGC, the converter, and the pulse characteristics. This paper presents an overview of the system architecture as well as the results obtained during the commissioning of this control solution in CERN's new Linac4.

MOPGF091	White-Rabbit Based Revolution Frequency Program for the Longitudinal Beam Control of the CERN PS	ion, proton, FPGA, injection	286
	D. Perrelet, Y. Brischetto, H. Damerau, A.V. Villanueva CERN, Geneva, Switzerland D. Oberson HEIA-FR, Fribourg, Switzerland M.V. Sundal IST, Lisboa, Portugal
	The measured bending field of the CERN Proton Synchrotron (PS) is received in real-time by the longitudinal beam control system and converted into the revolution frequency used as set-point for beam phase and radial loops. With the renovation of the bending field measurement system the transmission technique is changed from a differential sequence of pulses, the so-called B-train, to a stream of Ethernet frames based on the White Rabbit protocol. The packets contain field, its derivative and auxiliary information. A new frequency program for the conversion of the bending field into the revolution frequency, depending also on parameters like radius of the accelerator and the particle type, has been developed. Instead of storing large conversion tables from field to frequency for fixed parameters, the frequencies are directly calculated in programmable logic (FPGA). In order to reduce development time and keep flexibility, the conversion is processed in real-time in the FPGA using Xilinx floating-point primitives mapped by a higher level tool Simulink System Generator. Commissioning with beam of the new frequency program in the PS is progressing. Authors: D. Perrelet, Y. Brischetto, H. Damerau, D. Oberson, M. Sundal, A. Villanueva

	C.E. Peters, C. Dickerson, F. Garcia, M.A. Power ANL, Argonne, Illinois, USA
	Funding: This work is supported by the U.S. DOE, Office of Nuclear Physics, contract No. DE-AC02-06CH11357. This research used resources of ANLs ATLAS facility, which is a DOE Office of Science User Facility The Accelerator R&D Group within the Argonne National Laboratory (ANL) Physics Division maintains a beam dynamics model named TRACK. This simulation code has the potential to assist operators in visualizing key performance parameters of the Argonne Tandem Linear Accelerating System (ATLAS). By having real-time access to visual and animated models of the particle beam transverse and longitudinal phase spaces, operators can more quickly iterate to a final machine tune. However, this effort requires a seamless integration into the control system, both to extract initial run-time information from the accelerator, and to present the simulation results back to the users. This paper presents efforts to pre-process, batch execute, and visualize TRACK particle beam physics simulations in real-time via the ATLAS Control System.

MOPGF097	Architecture of Transverse Multi-Bunch Feedback Processor at Diamond	feedback, FPGA, EPICS, experiment	298
	M.G. Abbott, G. Rehm, I.S. Uzun DLS, Oxfordshire, United Kingdom
	We describe the detailed internal architecture of the Transverse Multi-Bunch Feedback processor used at Diamond for control of multi-bunch instabilities and measurement of betatron tunes. Bunch by bunch selectable control over feedback filters, gain and excitation allows fine control over feedback, allowing for example the single bunch in a hybrid or camshaft fill pattern to be controlled independently from the bunch train. It is also possible to excite all bunches at a single frequency while simultaneously sweeping the excitation for tune measurement of a few selected bunches. The single frequency excitation has been used for continuous measurement of the beta-function. A simple programmable event sequencer provides support for up to 7 steps of programmable sweeps and changes to feedback and excitation, allowing a variety of complex and precisely timed beam characterisation experiments including grow-damp measurements in unstable conditions and programmed bunch cleaning. Finally input and output compensation filters allow for correction of front end and amplifier phasing at higher frequencies.

	I.S. Uzun, T.M. Cobb, A.M. Cousins, M.T. Heron DLS, Oxfordshire, United Kingdom Y.-M. Abiven, J. Bisou, P. Monteiro, G. Renaud SOLEIL, Gif-sur-Yvette, France
	Synchrotron SOLEIL and Diamond Light Source are two third generation light sources located respectively in France and the UK. In the past 5 years, both facilities separately developed their own platform permitting encoder processing to synchronize motion systems and acquisition during experiments, SPIETBOX by SOLEIL and Zebra by Diamond. New operational requirements for simultaneous and multi-technique scanning, and support of multiple encoder standards have been identified by both institutes. In order to address these a collaborative project has been initiated between SOLEIL and Diamond to realize a new 'Position and Acquisition' processing platform, called PandA. The PandA project addresses current systems' limitations in term of obsolescence and need for more processing power. Its design is going to be a 1U standalone system powered by a Xilinx Zynq SoC to implement a configurable set of logic functionalities. It will provide a flexible and open solution to interface different third party hardware (detectors and motion Controllers). This paper details the organization of this collaboration, sharing technical leadership between both institutes and the status of the project.

	G. Valentino, G. Baud, M. Gąsior, S. Jackson, L.K. Jensen, J. Olexa, S. Redaelli, J. Wenninger CERN, Geneva, Switzerland
	In the Large Hadron Collider (LHC), over 100 movable collimators are connected to a three-tier control system which moves them to the required settings throughout the operational cycle from injection to collision energy. A dedicated control system was developed to align the collimators to the beam during machine commissioning periods and hence determine operational settings for the active run. During Long Shutdown 1, the control system was upgraded to allow beam-based alignments to be performed using embedded beam position monitors in 18 newly installed collimators as well as beam loss monitors. This paper presents the new collimation controls architecture for LHC Run II along with several modifications in the Java-based application layer.

	S. Blanchard, F. Antoniotti, R. Ferreira, P. Gomes, A. Gutierrez, B. Jenninger, F. Mateo, H.F. Pereira CERN, Geneva, Switzerland L. Kopylov, S. Merker IHEP, Moscow Region, Russia
	NA62 is a fixed target experiment to measure very rare decays of Kaons at CERN Super Proton Synchrotron accelerator. The NA62 experiment line comprises several large detectors installed inside a vacuum vessel with a length of 250 m and an internal diameter of up to 2.8 m. The vacuum installation consists of 170 remote controlled pumps, valves and gauges. The operational specifications of NA62 require a complex vacuum control system: tight interaction between vacuum controllers and detector controllers, including pumping or venting vetoes, and detector start-stop interlocks; most of the valves are interlocked, including the large vacuum sector gate valves; the vacuum devices are driven by 20 logic processes. The vacuum control system is based on commercial Programmable Logical Controllers (Siemens PLC: S7-300 series) and a Supervisory Control And Data Acquisition application (Siemens SCADA: WINCC OA). The control software is built upon the standard framework used in CERN accelerators vacuum, with some specific developments. We describe the controls architecture, and report on the particular requirements and the solutions implemented.

	F. Mateo, F. Antoniotti, S. Blanchard, R. Ferreira, P. Gomes, A. Gutierrez, B. Jenninger, H.F. Pereira CERN, Geneva, Switzerland
	NA62 is the follow-up of the NA48 experiment, in the SPS North Area of CERN, and reuses a large fraction of its detectors and beam line equipment. Still, there are many new vacuum devices in the beam line (including pumps, valves & gauges), which required a thorough modification of the control system and a large number of new controllers, many of which were custom-made. The NA62 vacuum control system is based on the use of PLCs (Programmable Logic Controllers) and SCADA (Supervisory Control and Data Acquisition). The controllers and signal conditioning electronics are accessed from the PLC via a field bus (Profibus); optical fibre is used between surface racks and the underground gallery. The control hardware was completely commissioned during 2014. The nominal pressure levels were attained in all sectors of the experiment. The remote control of all devices and the interlocks were successfully tested. This paper summarizes the architecture of the vacuum control system of NA62, the types of instruments to control, the communication networks, the hardware alarms and the supervisory interface.

Prieto, B. Rio, H. Vestergard CERN, Geneva, Switzerland L. Kopylov, S. Merker, M.S. Mikheev IHEP, Moscow Region, Russia
	For two years (Spring 2013 - Spring 2015), the LHC went through its first long shutdown (LS1). It was mainly motivated by the consolidation of magnet interconnects, to allow operation with 6.5 TeV proton beams. Moreover, around the accelerator complex, many other systems were repaired, consolidated or upgraded, and several new installations came to life. The standardization of vacuum controls has progressed in the injectors, with the renovation of most of their obsolete equipment. In the LHC, many new instruments were added, the signal transmission integrity was improved, and the exposure to radiation was reduced in critical places. Several developments were needed for new equipment types or new operational requirements.

We have developed a control system configuration tool, which provides an easy-to-use interface for quick configuration of the entire facility. It uses Microsoft Excel as the front-end application and allows the user to quickly generate and deploy IOC configuration (EPICS start-up scripts, alarms and archive configuration) onto IOCs; start, stop and restart IOCs, alarm servers and archive engines, and more. The DCDB tool utilizes a relational database, which stores information about all the elements of the accelerator. The communication between the client, database and IOCs is realized by a REST server written in Python. The key feature of the DCDB tool is that the user does not need to recompile the source code. It is achieved by using a dynamic library loader, which automatically loads and links device support libraries. The DCDB tool is compliant with CODAC (used at ITER and ELI-NP), but can also be used in any other EPICS environment (e.g. it has been customized to work at ESS).

MOPGF110	Design Strategies in the Development of the Italian Single-dish Control System	software, operation, interface, Ethernet	330

	The Italian National Institute for Astrophysics (INAF) manages three radio telescopes: the Medicina and Noto dishes and the newly-built SRT. In order to make their capabilities more valuable to the scientific community, we started the DISCOS (Development of the Italian Single-dish COntrol System) project. DISCOS is implemented according to a distributed Component-Container model and hides to the users the differences among the telescopes by presenting the same user interface and the same data format. The complexity of coping with three heterogeneous instruments was handled designing a software development infrastructure with a wide monolithic codebase (libraries, components and generic interfaces), which is completely shared among the three product lines. This design permits to produce new software components with a minimum effort and to set up the same test suites for all the environments, thus leading to an affordable development and maintenance process. In this paper we illustrate the design strategies and the development techniques used to realize and optimize this common control software. We also provide a description of the project status and future plans.

MOPGF112	Measurements, Alarms and Interlocks in the Vacuum Control System of the LHC	vacuum, electronics, radiation, interlocks	338
	G. Pigny, F. Antoniotti, J-P. Boivin, N. Chatzigeorgiou, J. Gama, P. Gomes, P. Krakówski, H.F. Pereira CERN, Geneva, Switzerland
	In the LHC beam pipes and cryostats, the pressure measurement covers a wide range, from 1500 mbar down to 10^-11 mbar and even lower. If vacuum deteriorates, alarm signals are generated and sent to other systems, e.g. cryogenics, accelerating cavities, kicker magnets, and beam interlock. In addition, an unacceptable pressure rise in beam pipes generates interlocks to close the adjacent sector valves, thus isolating the sector, so that the pressure rise does not propagate. This paper describes the measurement chains, the alarms and interlocks logic used in the vacuum control system of the LHC. We analyze the possible signal degradation caused by ionizing radiation or due to cable length, shielding and grounding. The weaknesses of the existing vacuum measurement system are pointed out, and a prospective for improvement of the conditioning electronics is proposed. During the first LHC long shut down, several corrections were applied; the results of the tests after commissioning are also presented.

MOPGF113	Controls and Interlocks for the New Elettra Super Conducting Wiggler	vacuum, TANGO, wiggler, storage-ring	342
	L. Pivetta, F. Giacuzzo, G. Scalamera, D. Vittor Elettra-Sincrotrone Trieste S.C.p.A., Basovizza, Italy
	During the last two years, triggered by the construction of the XRD2 beamline, and to comply with the top-up operations, a complete refurbishment of the Elettra Super Conducting Wiggler (SCW) has been carried out. Alongside with the mechanical, cryogenic and electrical components, also the electronics, the control and interlock systems have been upgraded. The MVME5110 PowerPC single board computer, which is a standard in the Elettra control system, has been adopted, as well as RS232 communication modules, analog to digital converters and digital I/O lines. In order to cope with the high output power of the SCW, up to18 KW, the interlock system, protecting both the wiggler and the beamline front-end, has been completely redesigned. The control system software has been re-written from scratch using the TANGO software framework. The complete system has been tested during the second half of 2014 and is now fully operational.

MOPGF114	Controls Interface into the Low-Level RF System in the ARIEL e-Linac at TRIUMF	LLRF, ISAC, interface, linac	346
	J.J. Pon, K. Ezawa, R. Keitel, R.B. Nussbaumer, J.E. Richards, M. Rowe, P.J. Yogendran TRIUMF, Canada's National Laboratory for Particle and Nuclear Physics, Vancouver, Canada
	Phase 1 of TRIUMF Advanced Rare Isotope Laboratory (ARIEL) was completed in September 2014. At phase 1, the Low-Level RF (LLRF) system of ARIEL's electron linear accelerator (e-Linac) consists of a buncher and a deflector, one single-cavity injector cryomodule and the first cavity of two dual-cavity accelerating cryomodules. The model for the e-Linac LLRF system is largely based on the experience gained from the fully-commissioned TRIUMF ISAC-II linear accelerator (linac). Similarly, the EPICS-based Controls for the e-Linac LLRF builds on the lessons learned with the linac LLRF Controls. This paper describes the interface between the ARIEL Control System (ACS) and the e-Linac LLRF using EPICS ASYN/StreamDevice and a SCPI-like protocol. Also discussed are the ACS EDM displays and future plans for LLRF Controls.

MOPGF115	LabVIEW as a New Supervision Solution for Industrial Control Systems	LabView, PLC, database, framework	349
	O.Ø. Andreassen, F. Augrandjean, E. Blanco Vinuela, M.F. Gomez De La Cruz, A. Rijllart CERN, Geneva, Switzerland D. Abalo Miron University of Oviedo, Oviedo, Spain
	To shorten the development time of supervision applications, CERN has developed the UNICOS framework, which simplifies the configuration of the front-end devices and the supervision (SCADA) layer. At CERN the SCADA system of choice is WinCC OA, but for specific projects (small size, not connected to accelerator operation or not located at CERN) a more customisable SCADA using LabVIEW is an attractive alternative. Therefore a similar system, called UNICOS in LabVIEW (UiL), has been implemented. It provides a set of highly customisable re-usable components, devices and utilities. Because LabVIEW uses different programming methods than WinCC OA, the tools for automatic instantiation of devices on both the front-end and supervision layer had to be re-developed, but the configuration files of the devices and the SCADA can be reused. This paper reports how the implementation was done, it describes the first project implemented in UiL and an outlook to other possible applications.

MOPGF117	The Control System for Trim-Coil Relay-Selectors in J-PARC MR	EPICS, power-supply, PLC, operation	353
	K.C. Sato, N. Kamikubota, N. Yamamoto J-PARC, KEK & JAEA, Ibaraki-ken, Japan S. Igarashi KEK, Ibaraki, Japan S.Y. Yoshida Kanto Information Service (KIS), Accelerator Group, Ibaraki, Japan
	In J-PARC main ring, each of the main magnets (Dipole, Quadrupole, and Sextupole) has a trim-coil. The basic aim of trim-coil is to correct small deviation of each magnetic field. In addition, we have used them for other purposes, for example: (1) in Beam-Based-Alingnment studies, (2) as flux monitors, and (3) to make a short-circuit to reduce ripples of magnetic field. At a moment, trim-coils can be used for only one purpose. Relay-switches were introduced to change trim-coil connection to a device, which corresponds to the selected purpose. When the purpose is switched, 1,200 on-site relays have to be changed manually, distributed in three buildings. Thus, a control system for trim-coil relay-selectors was developed in winter, 2014-2015. EPICS tools and environment are used to develop the system. The system comprises PLC I/O modules with controller running EPICS on Linux. The system will be in operation after March, 2015. By using the system, a much easier switching of relay-switches than before, is expected.

MOPGF119	Design and Development of the ECR Ion Source Control System	vacuum, ion, PLC, ion-source	356
	H.J. Son, H. Jang, S. Lee, C.W. Son IBS, Daejeon, Republic of Korea
	Funding: This work is supported by the Rare Isotope Science Project funded by Ministry of Science, ICT and Future Planning(MSIP) and National Research Foundation(NRF) of Korea(Project No. 2011-0032011). The Rare Isotope Science Project at the Institute for Basic Science constructs the rare isotope accelerator (RAON) facility in South Korea. The stable ion beam as an ion source for the RAON accelerator could be generated by ECR ion source system. Therefore, it is mandatory to build ECR ion source control system that could be integrated into an accelerator control system easily. The vacuum control system is an essential part of the ECR control system, because of one vacuum chamber among three different voltage stages (ground, 50 kV, and 80 kV). The preliminary design and implementation of vacuum control system for the ECR ion source will be discussed. It is planned to use a PLC in order to communicate with a vacuum gauge and turbo pump controllers among multi-voltage stages (ground, 50 kV and 80 kV) by optical fibers connection. The PLC system has two major components: a digital I/O module that provides power to each component and standard RS-232 modules which are connected with the gauge & pump controllers. In addition, its extension plan to integrate the vacuum control system into the RAON accelerator control system based on system the EPICS framework, will be discussed.

MOPGF120	CAN Over Ethernet Gateways: A Convenient and Flexible Solution to Access Low Level Control Devices	interface, hardware, Ethernet, software	359
	G. Thomas, D. Davids CERN, Geneva, Switzerland O. Holme ETH, Zurich, Switzerland
	CAN bus is a recommended fieldbus at CERN. It is widely used in the control systems of the experiments to control and monitor large amounts of equipment (IO devices, front-end electronics, power supplies). CAN nodes are distributed over busses that are interfaced to the computers via PCI or USB CAN interfaces. These interfaces limit the possible evolution of the Detector Control Systems (DCS). For instance, PCI cards are not compatible with all computer hardware and new requirements for virtualization and redundancy require dynamic reallocation of CAN bus interfaces to different computers. Additionally, these interfaces cannot be installed at a different location than the front-end computers. Ethernet based CAN interfaces resolve these issues, providing network access to the field busses. The Ethernet-CAN gateways from Analytica (GmbH) were evaluated to determine if they meet the hardware and software specifications of CERN. This paper presents the evaluation methodology and results as well as highlighting the benefits of using such gateways in experiment production environments. Preliminary experience with the Analytica interfaces in the DCS of the CMS experiment is presented.

MOPGF121	Stripping Foil Displacement Unit Control for H⁻ Injection in PSB at CERN	vacuum, radiation, linac, injection	363
	P. Van Trappen, R. Noulibos, W.J.M. Weterings CERN, Geneva, Switzerland
	For CERN's Linac4 (L4) Proton Synchrotron Booster (PSB) injection scheme, slices of the 160 MeV H⁻ beam will be distributed to the 4 superposed synchrotron rings of the PSB. The beam will then be injected horizontally into the PSB by means of an H⁻ charge-exchange injection system using a graphite stripping foil to strip the electrons from the H⁻ ions. The foil and its positioning mechanism will be housed under vacuum inside a stripping foil unit, containing a set of six foils that can be mechanically rotated into the beam aperture. The band with mounted foils is controlled by a stepping motor while a resolver, micro-switches and a membrane potentiometer provide foil position feedback. The vicinity of the ionizing beam and vacuum requirements have constrained the selection of the above mentioned control system parts. The positioning and interlocking logic is implemented in an industrial Programmable Logic Controller (PLC). This paper describes the design of the stripping foil unit electronics and controls and presents the first results obtained from a test bench unit which will be installed in the Linac4 transfer line by the end of the 2015 for foil tests with beam.

MOPGF129	Understanding the Failure Characteristics of the Beam Permit System of RHIC at BNL	collider, simulation, ion, vacuum	382
	P. Chitnis, T.G. Robertazzi Stony Brook University, Stony Brook, New York, USA K.A. Brown BNL, Upton, Long Island, New York, USA
	Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-SC0012704 with the U.S. Department of Energy. The RHIC Beam Permit System (BPS) monitors the anomalies occurring in the collider and restores the machine to a safe state upon fault detection. The reliability of the BPS thus directly impacts RHIC availability. An analytical multistate reliability model of the BPS has been developed to understand the failure development and propagation over store length variation. BPS has a modular structure. The individual modules have joint survival distributions defined by competing risks with exponential lifetimes. Modules differ in functionality and input response. The overall complex behavior of the system is analyzed by first principles for different failure/success states of the system. The model structure changes according to the type of scenario. The analytical model yields the marginal survival distribution for each scenario versus different store lengths. Analysis of structural importance and interdependencies of modules is also examined. A former Monte Carlo model* is used for the verification of the analytical model for a certain store length. This work is next step towards building knowledge base for eRHIC design by understanding finer failure characteristics of the BPS. *P.

MOPGF131	Interlock System for Machine Protection at ThomX Accelerator	vacuum, PLC, dipole, operation	386
	N. ElKamchi, P. Gauron, H. Monard LAL, Orsay, France
	ThomX is a Compton based photons source. It aims to produce a compact and directional X-rays source, with high performance, high brightness and adjustable energy. The principal application fields are medical sciences, social technology and industry. An interlock system has been implemented for machine protection, especially to protect sensitive and essential equipment (magnets, vacuum system, etc.) during machine operation. ThomX interlock system is based on Programmable Logic Controller (PLC-Siemens S7-1500), it collects default signals from the different equipment of the machine, up to the central PLC which kills the beam, by stopping the RF or the injection, in case of problem (bad vacuum, magnets overheating, etc.). The interlock system consists of two levels. The first one is a local process, whose role is to monitor the variations of different parameters of the machine equipment, and generates a default signal in case of operation problem. The second level is the central PLC, which gathers and process all the default signals from subsystems, and stops the RF power in a very short time. Actually, the interlock system is under test, it will allow accelerator to work safely. C. Bruni et al.,'ThomX - Conceptual Design Report', 2009, pp.1-136.

MOPGF132	Building an Interlock: Comparison of Technologies for Constructing Safety Interlocks	PLC, FPGA, interlocks, ion	389
	T. Hakulinen, F. Havart, P. Ninin, F. Valentini CERN, Geneva, Switzerland
	Interlocks are an important feature of both personnel and machine protection systems for mitigating risks inherent in operation of dangerous equipment. The purpose of an interlock is to secure specific equipment or entire systems under well defined conditions in order to prevent accidents from happening. Depending on specific requirements for the level of reliability, availability, speed, and cost of the interlock, various technologies are available. Different approaches are discussed, in particular in the context of personnel safety systems, which have been built or tested at CERN during the last few years. Technologies discussed include examples of programmable devices, PLCs and FPGAs, as well as wired logic based on relays and special logic cards.

MOPGF134	Design of Fast Machine Protection System for the C-ADS Injection I	FPGA, interface, timing, network	393
	F. Liu, J. Hu, X.S. Jiang, Q. Ye IHEP, People's Republic of China G.H. Gong Tsinghua University, Beijing, People's Republic of China
	In this paper a new fast machine protection system is proposed. This system is designed for the injection Ι of C-ADS which fault reaction time requires less than 20us, and the one minute down time requires less than 7 times in a whole year. The system consist of one highly reliable control network based on a control board and some front IO sub-boards, and one nanosecond precision timing system using white rabbit protocol. The control board and front IO sub-board are redundant separately. The structure of the communication network is a combination structure of star and tree types which using the 2.5GHz optical fiber links the all nodes. This paper pioneered the use of nanosecond timing system based on the white rabbit protocol to determine the time and sequence of each system failure. Another advantage of the design is that it uses standard FMC and an easy extension structure which made the design is easy to use in a large accelerator.

The European XFEL is a 3.4km long X-ray Free Electron Laser in the final construction and commissioning phase in Hamburg. It will produce 27000 bunches per second at 17.5GeV. Early 2015 a first electron beam was produced in the RF-photo-injector and the commissioning of consecutive sections is following during this and next year. The huge number and variety of devices for the accelerator, beam line, experiment, cryogenic and facility systems pose a challenging control task. Multiple systems, including industrial solutions, must be interfaced to each other. The high number of bunches requires a tight time synchronization (down to picoseconds) and high performance data acquisition systems. Fast feedbacks from front-ends, the DAQs and online analysis system with a seamless integration of controls are essential for the accelerator and the initially 6 experimental end stations. It turns out that the European XFEL will be the first installation exceeding 2500 FPGA components in the MicroTCA form factor and will run one of the largest PROFIBUS networks. Many subsystem prototypes are already successfully in operation. An overview and status of the XFEL control system will be given.

SuperKEKB is the upgrade of KEKB, the asymmetric energy electron-positron collider for the B-factory experiment in Japan. It aims at the 40-times higher luminosity than the world record by KEKB. The KEKB control system has been built based on EPICS at the equipment layer and scripting languages at the operation layer. The SuperKEKB control system continues to employ these frameworks while we implement new features for the successful operation at such a high luminosity. As the commissioning of the SuperKEKB main storage rings is scheduled to start in 2016, the construction of the control system is now in the final phase. We have upgraded and reinforced the network system, server computers and operator consoles. Most of the VME-based IOCs (I/O Controllers), which has been widely used in KEKB, are upgraded while the PLC-based IOCs are also widely introduced. The new timing system has been developed in order to handle the complicated injection scheme of the SuperKEKB accelerator complex efficiently. The new beam abort trigger system and the new beam gate control system have been developed, and so on. The construction status of the SuperKEKB accelerator control system will be presented.

At the light source BESSY II numerous experiments as well as machine development studies benefit from a very flexible and stable fill pattern: standard operation mode comprises a multibunch train for the average users, a purity controlled high current camshaft bunch in a variable length ion clearing gap for pump/probe experiments and a mechanical pulse picking chopper, three high current bunches for femto second slicing opposite to the gap and a specific bunch close to the end of the ion clearing gap for resonant excitation pulse picking. The fill pattern generator and control software is based on a state machine. It controls the full chain from gun timing, linac pulse trains, injection and extraction elements as well as next shot predictions allowing triggering the next DAQ cycle. Architecture and interplay of the software components as well as implemented functionality with respect to hardware control, performance surveillance and reasoning of next actions, radiation protection requirements are described.

PID (Proportional, integral and derivative) is the most used feedback control algorithm in the process control industry. Despite its age, its simplicity in terms of deployment and its efficiency on most of industrial processes allow this technique to still have a bright future. One of the biggest challenges in using PID control is to find its parameters, the so-called tuning of the controller. This may be a complex problem as it mostly depends on the dynamics of the process being controlled. In this paper we propose a tool that is able to provide the engineers a set of PID parameters in an automated way. Several auto-tuning methods, both in open and close loop, are selectable and others can be added as the tool is designed to be flexible. The tool is fully integrated in the UNICOS framework and can be used to tune multiple controllers at the same time.

This paper describes the optimization work carried out to improve the performance of the LNLS UVX fast orbit feedback system. Black-box system identification techniques were applied to model the dynamic behavior of BPM electronics, orbit correctors, communication networks and vacuum chamber eddy currents. Due to the heterogeneity on the dynamic responses among several units of those subsystems, as well as variations on the static response matrix due to accelerator optics changes during operation, robust control techniques were employed to achieve appropriate closed-loop performance and robustness.

The Free-Electron Laser in Hamburg (FLASH) is a user facility delivering femtosecond short radiation pulses in the wavelength range between 4.2 and 45 nm using the SASE principle. The tests performed in the last few years have shown that two FLASH undulator beamlines can deliver FEL radiation simultaneously to users with a large variety of parameters such as radiation wavelength, pulse duration, intra-bunch spacing etc. FLASH has two injector lasers on the cathode of the gun to deliver different bunch trains with different charges, needed for different bunch lengths. Because the compression settings depend on the charge of bunches the low level RF system needs to be able to supply different compression for both beamlines. The functionality of the controller has been extended to provide intra-pulse amplitude and phase changes while maintaining the RF field amplitude and the phase stability requirements. The RF parameter adjustment and tuning for RF gun and accelerating modules can be done independently for both laser systems. Having different amplitudes and phases within the RF pulse in several RF stations simultaneous lasing of both systems has been demonstrated.

IT Department of Synchrotron SOLEIL* is structured along of a team of software developers responsible for the development and maintenance of all software from hardware controls up to supervision applications. With a very heterogonous environment such as, several software languages, strongly coupled components and an increasing number of releases, it has become mandatory to standardize the entire development process through a 'Continuous Delivery approach'; making it easy to release and deploy on time at any time. We achieved our objectives by building up a Continuous Delivery system around two aspects, Deployment Pipeline** and DevOps***. A deployment pipeline is achievable by extensively automating all stages of the delivery process (the continuous integration of software, the binaries build and the integration tests). Another key point of Continuous Delivery is also a close collaboration between software developers and system administrators, often known as the DevOps movement. This paper details the feedbacks on this Continuous Delivery approach has been adopted, modifying daily development team life and give an overview of the future steps.

The National Ignition Facility (NIF) is the world's largest and most energetic laser experimental facility with 192 beams capable of delivering 1.8 megajoules of 500-terawatt ultraviolet laser energy. The energy, temperatures and pressures capable of being generated allow scientists the ability to generate conditions similar to the center of the sun and explore physics of planetary interiors, supernovae, black holes and thermonuclear burn. NIF has transitioned to a 24x7 operational facility and in the past year significant focus has been placed on increasing the volume of experimental shots capable of being conducted so as to satisfy the demand from the wide range of user groups. The goal for the current fiscal year is a shot rate of 300 (> 50% increase over the previous year), increasing to a sustainable rate of 400 the year after. The primary focus areas to achieve these increases are; making more shot time available, improvements in experiment scheduling, and reducing the duration of a shot cycle. This paper will discuss the control system improvements implemented and planned to reduce the shot cycle duration and the systematic approaches taken to identify and prioritize them.

At Alba, the Controls Section provides the software that is needed to operate the accelerators, the beamlines and the peripheral laboratories. It covers a wide range of areas or subsystems like vacuum, motion, data acquisition and analysis, graphical interfaces, or archiving. Since the installation and commissioning phases, we have been producing the software solutions mostly in single-developer projects based on the personal criteria. This organization scheme allowed each control engineer to gain the expertise in particular areas by being the unit contact responsible to develop and deliver products. In order to enrich the designs and improve the quality of solutions we have grouped the engineers in teams. The hierarchy of the product backlogs, represents the desired features and the known defects in a transparent way. Instead of planning the whole project upfront, we try to design the products incrementally and develop them in short iterations mitigating the risk of not satisfying the emerging user requirements. This paper describes the introduction of the Scrum framework as the product development strategy in a service oriented organization like the Computing Division at Alba*.

For operation of the three undulator systems of the European XFEL, a total of 91 undulators are needed and have been produced. For production, magnetic measurements, tuning and commissioning of these devices only two years were foreseen by the project schedule. For these purposes, automated and optimized procedures were needed to accomplish a number of workflows, time-consuming adjustments and commissioning tasks. We created several automation programs which allowed us to reduce the time spent on the commissioning of the control system by an order of magnitude.

The Square Kilometre Array (SKA) project is currently in the Pre-construction Phase. During this phase, the telescope subsystems are being designed. The Telescope Manager (TM) is a supervisory control and monitoring subsystem in each of the two radio telescopes of the SKA (SKA1-Low and SKA1-Mid). The TM interfaces with a number of diverse telescope subsystems. Interaction between TM and these subsystems is a major source of requirements for the TM. Careful management of TM external interfaces is therefore important. This discussion is a case study of TM interface management. Firstly, how system architectural design aspects like separation of concerns in the control hierarchy reduce telescope complexity with regards to interfaces is discussed. Secondly, the standardisation approach for monitoring and control interfaces to facilitate early elicitation of interface requirements for the TM, and to manage the diversity of interfacing subsystems is discussed. Thirdly, the relations between interface definition and requirements analysis activities, using SysML representations as an example is discussed.

This paper report about a control system for a dedicated accelerator for SACLA wide-band beam line (BL1), requirements, construction strategies, and present status. At the upgrade plan of SACLA BL1, it was decided to move SCSS test accelerator, which operated from 2005 to 2013, to the upstream of the BL1 in the undulator hall. The control system of the accelerator had to be operated seamlessly with SACLA, to reuse old components as much as possible, and to avoid stopping SACLA user experiments during the start up. The system was constructed with MADOCA which is already used at SACLA. In the control components, VME optical DIO cards and chassis for magnet power supplies were reused after cleaning and checking that there was no degradation of quality. The RF conditioning of the accelerator was started in in October 2014, while SACLA user experiments were going on. A data collection system was prepared, myCC, having a MADOCA compatible interface and an independent database from SACLA. It enabled efficient start up and after enough debugging, the data collection was successfully merged to SACLA in January 2015. Beam commissioning of the accelerator is planned for autumn 2015.

The ALMA software is a large collection of modules, which implements the functionality needed for the observatory day-to-day operations. The main ALMA software components include: array/antenna control/correlator, submission/processing of science proposals, telescope calibration and data archiving. The implementation of new features and improvements for every software subsystem must be coordinated by considering developers schedule, observatory milestones and testing resources available to verify new software. This paper describes the software delivery process adopted by ALMA since the construction phase and its evolution until these days. It also presents the acceptance procedure implemented by the observatory for validating the software used for science operations. Main roles of the software delivery and acceptance processes are mentioned on this paper by including their responsibility at the different development and testing phases. Finally, some ideas are presented about how the model should change in the near future by considering the operational reality of ALMA Observatory.

SSC-LINAC control system is based on EPICS architecture. The sub control system of digital power supplies is a kind of IOC send and receive custom command via Ethernet and TCP/IP protocol. The old IOC is designed to use period scan mode IOC, and there are so many digital power supplies, that we can't make sure every connect condition of digital power supply is fine. IOC must wait a long time if one of them can't connect correctly and other digital power supply's PV may also be blocked. An IOC that uses interrupt driven mode to avoid the shortcoming was designed. This will be described in this paper.

The MCOR-12[Magnet Corrector] is a 16-channel modular architecture, precision magnet driver, capable of providing bipolar output currents in the range from 12A to +12A. A single, unregulated bulk power supply provides the main DC power for the entire crate. Currently the MCORs have a 1000ppm regulation on the B-field. The MCOR controller card upgrades, existing LCLS-I and future LCLS-II needed, controls for Magnet Corrector Power Supplies. The project shifts the existing functionality of the VME based DAC and SAM and an Allen Bradley PLC into a new slot-0 card residing in the MCOR chassis. Elimination of the VME crate and the PLC will free up rack space to be used in future. The new interface card has a long term stability of 100 ppm and monitors ground fault currents and various other interlocks for the MCOR power supplies. The controller can interface to EPICS Channel Access and Fast Feedback system at SLAC using two Gigabit Ethernet ports and has an FPGA based EVR for getting 'time stamps' from the Event Generator system at SLAC. The EPICS control system along with embedded diagnostic features will allow for enhanced remote control and monitoring of the power supplies.

The Renovation of the CERN Controls Configuration Service

103

L. Burdzanowski, C. Roderick
CERN, Geneva, Switzerland

The Controls Configuration Service (CCS) is a key component in CERN's data driven accelerator Control System. Based around a central database, the service also provides a range of client APIs and user interfaces - enabling configuration of controls for CERN's accelerator complex. The service has existed for 35 years (29 based on Oracle DBMS). There has been substantial evolution of the CCS over time to cater for changing requirements and technology advances. Inevitably this has led to increases in CCS complexity and an accumulation of technical debt. These two aspects combined have a negative impact on the flexibility and maintainability of the CCS, leading to a potential bottleneck for Control System evolution. This paper describes on-going renovation efforts (started mid-2014) to tackle the aforementioned issues, whilst ensuring overall system stability. In particular, this paper covers architectural changes, the agile development process in place - bringing users close to the development cycle, and the deterministic approach used to treat technical debt. Collectively these efforts are leading towards a successful renovation of a core element of the Control System.

SLAC's Low Level Radio Frequency (LLRF) controls software for the S-Band deflecting structures needed to be upgraded significantly when a new X-Band transverse deflecting cavity (XTCAV) was installed downstream of the LCLS undulators in Spring 2013 to assist in FEL diagnostics such as characterizing the temporal profile of X-ray pulses that vary shot-to-shot. The unique location of the XTCAV in the beamline posed several challenges. A new design of the Modulator and Klystron control Support Unit (MKSU-II) for interlocking was added at the XTCAV controls station that required new software development. The timing setup was also different from the rest of the Linac. This paper outlines the LLRF controls layout for the XTCAV and discusses the manner in which the challenges were addressed. XTCAV has now become a successful tool for gathering data that enables reconstruction of X-ray FEL power profiles with greater resolution.

SLAC, Menlo Park, California, USA

Wire scanners are a main diagnostic tool for transverse beam size and emittance measurements at LCLS. The original SLAC wire scanners were not optimized for speed (taking minutes to scan), and can't perform at the desired level of position resolution necessary for measuring LCLS' small beam size. A new fast wire scanner, based on a dc linear servo motor, has been designed and installed in the LCLS. The new fast wire scanner has several advantages over the original wire scanner: scan times are reduced from minutes to seconds while minimizing wire vibrations. Rather than counting open-loop step pulses, the new fast wire scanner uses real time position capture for beam synchronous sampling of the wire position, enhancing beam profile accuracy.

The first long shutdown of the Large Hadron Collider (LS1, 2013-2015) provided an opportunity for significant upgrades of the detector control and safety systems of the CMS Electromagnetic Calorimeter. A thorough evaluation was undertaken, building upon experience acquired during several years of detector operations. Substantial improvements were made to the monitoring systems in order to extend readout ranges and provide improved monitoring precision and data reliability. Additional remotely controlled hardware devices and automatic software routines were implemented to optimize the detector recovery time in the case of failures. The safety system was prepared in order to guarantee full support for both commercial off-the-shelf and custom hardware components throughout the next accelerator running period. The software applications were modified to operate on redundant host servers, to fulfil new requirements of the experiment. User interface extensions were also added to provide a more complete overview of the control system. This paper summarises the motivation, implementation and validation of the major improvements made to the hardware and software components during the LS1 and the early data-taking period of LHC Run 2.

CERN, Geneva, Switzerland

Almost 200 controls applications, in domains like LHC magnet protection, cryogenics and vacuum systems, cooling-and-ventilation or electrical network supervision, have been developed and are currently maintained by the CERN Industrial Controls Group in close collaboration with several equipment groups. The supervision layer of these systems is based on the same technologies as 400 other systems running in the LHC Experiments (e.g. WinCC Open Architecture, Oracle). During the last two-year LHC Long Shutdown 1, the 200 systems have been successfully migrated from a file-based archiver to a centralized infrastructure based on Oracle databases. This migration has homogenized the archiving chain for all CERN systems, and at the same time has presented a number of additional challenges. The paper presents the design, the necessary optimizations and the migration process that allowed us to meet unprecedented data-archiving rates (unachievable for the previously used system), and liaise with the existing long-term storage system (LHC LoggingDB) to assure data-continuity.

GSI, Darmstadt, Germany

In preparation of FAIR, several well-established beam instrumentation systems of the GSI heavy-ion synchrotron SIS18 and its connected high-energy beam transfer lines (HEBT) have to be modernized. In this contribution, the data acquisition upgrade of particle detectors such as ion chambers and plastic scintillators is described. This covers the replacement of an outdated custom-built readout- and control hardware by modern FMC (FPGA mezzanine card) based I/O hardware, new multi-channel high voltage power supplies and a new data acquisition system (DAQ) for the VME based scalers. The latter will replace the old Kylix-based ABLASS software by LASSIE (Large Analog Signal and Scaling Information Environment) to fit into the new FAIR control system concept. LASSIE is based on FESA (Front End Software Architecture). FESA was originally developed by CERN and enhanced by GSI-specific modifications. Furthermore, the new particle detector DAQ will be able to take full advantage of the new FAIR timing system which is based on the White Rabbit protocol.

SAGA, Tosu, Japan

The update of control system at the SAGA Light Source storage ring power supplies is in progress for improving the ramp-up speed (from 255 MeV to 1.4 GeV) and for easily changing the stored beam energy. By replacing the CPU unit of PLC used for control of the power supplies, the ramp-up time was reduced from 4 to 2 minutes in a test bench prepared for the upgrade system. Currently the allowable beam energy is restricted to some fixed values in the ramp-up operation due to the original specification of the PLC ladder program. To operate storage ring at an arbitrary energy, the algorism used in the PLC program has been improvement. Energy dependent measurements (betatron-tune, beam size, and beam half-lifetime) will be carried out by using the updated control system. The upper layer of the control system using the National Instrument LabVIEW and ActiveXCA was also reconstructed for flexible GUI.

D. Maier-Manojlovic
PSI, Villigen PSI, Switzerland

EtherCAT bus and interface are widely used for external module and device control in accelerator environments at PSI, ranging from undulator communication, over basic I/O control to Machine Protection System for the new SwissFEL accelerator. A new combined EPICS/Linux driver has been developed at PSI, to allow for simple and mostly automatic setup of various EtherCAT configurations. The new driver is capable of automatic scanning of the existing device and module layout, followed by self-configuration and finally autonomous operation of the EtherCAT bus real-time loop. If additional configuration is needed, the driver offers both user- and kernel-space APIs, as well as the command line interface for fast configuration or reading/writing the module entries. The EtherCAT modules and their data objects (entries) are completely exposed by the driver, with each entry corresponding to a virtual file in the Linux procfs file system. This way, any user application can read or write the EtherCAT entries in a simple manner, even without using any of the supplied APIs. Finally, the driver offers EPICS interface with automatic template generation from the scanned EtherCAT configuration.

SLAC, Menlo Park, California, USA

As facilities age and evolve, constant effort is needed in upgrading control system infrastructure; this applies to all aspects of an accelerator facility. Portions of the Personnel Protection System of the Linac Coherent Light Source are still relying on a legacy, relay-based Safety System. An upgrade is underway to modernize these systems using Siemens S7-300 Safety PLCs and Pilz PNOZMulti programmable controllers. The upgrade will be rolled out over multiple years requiring the implementation to be fully compatible with adjacent legacy system while setting the foundation for the new generation system. The solution relies on a modularized safety system which can be deployed in a short time (1 month) while being flexible enough to adapt to the evolving needs over the next 20 years.

T2K is a long-baseline neutrino oscillation experiment at J-PARC in Japan. High intensity neutrino/antineutrino beam is generated and propagates 295km to Super-Kamiokande. High intensity proton beam, 350 kW in May 2015, is extracted from Main Ring synchrotron, guided through a primary proton beamline to a graphite target using normal-conducting (NC) magnets and super-conducting combined-function magnets. In October 2014, we replaced all the power supplies (PSs) for NC magnets with newly developed PSs. We also developed new control system based on EPICS and PLCs, putting emphasis on the safe operation of power supplies, and integrated it into the existing interlock system. Consequently the latency time for the interlock system was improved. We report the actual implementation and operation results of these developments.

LCLS is a facility for generation of very short duration, highly intense x-ray pulses which requires an extremely reliable photocathode electron source. In order to maintain high up-time (>95%) for the experimenters, operations rely on a maintenance program for active laser components as well as on built-in redundancy in case of failure. To accomplish this, a duplicate laser system was installed, allowing for quick swap between the active system and the spare in the event of a malfunction or for planned maintenance. As an added bonus, this redundant system provides additional possibilities for science as both laser systems can also be run to the cathode simultaneously to create multiple particle bunches. Diagnostics were put in place to maintain both special and temporal overlap and allow for the fast switching between systems by operations personnel while still remaining within the safety envelope. This was done for both the primary UV drive laser as well as the secondary IR "heater" laser. This paper describes the installation challenges and design architecture for this backup laser system.

SESAME is a 2.5 GeV synchrotron light source under construction in Allan, Jordan. The control system of SESAME is based on EPICS and CSS. Various developments in EPICS drivers, clients, software tools and hardware have been done. This paper will present some of the main achievements: new linux-x86 EPICS drivers and soft IOCS developed for the Micro-Research Finland event timing system replacing the VME/VxWorks-based drivers; new EPICS drivers and clients developed for the Basler GigE cameras; an IOC deployment and management driver developed to monitor the numerous virtual machines running the soft IOCs, and to ease deployment of updates to these IOCs; an automated EPICS checking tool developed to aid in the review, validation and application of the in-house rules for all record databases; a new EPICS record type (mbbi2) developed to provide alarm features missing from the multibit binary records found in the base distribution of EPICS; and a test of feasibility for replacing serial terminal servers with low-cost computers.

Toward SuperKEKB project, the injector linac upgrade is ongoing for aiming at the stable electron/positron beam operation with low emittance and high intensity bunch charge. To obtain such high quality beam, we have being commissioning many newly developed subsystems including a low emittance photocathode rf gun since October of 2013. Eventually, we will perform the simultaneous top-up for the four independent storage rings including two light sources. The stable beam operation as long as possible is desired since the prospective physics results strongly depends on the reliability and availability of accelerator operation. Since the middle stage of KEKB project, the injector linac control system has been gradually transferred to the EPICS based one from the in-house system based on RPC. We are expanding the existing control system for the newly installed devices like a network attached power supply, timing jitter monitoring system, and so on. In addition, many commissioning tools are now under development to accelerate the high quality beam development. In this paper, we will describe the present status of injector linac control system and future plan in detail.

173

D. Schirmer, A. Althaus, F.H. Bahnsen
DELTA, Dortmund, Germany

Increasing demands, mandatory replacement of obsolete controls equipment as well as the introduction of new soft- and hardware technologies with short innovation cycles are some of the reasons why control systems need to be revised continuously. Thus, also at the EPICS-based DELTA control system, several projects have been tackled in recent years: (1) Embedding the new CHG-based short-pulse facility for VUV and THz radiation required, for example, the integration of IP-cameras, Raspberry-Pi PCs and EtherCat/TwinCat wired I/O-devices. (2) The request for a staff-free control room led to the programming of new web applications using Python and the Django framework. This development resulted in a web-based interlock system that can be run, amongst others, on Android-based mobile devices. (3) The virtualization infrastructure for server consolidation has been extended and migrated from XEN to the kernel based KVM approach. (4) I/O-units which were connected via conventional fieldbus systems (CAN, GPIB, RS-232/485), are now gradually replaced by TCP/IP-controlled devices. This paper describes details of these upgrades and further new developments.

For years, accelerator operators at the SLAC National Accelerator Laboratory (SLAC) have favored hardware knobs in the control room for accelerator tuning. Hardware knobs provide a tactile, intuitive, and efficient means of adjusting devices. The evolution of separate control systems for different accelerator facilities at SLAC has resulted in multiple flavors of knob hardware and software. To improve efficiency, space usage, and ease of use, the knob systems have been upgraded and integrated.

The WinCC Open Architecture (OA) SCADA package and the controls frameworks (UNICOS, JCOP) developed at CERN were successfully used to implement many critical control systems at CERN. In the recent years, the supervision and the controls of many technical infrastructure systems (electrical distribution, cooling and ventilation, etc.) were rewritten to use this standard environment. Operators at the Technical Infrastructure desk, who monitor these systems, are forced to continuously switch between the applications that allow them to monitor these infrastructure systems. The Technical Infrastructure Portal (TIP) was designed and is being developed to provide centralized access to all technical infrastructure systems and extend their functionality by linking to a powerful localization system based on GIS. Furthermore, it provides an environment for operators to develop views that aggregate data from different sources, like cooling and electricity.

The Keck telescopes, located at one of the world's premier sites for astronomy, were the first of a new generation of very large ground-based optical/infrared telescopes with the first Keck telescope beginning science operations in May of 1993, and the second in October of 1996. The components of the telescopes and control systems are more than 15 years old. The upgrade to the control systems of the telescopes consists of mechanical, electrical, software and network components with the overall goals of improving performance, increasing reliability, addressing serious obsolescence issues and providing a knowledge refresh. This paper is a continuation of one published at the 2013 conference and will describe the current status of the control systems upgrade. It will detail the implementation and testing for the Keck II telescope, including successes and challenges met to date. Transitioning to nighttime operations will be discussed, as will implementation on the Keck I telescope.

At LNL it is being carried out an upgrade campaign of the control systems of the accelerator complex. The two main goals are standardization of hardware and software and system interoperability. EPICS has been chosen as the standard framework for developing new control systems; this will address software standardization and system interoperability. In order to achieve hardware standardization, a new EPICS IOC is under development, which will become a basic construction block for all future control systems. The COM (Computer-on-Modules) from factor has been chosen as the hardware platform for the IOC, along with the peripheral devices needed for developing all the foreseen control system at LNL. Prototypes of this IOC has been developed using ADLINK's Type 6 COM Express modules on generic carrier boards with DIO, ADC and DAC expansion boards. These prototypes have been tested under typical applications at LNL in order to validate the hardware platform choice. Experimental results show that the performance of the IOC in terms of effective resolution (ENOB and bias error), sample rates and CPU usage is suitable for satisfying the requirements of the control systems.

Funding: This work has been partially funded by the Spanish Ministry of Economy and Competitiveness, under projects OPTIMHAC FIS2013-40860-R and IFMIF-EVEDA II. Ref: AIC-A-2011-0654.
Linear IFMIF* Prototype Accelerator (LIPAc), Rokkasho, Japan, comprises a succession of devices and systems that accelerate a deuteron beam up to 9 MeV with a current of 125 mA, generating a power of 1.125 MW, and transport it up to a beam dump. The beam power becomes critical from the point of view of losses; even tiny losses must be avoided. This fact, and the complexity of the accelerator operation, requires a coherent strategy when designing, commissioning and optimizing the accelerator control system, specifically focused in the control systems of the Medium Energy Beam Transport (MEBT) and the Diagnostic Plate (DP, a movable set of diagnostics). Both systems are essential to validate the performance of the accelerator and particularly the ion source, Radio Frequency (RF) and Radio Frequency Quadrupole (RFQ) systems. This contribution will describe the recent advances in the control architectures and the EPICS based developments achieved in MEBT for the motion control of bunchers and scrapers, control of the power supplies in quadrupoles and steerers, and refrigeration and vacuum. Besides, control of fluorescence profile monitors (FPMs) in the D-Plate is displayed.
*IFMIF, the International Fusion Materials Irradiation Facility, is an accelerator-based neutron source that will use Li (d, xn) reactions to generate a flux of neutrons with a broad peak at 14 MeV.

SOLEIL is a third generation synchrotron radiation source located near Paris in France. REVOLUTION (REconsider Various contrOLler for yoUr motion) is the motion controller upgrade project currently in progress at SOLEIL. It was initiated to maintain the facility operations by addressing the risk of hardware obsolescence in motion control but at the same time making room for complex applications requirements to face new high performance challenges. In order to achieve these considerations, SOLEIL's strategy move was to go from a single controller for all applications to two motion controllers. A first Controller GALIL DMC-4183 was chosen to succeed the previous version DMC-2182. Both controllers can be integrated in the existing architecture with little hardware and software adaptation enabling full compatibility with the existing architecture. A second controller, Delta Tau Power Brick, has been selected as a HIGH PERFORMANCE solution providing advanced functionality. The CLASSIC controller upgrade is about to be completed and the integration of Power Brick into the SOLEIL control system is ongoing. The system complexity is abstracted by embedding processing functions into low-level code and giving end-users a simple high-level interface. The work done to structure the interfacing and standardization of the controller are detailed in this paper.

Instrument control at ISIS is in the process of migrating from a mainly locally developed system to an EPICS based system. The new control system, called IBEX, was initially used during commissioning of a new instrument prior to a long maintenance shutdown. This first usage has provided valuable feedback and significant progress has been made on enhancing the system during the facility maintenance period in preparation for the move onto production use. Areas that will be of particular interest to scientists in the future will be linking feedback from live data analysis with instrument control and also providing a simple and powerful scripting interface for facility users. In this paper we will cover the architecture and design of the new control system, our choices of technologies, how the system has evolved following initial use, and our plans for moving forward.

209

MAX-lab, Lund, Sweden

The MAX IV synchrotron radiation facility is currently being constructed in Lund, Sweden. A linear accelerator serves as the injector for the two storage rings and also as the source of short X ray pulses, in which mode it will operate with a 100Hz repetition rate. The controls system, based on TANGO, is required to collect and archive data from several different types of hardware at up to this 100Hz frequency. These data are used for example in offline beam diagnostics, for which they must be associated to a unique electron bunch number. To meet these requirements, the timing performance of the hardware components have been studied, and a TANGO Fast Archiver device created. The system is currently in the deployment phase and will play an important role in allowing the linac and Short Pulse Facility reach their 100Hz design goal

ELI-ALPS will provide a wide range of attosecond pulses which will be used for performing experiments by international research groups. ELI-ALPS will use the TANGO Controls framework to build up the central control system and to integrate the autonomous subsystems regarding software monitoring and control. Beside a robust central and integrated control system a flexible and dynamic high level environment could be beneficial. The envisioned users will come from diverse fields including chemistry, biology, physics or medicine. Most of the users will not have programming or scripting background. Meanwhile workflow system provides visual programming facilities where the logics can be drawn, which is understandable by the potential users. We have integrated TANGO into the Kepler workflow system because it gives a lot of actors for all natural scientific fields. Moreover it has the potential for running the workflows on HPC or GRID resources. We demonstrated the usability of the development with a beamline simulation. The TANGO-Kepler integration provides an easy-to-use environment for the users therefore it can facilitate e.g. the standardization of measurements protocols as well.

LHCb is one of the four experiments at the LHC accelerator at CERN. For the LHCb upgrade, hundreds of new electronics boards for the central data acquisition and for the front-end readout of the different sub-detectors are being developed. These devices will need to be integrated in the Experiment Control System (ECS) that drives LHCb. Typically, they are controlled via a server running on a PC which allows the communication between the hardware registers and the experiment SCADA (WinCC OA). A set of tools was developed that provide an easy integration of the control and monitoring of the devices in the ECS. The fwHw is a tool that allows the abstraction of the device models into the ECS. Using XML files describing the structure and registers of the devices it creates the necessary model of the hardware as a data structure in the SCADA. It allows then the control and monitoring of the defined registers using their name, without the need to know the details of the hardware behind. The fwHw tool also provides the facility of defining and applying recipes - named sets of configuration parameters which can be used to easily configure the hardware according to specific needs.

Synchronising High-Speed Triggered Image and Meta Data Acquisition for Beamlines

225

N. De Maio, A.P. Bark, T.M. Cobb, J.A. Thompson
DLS, Oxfordshire, United Kingdom

High-speed image acquisition is becoming more and more common on beamlines. As experiments increase in complexity, the need to record parameters related to the environment at the same time increases with them. As a result, conventional systems for combining experimental meta data and images often struggle to deliver at a speed and precision that would be desirable for the experiment. We describe an integrated solution that addresses those needs, overcoming the performance limitations of PV monitoring by combining hardware triggering of an ADC card, coordination of signals in a Zebra box* and three instances of area-Detector streaming to HDF5 data. This solution is expected to be appropriate for frame rates ranging from 30Hz to 1000Hz, with the limiting factor being the maximum speed of the camera. Conceptually, the individual data streams are arranged in pipelines controlled by a master Zebra box, expecting start/stop signals on one end and producing the data collections at the other. This design ensures efficiency on the acquisition side while allowing easy interaction with higher-level applications on the other.

When the FRM-2 neutron source went into operation (2002) and many instruments were moved from the closed-down Jülich reactor to the new facility, it was agreed on a choice of front-end hardware and the TACO middleware from ESRF. To keep up with software standards, it was decided recently to switch to TACO's successor - the TANGO control software. For a unified "user experience", new graphical user interface software "NICOS-2" is being developed by the software group at FRM2. While general semantics of TACO and TANGO don't look very different at a first glance, and adaption of device servers seemed to be straightforward at first, various problems in practical operation were found. The problems were due to differences in state handling, timing behavior and error reporting. These problems, and the changes that had to be made to ensure reliable operation again, will be described.

DNS is a time of flight neutron spectrometer with polarization analysis that experienced a major upgrade in 2014 and 2015. During the upgrade DNS was equipped with new electronics and a new control and data acquisition system, including a transition from the existing TACO system to its successor TANGO. On the client side the NICOS software developed at FRM II is used for the implementation of measurement operations and user interface. The design of the new control and data acquisition system is presented and the lessons learned by the introduction of TANGO are reported.

MAX IV Laboratory, a synchrotron facility in Lund, has selected TANGO as the control system framework for the entire facility. On the beamlines that are being built the Python-based SCADA (supervisory control and data acquisition) system Sardana will be used for experimental control. SPECIES, one out of eight new soft X-ray beamlines, is used as a test bench for evaluating the chosen standards. Sardana is used to control the energy setting of the PGM (plane grating monochromator) as well as to provide macros and other utilities for the user. Generic Taurus GUIs and a SVG-synoptic give the user a way to interact with the control system and display relevant information. The standardized graphical interfaces give a familiar look and feel across the entire facility. All motorized axes are controlled with the IcePAP motion controller. For the axes of the PGM, the IcePAP driver operates in hardware closed loop. Special care is taken in order to avoid slow and inaccurate movements of the PGM energy due to the non-linear relationship between the motors and the angular encoders.

Synchronous ramping of an assembly of magnets is critical for operation of beam in an accelerator. Magnet currents must remain within the operational limits to avoid dis-alignment of electron beam. In order to comply with the design specifications of ERL and ELENS project , two different software control mechanisms have been developed. The ramp profile is automated and maintained by tracking current in all dipole magnets at ERL and superconducting solenoid magnets at ELENS. This mechanism speeds up operations and adds a level of protection. The purpose of this application is to reduce unnecessary interlocks of the personnel protection system. This paper will describe the power supply arrangement, communication mechanism and the state machine algorithm used for feedback and control. A report on operating experience will be presented.

Funding: SKA South Africa, National Research Foundation of South Africa, Department of Science and Technology.
The 64-dish MeerKAT radio telescope, currently under construction, comprises several loosely coupled independent subsystems, requiring a higher level Control and Monitoring (CAM) system to operate as a coherent instrument. Many control-system architectures are bus-like, clients directly \mbox{receiving} monitoring points from Input/Output Controllers; instead a multi-layer architecture based on point-to-point Karoo Array Telescope Control Protocol (KATCP) connections is used for MeerKAT. Clients (e.g. operators or scientists) only communicate directly with the outer layer of the telescope; only telescope interactions required for the given role are exposed to the user. The layers, interconnections, and how this architecture is used to meet telescope system requirements are described. Requirements include: Independently controllable telescope subsets; dynamically allocating telescope resources to individual users or observations, preventing the control of resources not allocated to them; commensal observations sharing resources; automatic detection of, and responses to, system-level alarm events; high level operator controls and health displays; automatic execution of scheduled observations.

The increased brilliance of state-of-the-art Synchrotron radiation sources and Free Electron Lasers require imaging detectors capable of taking advantage of these light source facilities. The PERCIVAL ("Pixelated Energy Resolving CMOS Imager, Versatile and Large") detector is being developed in collaboration between DESY, Elettra Sincrotrone Trieste, Diamond Light Source and Pohang Accelerator Laboratory. It is a CMOS detector targeting soft X-rays < 1 KeV, with a high resolution of up to 13 M pixels reading out at 120 Hz, producing a challenging data rate of 6 GB/s. The controls and data acquisition system will include a SDK to allow integration with third party control systems like Tango and DOOCS; an EPICS areaDetector driver will be included by default. It will make use of parallel readout to keep pace with the data rate, distributing the data over multiple nodes to create a single virtual dataset using the HDF5 file format for its speed advantages in high volumes of regular data. This paper presents the design of the control system software for the Percival detector, an update of the current state of the implementation carried out by Diamond Light Source.

In the era of extremely large telescopes (ELT) an adaptive optics (AO) system with artificial guide stars is an essential part of the optics between the source and the instrument. For the Giant Magellan Telescope these guide stars are formed by stimulating emission from Sodium atoms in the atmosphere with lasers launched from the side of the telescope. Moreover, they are resolved by the adaptive optics system so Shack-Hartmann wavefront sensors record elongated spots. Cost effective proof-of-concept systems for investigating control algorithms must be built for deployment in the lab or on small telescopes. We present a hardware and software system that mimics the propagation of a single laser guide star (LGS) through the Earth's atmosphere and the optics of the Giant Magellan Telescope, using source motion and brightness modulation to simulate the source extension. A service oriented architecture allows adaptive optics scientists to construct images from different LGS asterisms and build non-real-time closed-loop control systems in high-level languages.

Funding: Work supported by BMBF and Land Berlin.
Full stability potential of orbit and bunch-by-bunch-feedback controlled top-up operation becomes available to the experimental users only if the remaining slow drifts of essential operational parameters are properly compensated. At the light source BESSY II these are the transversal tunes as well as the path length and energy. These compensations are realized using feedback control loops together with supervising state machines. Key to the tune control is a multi-source tune determination algorithm. For the path length correction empirical findings are utilized. All involved software systems and data-paths are sketched.

The piezo based control of the superconducting cavity tuning has been under the development over last years. Automated compensation of Lorentz force detuning of FLASH and European X-FEL resonators allowed to maintain cavities in resonance operation even for high acceleration gradients (in range of 30 MV/m). It should be emphasized that cavity resonance control consists of two independent subsystems. First of all the slow motor tuner based system can be used for slow, wide range mechanical tuning (range of hundreds of kHz). Additionally the piezo tuning system allows for fine, dynamic compensation in a range of ~1 kHz. In mentioned pulse mode experiments (like FLASH), the piezo regulation budget should be preserved for in-pulse detuning control. In order to maintain optimal cavity frequency adjustment capabilities slow motor tuners should automatically act on the static detuning component at the same time. This paper presents work concerning development, implementation and evaluation of automatic superconducting cavity frequency control towards piezo range optimization. FLASH and X-FEL dedicated cavities tuning control experiences are also summarized.

NICA (Nuclotron based Ion Collider fAcility) is an accelerator complex, which is being built in JINR (Dubna, Russia). The system described in this paper is controlling the RF stations of booster, the first element of the NICA complex. The two devices are parts of the Control System: Intellectual Controller and Tester module. The first one is designed for precise measurement of magnetic field, generation of the acceleration frequency in accordance with measured field and control RF power and pre-amplifiers. Intellectual Controller is a real-time feed-forward system with 20 ums loop time. It is based on ARM microcontroller and bare-metal control programs are used to reach maximum performance. Approaches that were used to achieve maximum performance are elaborated and presented in this paper. The second part of system - Tester is a simulator for tuning and checking the RF stations before start of operations or in absence of real accelerator. The achieved accuracy in chain 'magnetic field' - 'acceleration frequency' is better than 5*10^-5. Plans on feedback incorporation to stabilize ion beam behavior via frequency and phase tuning are discussed.

For a low emittance light source, beam orbit motion needs to be controlled within submicron for obtaining a high quality light. Magnets vibration especially quadruples will be one of the main sources to destroy the beam stability. In order to study the relationship between vibration and beam motion, it is highly desirable to use a synchronous data acquisition system which integrates measurement of vibration and beam position monitor systems especially for the coherence analysis. For a larger vibration such as earthquakes are also deleterious to beam stability or even make the beam trip due to the quench of superconducting RF cavity. A data acquisition system integrated with an earthquake detector is also quite necessary to show and archive the data on the control system. The data acquisition systems of vibration and earthquake measurement system are summarized in this report. The relationship between the beam motion and magnets vibration will also study here.

Control of Fast-Pulsed Power Converters at CERN Using a Function Generator/Controller

281

R. Murillo-Garcia, Q. King, M. Magrans de Abril
CERN, Geneva, Switzerland

The electrical power converter group at CERN is responsible for the design of fast-pulsed power converters. These generate a flat-top pulse of the order of a few milliseconds. Control of these power converters is orchestrated by an embedded computer, known as the Function Generator/Controller (FGC). The FGC is the main component in the so-called RegFGC3 chassis, which also houses a variety of purpose-built cards. Ensuring the generation of the pulse at a precise moment, typically when the beam passes, is paramount to the correct behaviour of the accelerator. To that end, the timing distribution and posterior handling by the FGC must be well defined. Also important is the ability to provide operational feedback, and to configure the FGC, the converter, and the pulse characteristics. This paper presents an overview of the system architecture as well as the results obtained during the commissioning of this control solution in CERN's new Linac4.

The measured bending field of the CERN Proton Synchrotron (PS) is received in real-time by the longitudinal beam control system and converted into the revolution frequency used as set-point for beam phase and radial loops. With the renovation of the bending field measurement system the transmission technique is changed from a differential sequence of pulses, the so-called B-train, to a stream of Ethernet frames based on the White Rabbit protocol. The packets contain field, its derivative and auxiliary information. A new frequency program for the conversion of the bending field into the revolution frequency, depending also on parameters like radius of the accelerator and the particle type, has been developed. Instead of storing large conversion tables from field to frequency for fixed parameters, the frequencies are directly calculated in programmable logic (FPGA). In order to reduce development time and keep flexibility, the conversion is processed in real-time in the FPGA using Xilinx floating-point primitives mapped by a higher level tool Simulink System Generator. Commissioning with beam of the new frequency program in the PS is progressing.

The Accelerator R&D Group within the Argonne National Laboratory (ANL) Physics Division maintains a beam dynamics model named TRACK. This simulation code has the potential to assist operators in visualizing key performance parameters of the Argonne Tandem Linear Accelerating System (ATLAS). By having real-time access to visual and animated models of the particle beam transverse and longitudinal phase spaces, operators can more quickly iterate to a final machine tune. However, this effort requires a seamless integration into the control system, both to extract initial run-time information from the accelerator, and to present the simulation results back to the users. This paper presents efforts to pre-process, batch execute, and visualize TRACK particle beam physics simulations in real-time via the ATLAS Control System.

DLS, Oxfordshire, United Kingdom

We describe the detailed internal architecture of the Transverse Multi-Bunch Feedback processor used at Diamond for control of multi-bunch instabilities and measurement of betatron tunes. Bunch by bunch selectable control over feedback filters, gain and excitation allows fine control over feedback, allowing for example the single bunch in a hybrid or camshaft fill pattern to be controlled independently from the bunch train. It is also possible to excite all bunches at a single frequency while simultaneously sweeping the excitation for tune measurement of a few selected bunches. The single frequency excitation has been used for continuous measurement of the beta-function. A simple programmable event sequencer provides support for up to 7 steps of programmable sweeps and changes to feedback and excitation, allowing a variety of complex and precisely timed beam characterisation experiments including grow-damp measurements in unstable conditions and programmed bunch cleaning. Finally input and output compensation filters allow for correction of front end and amplifier phasing at higher frequencies.

Synchrotron SOLEIL and Diamond Light Source are two third generation light sources located respectively in France and the UK. In the past 5 years, both facilities separately developed their own platform permitting encoder processing to synchronize motion systems and acquisition during experiments, SPIETBOX by SOLEIL and Zebra by Diamond. New operational requirements for simultaneous and multi-technique scanning, and support of multiple encoder standards have been identified by both institutes. In order to address these a collaborative project has been initiated between SOLEIL and Diamond to realize a new 'Position and Acquisition' processing platform, called PandA. The PandA project addresses current systems' limitations in term of obsolescence and need for more processing power. Its design is going to be a 1U standalone system powered by a Xilinx Zynq SoC to implement a configurable set of logic functionalities. It will provide a flexible and open solution to interface different third party hardware (detectors and motion Controllers). This paper details the organization of this collaboration, sharing technical leadership between both institutes and the status of the project.

In the Large Hadron Collider (LHC), over 100 movable collimators are connected to a three-tier control system which moves them to the required settings throughout the operational cycle from injection to collision energy. A dedicated control system was developed to align the collimators to the beam during machine commissioning periods and hence determine operational settings for the active run. During Long Shutdown 1, the control system was upgraded to allow beam-based alignments to be performed using embedded beam position monitors in 18 newly installed collimators as well as beam loss monitors. This paper presents the new collimation controls architecture for LHC Run II along with several modifications in the Java-based application layer.

The European X-Ray Free-Electron Laser (XFEL) will generate extremely short and intense X-ray flashes from the electron beam of a 2.1 km long superconducting linear accelerator. Due to the complexity of the facility and the sheer number of subsystems and components, special emphasis needs to be placed on the automatization of procedures, on the abstraction of machine parameters, and on the development of user-friendly high-level software for the operation of the accelerator. This paper gives an overview of the ongoing work and highlights several new tools and concepts.

NA62 is a fixed target experiment to measure very rare decays of Kaons at CERN Super Proton Synchrotron accelerator. The NA62 experiment line comprises several large detectors installed inside a vacuum vessel with a length of 250 m and an internal diameter of up to 2.8 m. The vacuum installation consists of 170 remote controlled pumps, valves and gauges. The operational specifications of NA62 require a complex vacuum control system: tight interaction between vacuum controllers and detector controllers, including pumping or venting vetoes, and detector start-stop interlocks; most of the valves are interlocked, including the large vacuum sector gate valves; the vacuum devices are driven by 20 logic processes. The vacuum control system is based on commercial Programmable Logical Controllers (Siemens PLC: S7-300 series) and a Supervisory Control And Data Acquisition application (Siemens SCADA: WINCC OA). The control software is built upon the standard framework used in CERN accelerators vacuum, with some specific developments. We describe the controls architecture, and report on the particular requirements and the solutions implemented.

NA62 is the follow-up of the NA48 experiment, in the SPS North Area of CERN, and reuses a large fraction of its detectors and beam line equipment. Still, there are many new vacuum devices in the beam line (including pumps, valves & gauges), which required a thorough modification of the control system and a large number of new controllers, many of which were custom-made. The NA62 vacuum control system is based on the use of PLCs (Programmable Logic Controllers) and SCADA (Supervisory Control and Data Acquisition). The controllers and signal conditioning electronics are accessed from the PLC via a field bus (Profibus); optical fibre is used between surface racks and the underground gallery. The control hardware was completely commissioned during 2014. The nominal pressure levels were attained in all sectors of the experiment. The remote control of all devices and the interlocks were successfully tested. This paper summarizes the architecture of the vacuum control system of NA62, the types of instruments to control, the communication networks, the hardware alarms and the supervisory interface.

For two years (Spring 2013 - Spring 2015), the LHC went through its first long shutdown (LS1). It was mainly motivated by the consolidation of magnet interconnects, to allow operation with 6.5 TeV proton beams. Moreover, around the accelerator complex, many other systems were repaired, consolidated or upgraded, and several new installations came to life. The standardization of vacuum controls has progressed in the injectors, with the renovation of most of their obsolete equipment. In the LHC, many new instruments were added, the signal transmission integrity was improved, and the exposure to radiation was reduced in critical places. Several developments were needed for new equipment types or new operational requirements.

Funding: This project has received funding from the European Union's Seventh Framework Programme for research, technological development and demonstration under grant agreement no 289485.
We have developed a control system configuration tool, which provides an easy-to-use interface for quick configuration of the entire facility. It uses Microsoft Excel as the front-end application and allows the user to quickly generate and deploy IOC configuration (EPICS start-up scripts, alarms and archive configuration) onto IOCs; start, stop and restart IOCs, alarm servers and archive engines, and more. The DCDB tool utilizes a relational database, which stores information about all the elements of the accelerator. The communication between the client, database and IOCs is realized by a REST server written in Python. The key feature of the DCDB tool is that the user does not need to recompile the source code. It is achieved by using a dynamic library loader, which automatically loads and links device support libraries. The DCDB tool is compliant with CODAC (used at ITER and ELI-NP), but can also be used in any other EPICS environment (e.g. it has been customized to work at ESS).

The Italian National Institute for Astrophysics (INAF) manages three radio telescopes: the Medicina and Noto dishes and the newly-built SRT. In order to make their capabilities more valuable to the scientific community, we started the DISCOS (Development of the Italian Single-dish COntrol System) project. DISCOS is implemented according to a distributed Component-Container model and hides to the users the differences among the telescopes by presenting the same user interface and the same data format. The complexity of coping with three heterogeneous instruments was handled designing a software development infrastructure with a wide monolithic codebase (libraries, components and generic interfaces), which is completely shared among the three product lines. This design permits to produce new software components with a minimum effort and to set up the same test suites for all the environments, thus leading to an affordable development and maintenance process. In this paper we illustrate the design strategies and the development techniques used to realize and optimize this common control software. We also provide a description of the project status and future plans.

In the LHC beam pipes and cryostats, the pressure measurement covers a wide range, from 1500 mbar down to 10^-11 mbar and even lower. If vacuum deteriorates, alarm signals are generated and sent to other systems, e.g. cryogenics, accelerating cavities, kicker magnets, and beam interlock. In addition, an unacceptable pressure rise in beam pipes generates interlocks to close the adjacent sector valves, thus isolating the sector, so that the pressure rise does not propagate. This paper describes the measurement chains, the alarms and interlocks logic used in the vacuum control system of the LHC. We analyze the possible signal degradation caused by ionizing radiation or due to cable length, shielding and grounding. The weaknesses of the existing vacuum measurement system are pointed out, and a prospective for improvement of the conditioning electronics is proposed. During the first LHC long shut down, several corrections were applied; the results of the tests after commissioning are also presented.

During the last two years, triggered by the construction of the XRD2 beamline, and to comply with the top-up operations, a complete refurbishment of the Elettra Super Conducting Wiggler (SCW) has been carried out. Alongside with the mechanical, cryogenic and electrical components, also the electronics, the control and interlock systems have been upgraded. The MVME5110 PowerPC single board computer, which is a standard in the Elettra control system, has been adopted, as well as RS232 communication modules, analog to digital converters and digital I/O lines. In order to cope with the high output power of the SCW, up to18 KW, the interlock system, protecting both the wiggler and the beamline front-end, has been completely redesigned. The control system software has been re-written from scratch using the TANGO software framework. The complete system has been tested during the second half of 2014 and is now fully operational.

Phase 1 of TRIUMF Advanced Rare Isotope Laboratory (ARIEL) was completed in September 2014. At phase 1, the Low-Level RF (LLRF) system of ARIEL's electron linear accelerator (e-Linac) consists of a buncher and a deflector, one single-cavity injector cryomodule and the first cavity of two dual-cavity accelerating cryomodules. The model for the e-Linac LLRF system is largely based on the experience gained from the fully-commissioned TRIUMF ISAC-II linear accelerator (linac). Similarly, the EPICS-based Controls for the e-Linac LLRF builds on the lessons learned with the linac LLRF Controls. This paper describes the interface between the ARIEL Control System (ACS) and the e-Linac LLRF using EPICS ASYN/StreamDevice and a SCPI-like protocol. Also discussed are the ACS EDM displays and future plans for LLRF Controls.

To shorten the development time of supervision applications, CERN has developed the UNICOS framework, which simplifies the configuration of the front-end devices and the supervision (SCADA) layer. At CERN the SCADA system of choice is WinCC OA, but for specific projects (small size, not connected to accelerator operation or not located at CERN) a more customisable SCADA using LabVIEW is an attractive alternative. Therefore a similar system, called UNICOS in LabVIEW (UiL), has been implemented. It provides a set of highly customisable re-usable components, devices and utilities. Because LabVIEW uses different programming methods than WinCC OA, the tools for automatic instantiation of devices on both the front-end and supervision layer had to be re-developed, but the configuration files of the devices and the SCADA can be reused. This paper reports how the implementation was done, it describes the first project implemented in UiL and an outlook to other possible applications.

In J-PARC main ring, each of the main magnets (Dipole, Quadrupole, and Sextupole) has a trim-coil. The basic aim of trim-coil is to correct small deviation of each magnetic field. In addition, we have used them for other purposes, for example: (1) in Beam-Based-Alingnment studies, (2) as flux monitors, and (3) to make a short-circuit to reduce ripples of magnetic field. At a moment, trim-coils can be used for only one purpose. Relay-switches were introduced to change trim-coil connection to a device, which corresponds to the selected purpose. When the purpose is switched, 1,200 on-site relays have to be changed manually, distributed in three buildings. Thus, a control system for trim-coil relay-selectors was developed in winter, 2014-2015. EPICS tools and environment are used to develop the system. The system comprises PLC I/O modules with controller running EPICS on Linux. The system will be in operation after March, 2015. By using the system, a much easier switching of relay-switches than before, is expected.

The Rare Isotope Science Project at the Institute for Basic Science constructs the rare isotope accelerator (RAON) facility in South Korea. The stable ion beam as an ion source for the RAON accelerator could be generated by ECR ion source system. Therefore, it is mandatory to build ECR ion source control system that could be integrated into an accelerator control system easily. The vacuum control system is an essential part of the ECR control system, because of one vacuum chamber among three different voltage stages (ground, 50 kV, and 80 kV). The preliminary design and implementation of vacuum control system for the ECR ion source will be discussed. It is planned to use a PLC in order to communicate with a vacuum gauge and turbo pump controllers among multi-voltage stages (ground, 50 kV and 80 kV) by optical fibers connection. The PLC system has two major components: a digital I/O module that provides power to each component and standard RS-232 modules which are connected with the gauge & pump controllers. In addition, its extension plan to integrate the vacuum control system into the RAON accelerator control system based on system the EPICS framework, will be discussed.

359

ETH, Zurich, Switzerland

CAN bus is a recommended fieldbus at CERN. It is widely used in the control systems of the experiments to control and monitor large amounts of equipment (IO devices, front-end electronics, power supplies). CAN nodes are distributed over busses that are interfaced to the computers via PCI or USB CAN interfaces. These interfaces limit the possible evolution of the Detector Control Systems (DCS). For instance, PCI cards are not compatible with all computer hardware and new requirements for virtualization and redundancy require dynamic reallocation of CAN bus interfaces to different computers. Additionally, these interfaces cannot be installed at a different location than the front-end computers. Ethernet based CAN interfaces resolve these issues, providing network access to the field busses. The Ethernet-CAN gateways from Analytica (GmbH) were evaluated to determine if they meet the hardware and software specifications of CERN. This paper presents the evaluation methodology and results as well as highlighting the benefits of using such gateways in experiment production environments. Preliminary experience with the Analytica interfaces in the DCS of the CMS experiment is presented.

CERN, Geneva, Switzerland

For CERN's Linac4 (L4) Proton Synchrotron Booster (PSB) injection scheme, slices of the 160 MeV H⁻ beam will be distributed to the 4 superposed synchrotron rings of the PSB. The beam will then be injected horizontally into the PSB by means of an H⁻ charge-exchange injection system using a graphite stripping foil to strip the electrons from the H⁻ ions. The foil and its positioning mechanism will be housed under vacuum inside a stripping foil unit, containing a set of six foils that can be mechanically rotated into the beam aperture. The band with mounted foils is controlled by a stepping motor while a resolver, micro-switches and a membrane potentiometer provide foil position feedback. The vicinity of the ionizing beam and vacuum requirements have constrained the selection of the above mentioned control system parts. The positioning and interlocking logic is implemented in an industrial Programmable Logic Controller (PLC). This paper describes the design of the stripping foil unit electronics and controls and presents the first results obtained from a test bench unit which will be installed in the Linac4 transfer line by the end of the 2015 for foil tests with beam.

The RHIC Beam Permit System (BPS) monitors the anomalies occurring in the collider and restores the machine to a safe state upon fault detection. The reliability of the BPS thus directly impacts RHIC availability. An analytical multistate reliability model of the BPS has been developed to understand the failure development and propagation over store length variation. BPS has a modular structure. The individual modules have joint survival distributions defined by competing risks with exponential lifetimes. Modules differ in functionality and input response. The overall complex behavior of the system is analyzed by first principles for different failure/success states of the system. The model structure changes according to the type of scenario. The analytical model yields the marginal survival distribution for each scenario versus different store lengths. Analysis of structural importance and interdependencies of modules is also examined. A former Monte Carlo model* is used for the verification of the analytical model for a certain store length. This work is next step towards building knowledge base for eRHIC design by understanding finer failure characteristics of the BPS.

LAL, Orsay, France

ThomX is a Compton based photons source. It aims to produce a compact and directional X-rays source, with high performance, high brightness and adjustable energy*. The principal application fields are medical sciences, social technology and industry. An interlock system has been implemented for machine protection, especially to protect sensitive and essential equipment (magnets, vacuum system, etc.) during machine operation. ThomX interlock system is based on Programmable Logic Controller (PLC-Siemens S7-1500), it collects default signals from the different equipment of the machine, up to the central PLC which kills the beam, by stopping the RF or the injection, in case of problem (bad vacuum, magnets overheating, etc.). The interlock system consists of two levels. The first one is a local process, whose role is to monitor the variations of different parameters of the machine equipment, and generates a default signal in case of operation problem. The second level is the central PLC, which gathers and process all the default signals from subsystems, and stops the RF power in a very short time. Actually, the interlock system is under test, it will allow accelerator to work safely.

CERN, Geneva, Switzerland

Interlocks are an important feature of both personnel and machine protection systems for mitigating risks inherent in operation of dangerous equipment. The purpose of an interlock is to secure specific equipment or entire systems under well defined conditions in order to prevent accidents from happening. Depending on specific requirements for the level of reliability, availability, speed, and cost of the interlock, various technologies are available. Different approaches are discussed, in particular in the context of personnel safety systems, which have been built or tested at CERN during the last few years. Technologies discussed include examples of programmable devices, PLCs and FPGAs, as well as wired logic based on relays and special logic cards.

In this paper a new fast machine protection system is proposed. This system is designed for the injection Ι of C-ADS which fault reaction time requires less than 20us, and the one minute down time requires less than 7 times in a whole year. The system consist of one highly reliable control network based on a control board and some front IO sub-boards, and one nanosecond precision timing system using white rabbit protocol. The control board and front IO sub-board are redundant separately. The structure of the communication network is a combination structure of star and tree types which using the 2.5GHz optical fiber links the all nodes. This paper pioneered the use of nanosecond timing system based on the white rabbit protocol to determine the time and sequence of each system failure. Another advantage of the design is that it uses standard FMC and an easy extension structure which made the design is easy to use in a large accelerator.

Various upgrades were performed on the Large Hadron Collider (LHC) Beam Dumping System (LBDS) during Long Shutdown 1 (LS1) at CERN, in particular to the Trigger Synchronisation and Distribution System (TSDS): A redundant direct connection from the LHC Beam Interlock System to the re-trigger lines of the LBDS was implemented, a fully redundant powering architecture was set up, and new Trigger Synchronisation Unit cards were deployed over two separate crates instead of one. These hardware changes implied the adaptation of the State Control and Surveillance System and an improvement of the monitoring and diagnosis systems, like the various Internal Post Operation Check (IPOC) systems that ensure that, after every beam dump event, the LBDS worked as expected and is 'as good as new' for the next LHC beam. This paper summarises the changes performed on the TSDS during LS1, highlights the upgrade of the IPOC systems and presents the problems encountered during the commissioning of TSDS before the LHC Run II.

CERN, Geneva, Switzerland

ADaMS is CERN's Access Distribution and Management System. It evaluates access authorizations to more than 400 zones and for more than 35k persons. Although accesses are granted based on a combination of training courses followed, administrative authorizations and the radio-protection situation of an individual, the policies and technicalities are constantly evolving along with the laboratory's activities; the current version of ADaMS is based on a 7 year old design, and is starting to show its limits. A new version of ADaMS (3) will allow improved coordination with CERN's scheduling and planning tools (used heavily during technical shutdowns, for instance), will allow CERN's training catalog to change without impacting access management and will simplify and reduce the administrative workload of granting access. The new version will provide enhanced self-services to end users by focusing on access points (the physical barriers) instead of safety zones. ADaMS 3 will be able to cope better with changing and new requirements, as well as the multiplication of access points. The project requires the cooperation of a dozen services at CERN, and should take 18 months to develop.

The Equipment Protection Systems and Personnel Safety Systems of the ALBA Synchrotron are complex and highly distributed control systems based on PLC's from different vendors. EPS and PSS not only regulate the interlocks of the whole ALBA facility but provide an extense network of analog and digital sensors that collect information from all subsystems; as well as its logical states. TANGO is the Control System framework used at ALBA, providing several tools and services (GUI's, Archiving, Alarms) in which EPS and PSS systems must be integrated. PyPLC, a dynamic Tango device, have been developed in python to provide a flexible interface and enable PLC developers to automatically update it. This paper describes how protection systems and the PLC code generation cycle have been fully integrated within TANGO Control System at ALBA.

The beam abort system was installed in KEKB in order to protect the accelerator equipment and the Belle detector, and for radiation safety, from high current beams. For SuperKEKB, the new abort trigger system was developed. It collects more than 130 beam abort request signals and issues the beam abort trigger signal to the abort kickers. The request signals are partially aggregated in local control rooms located along the SuperKEKB ring and finally aggregated in central control room. In order to increase the system reliability, the VME-based module and the O/E module was developed, and all the abort signals between the modules are transmitted as optical signals. The VME-based module aggregates input signals and input signals are OR and latched. The E/O module converts electrical signal from abort request source to optical signal. The system also has the timestamp function to keep track of the abort signal received time. The timestamps are expected to contribute to identify the cause of the beam abort. Based on feasibility tests with a prototype module, the new module design was improved and fixed. This paper describes the details of the new abort trigger system.

CERN, Geneva, Switzerland

Engineering of Personnel Protection Systems (PPS) in large research facilities, such CERN, represents nowadays a major challenge in terms of requirements for safety and access control functionalities. PPS are usually conceived as two separate independent entities: a Safety System dealing with machine interlocks and subject to rigid safe-ty standards (e.g. IEC-61508); and a conventional Access Control System made by integration of different COTS technologies. The latter provides a large palette of func-tionalities and tools intended either to assist users access-ing the controlled areas, either to automate a certain number of control room operator's tasks. In this paper we analyse the benefits in terms of performance, cost and system maintainability of adopting the new generation of NI multipurpose CRIO 903x controllers. These new de-vices allows an optimal integration of a large set of access control functionalities, namely: automatic control of mo-torized devices, identification/count of users in zone, im-plementation of dedicated anti-intrusion algorithms, graphical display of relevant information for local users, and remote control/monitoring for control room opera-tors.

The Fermilab Accelerator Science and Technology (FAST) Facility will provide an electron beam with up to 3000 bunches per macro-pulse, 5Hz repetition rate and 300 MeV beam energy. The completed machine will be capable of sustaining an average electron beam power of close to 15KW at the bunch charge of 3.2nC. A robust Machine Protection System (MPS) capable of interrupting the beam within a macro-pulse and that interfaces well with new and existing controls system infrastructure has been developed to mitigate and analyze faults related to this relatively high damage potential. This paper describes the component layers of the MPS system, including a FPGA-based Permit Generator and Laser Pulse Controller, the Beam Loss Monitoring system design as well as the controls and related work done to date.

GSI, Darmstadt, Germany

Approaching the commissioning of CRYRING, the first accelerator to be operated using the new control system for FAIR (Facility for Antiproton and Ion Research), the new settings management system will also be deployed in a production environment for the first time. A major development effort is ongoing to realize requirements necessary to support accelerator operations at FAIR. The focus is on the pattern concept which allows controlling the whole facility with its different parallel beams in an integrative way. Being able to utilize central parts of the new control system already at CRYRING, before the first FAIR accelerators are commissioned, facilitates an early proof of concept and testing possibilities. Concurrently, refactorings and enhancements of the commonly used LSA (LHC Software Architecture) framework take place. At CERN, the interface to devices has been redesigned to enhance maintainability and diagnostics capabilities. At GSI, support for polynomials as a native datatype has been implemented, which will be used to represent accelerator settings as well as calibration curves. Besides functional improvements, quality assurance measures are being taken to increase code quality in prospect of productive use.

SOLEIL Computing division continuously needs to enhance its operational activities and minimize the workload of IT groups because IT performances directly impacts accelerators and beamlines operations in a context of an increase of the overall technical and organizational complexity. The Control & Data Acquisition group changed in 2013 it internal projects and support organization toward a service-oriented approach. This promising first step pointed out that enhancing the service delivered to our customers required to agree with them on a common vocabulary, on semantics and on operational processes. The ITIL* methodology appeared then as very good starting point to this purpose. This paper will describe the overall vision of our project 'Improving IT operation with a service oriented approach' and will detail the first ITIL operational processes we have adopted and how it helped us clarifying roles and responsibilities within our IT organization. In order to conclude the paper will give perspectives of using ITIL practices to enhance operational practices of other technical groups which activities strongly impact the service delivered to SOLEIL end users.

At FAIR the re-assembly of the well known CRYRING accelerator, formerly hosted by Manne Siegbahn Laboratory (MSL) Stockholm, is currently in progress. This compact low energy heavy ion synchrotron and experimental storage ring will be a testing platform for all control system (CS) concepts decided on for FAIR. The CRYRING CS will be based on the system originally developed by CERN which combines the JAVA based application level LSA (LHC Software Architecture) , the data acquisition level FESA (Front-End Software Architecture) and the White Rabbit based timing system. All parts have been enhanced with GSI specific functionality. In preparation for the commissioning of CRYRING later in 2015 all required beam instrumentation (BI) equipment including the software is now under development. The data acquisition (DAQ) concepts for the various instruments is presented, with emphasis on the seamless integration into the overall CS. For standard BI systems, such as digital imaging, profile and intensity measurement, VME and IndustryPC based DAQ systems are used. For beam position monitoring a new hardware strategy which combines the microTCA and FMC (FPGA mezzanine card) form factors is under evaluation.

Sirius is a new 3 GeV synchrotron light source currently being designed at the Brazilian Synchrotron Light Laboratory (LNLS) in Campinas, Brazil. The Control System will be distributed and digitally connected to all equipment in order to avoid analog signal cables. A three-layer control system will be used. The equipment layer uses RS485 serial networks, running at 10Mbps, with a light proprietary protocol, over a proprietary hardware, in order to achieve good performance. The middle layer, interconnecting these serial networks, is based on Beaglebone Black single board computer and commercial switches. Operation layer will be composed of PC's running EPICS client programs. Special topology will be used for Orbit Feedback with a dedicated commercial 10Gbps switch. The lower layers software implementation may use either (a) distributed EPICS conventional servers, the traditional approach, or (b) centralized EPICS server, using data servers and light proprietary protocol over Ethernet. Both cases use the same hardware and can run concurrently, sharing the control network. Measured performance with these two approaches will be presented.

In 2011, we started an ambitious project to refurbish key elements of the LANSCE accelerator that have become obsolete or were near end-of-life. The control system went through an upgrade process that affected different areas of LANSCE. Many improvements have been made but funding challenges and LANSCE operational commitments have delayed project deliverables. In this paper, we will discuss our upgrade choices, what we have accomplished so far, what we have learned about upgrading the existing control system and what challenges we still face.

Los Alamos National Laboratory has defined a new signature science facility, Matter-Radiation Interactions in Extremes (MaRIE) that builds on the existing capabilities of the Los Alamos Neutron Science Center (LANSCE). It will be the first multi-probe materials research center to combine high-energy, high-repetition-rate, coherent x-rays with electron and proton-beam charged-particle imaging to perform in-situ measurements of a sample in extreme environments. At its core, a 42-keV XFEL will be coupled with the LANSCE MW proton accelerator. A pre-conceptual design for MaRIE has been established. Technical risk reduction for the project includes an injector test-stand that is currently being designed. New accelerators are either planned, under construction, or currently in operation around the world, providing opportunities for the MaRIE project to leverage the instrumentation & controls (I&C) efforts of these facilities to minimize non-recurring engineering costs. This paper discusses possible MaRIE I&C system implementation choices and trade-offs, and also provides an overview of the proposed MaRIE facilities and the current design.

The Square Kilometer Array (SKA) project aims at building the world's largest radio observatory to observe the radio sky with unprecedented sensitivity and collecting area. In the SKA1 phase of the project, two dish arrays are to be built, one in South Africa (SKA1-Mid) and the other in Western Australia (SKA1-Survey). Each antenna will be provided with a local monitor and control system, enabling remote operations to engineers and to the Telescope Manager system. In this paper we present the current status of the software system being designed to monitor and control the dish subsystem. An overview of the dish instrumentation is reported, along with details concerning the software architecture, functional interfaces, prototyping and the evaluated technologies.

The Belle II e⁺/e⁻ collider experiment at KEK will include a new pixelated detector (PXD) based on DEPFET technology as the innermost layer. This detector requires a complex control and readout infrastructure consisting of several ASICs and FPGA boards. This paper present the architecture and EPICS-based implementation of the control, alarm, and interlock systems, their interface to the various subsystems, and to the NSM2-based Belle II run-control. The complex startup sequence is orchestrated by a statemachine. CSS is used to implement the user interface. The alarm system uses CSS/BEAST, and is designed to minimize spurious alarms. The interlock system consists of two main parts: a hardware-based system that triggers on adverse environmental (temperature, humidity, radiation) conditions, and a software-based system. Strict monitoring including the use of heartbeats ensures permanent protection and fast reaction times. Especially the power supply system is monitored for malfunctions, and all user inputs are verified before they are sent to the hardware. The control system also incorporates archiving, logging, and reporting in a uniform workflow for the ease of daily operation.

During the normal operation of the Large Hadron Collider, the high hadron flux level induced several Single Event Errors (SEE failure caused by a particle passing through) to the standard electronics installed. Such events perturbed LHC normal operation. As a consequence, a mitigation plan to minimise radiation-induced failures and optimise LHC operation was started: R2E mitigation project. This paper will deal with the mitigation problem for LHC/P8 equipment and the main improvements for the equipment in P4, with special focus on the controllers for the Active Magnetic Bearings used in the IHI-LINDE cold compressors. In addition, a new approach based on frequency response analysis to assess the cold compressor mechanical quality will be presented. The hardware and software design, implemented to increase the global reliability of the system, will be highlighted. A corresponding experiment protocol was developed at CERN in collaboration with the MECOS Company and the Universities of Sannio and Napoli Federico II. Preliminary experimental results showing the performance of the proposed approach on a case study for the cold compressor in P4 will be finally reported.

The Alba Controls Group develops and operates a diverse variety of controls software which is shared within international communities of users and developers. This includes: generic frameworks like Sardana* and Taurus**, numerous Tango*** device servers and applications where, among others, we can find PyAlarm and Panic****, and specific experiment procedures and hardware controllers. A study has commenced on how to improve the delivery process of our software from the hands of developers to laboratories, by making this process more reliable, predictable and risk-controlled. Automated unit and acceptance tests combined with the continuous integration, have been introduced, providing valuable and fast feedback to the developers. In order to renew and automate our legacy packaging and deployment system we have evaluated modern alternatives. The above practices were brought together into a design of the continuous delivery pipelines which were validated on a set of diverse software. This paper presents this study, its results and a proposal of the cost-effective implementation.

A Unified Approach to the Design of Orbit Feedback with Fast and Slow Correctors

494

DLS, Oxfordshire, United Kingdom

A unified control design is proposed to simultaneously determine control actions for both fast and slow arrays of correctors used for orbit feedback. By determining the interaction of the spatial subspaces of each array of correctors, spatial modes which require both fast and slow correctors can be identified. For these modes, a mid-ranging control technique is proposed to systematically allocate control action for each corrector. The mid-ranging control technique exploits the different dynamic characteristics of the correctors to ensure that the two arrays of actuators work together and avoid saturation of the fast correctors. Simulation results for the Diamond Storage Ring are presented.

DLS, Oxfordshire, United Kingdom

In 2016 Diamond Light Source will replace one double bend achromatic cell of the Storage Ring with two double bend achromatic cells in the same longitudinal space. This will create an additional straight section for an insertion device (ID), thereby converting a bending magnet source point into and ID source point. Installation of the two new cells and recommissioning of the SR will take place in an eight week shutdown. The additional components in the two new cells necessitate a substantial reworking of the interface layer of control system, together with changes to all applications dependent on the physics parameters of the storage ring. This paper will describe how it is planned to manage the control system aspects of the project.

DLS, Oxfordshire, United Kingdom

Closed loop stability of electron orbit feedback controllers is affected by mismatches between the accelerator model and the real machine. In this paper, the small gain theorem is used to express analytical criteria for closed loop stability in the presence of spatial uncertainty. It is also demonstrated how the structure of the uncertainty models affects the conservativeness of the robust stability results. The robust stability criteria are applied to the Diamond Light Source electron orbit controller and bounds on the allowable size of spatial uncertainties which guarantee closed loop stability is determined.

Uncertainty Modelling of Response Matrix

506

S. Gayadeen, M.T. Heron, G. Rehm
DLS, Oxfordshire, United Kingdom

Electron orbit feedback controllers are based on the inversion of the response matrix of the storage ring and as a result, mismatches between the accelerator model and the real machine can limit controller performance or cause the controller to become unstable. In order to perform stability analysis tests of the controller, accurate uncertainty descriptions are required. In this paper, BPM scaling errors, actuator scaling errors and drifts in tune are considered as the main sources of spatial uncertainties and because most electron orbit feedback systems use Singular Value Decomposition (SVD) to decouple the inputs and outputs of the system, the uncertainty can be expressed in terms of this decomposition. However SVD does not allow the main sources of uncertainty to be decoupled so instead, a Fourier-based decomposition of the response matrix is used to decouple and model the uncertainties. In this paper, both Fourier and SVD uncertainty modelling methods are applied to the Diamond Light Source storage ring and compared.

Remote monitoring and controls has always been an important aspect of physics detector controls since it was available. Due to the complexity of the systems, the 24/7 running requirements and limited human resources, remote access to perform interventions is essential. The amount of data to visualize, the required visualization types and cybersecurity standards demand a professional, complete solution. Using the example of the integration of the CMS detector controls system into our ORACLE WebCenter infrastructure, the mechanisms and tools available for integration with controls systems shall be discussed. Authentication has been delegated to WebCenter and authorization been shared between web server and control system. Session handling exists in either system and has to be matched. Concurrent access by multiple users has to be handled. The underlying JEE infrastructure is specialized in visualization and information sharing. On the other hand, the structure of a JEE system resembles a distributed controls system. Therefore an outlook shall be given on tasks which could be covered by the web servers rather than the controls system.

Funding: This manuscript has been authored by UT-Battelle, LLC under Contract No. DE-AC05-00OR22725 with the U.S. Department of Energy.
For several years, the Control System Studio (CS-Studio) Scan System has successfully automated the operation of beam lines at the Oak Ridge National Laboratory (ORNL) High Flux Isotope Reactor (HFIR) and Spallation Neutron Source (SNS). As it is applied to additional beam lines, we need to support simultaneous adjustments of temperatures or motor positions. While this can be implemented via virtual motors or similar logic inside the Experimental Physics and Industrial Control System (EPICS) Input/Output Controllers (IOCs), doing so requires a priori knowledge of experimenters requirements. By adding support for the parallel control of multiple process variables (PVs) to the Scan System, we can better support ad hoc automation of experiments that benefit from such simultaneous PV adjustments.

Gumtree is a software product developed at ANSTO and used for experimental control as well as data visualization and treatment. In order to simplify the interaction with instruments and optimize the available time for users, a user friendly multi sample workflow has been developed for Gumtree. Within this workflow users follow a step by step guide where they list available samples, setup instrument configurations and even specify sample environments. Users are then able to monitor the acquisition process in real-time and receive estimations about the completion time. In addition users can modify the previously entered information, even after the acquisitions have commenced. This paper will focus on how ANSTO integrated a multi sample workflow into Gumtree, what approaches were taken to allow realistic time estimations, what programming patterns were used to separate the user interface from the execution of the acquisition, and how standardization across multiple instruments was achieved. Furthermore, this paper will summarize the lessons learned during the development iterations, the feedback received from users and the future opportunities the approach enables.

Sardana* is a software suite for Supervision, Control and Data Acquisition in scientific installations. It aims to reduce cost and time of design, development and support of the control and data acquisition systems. Sardana is used in several synchrotrons where continuous scans are the desired way of executing experiments**. Most experiments require an extensive and coordinated control of many aspects like positioning, data acquisition, synchronization and storage. Many successful ad-hoc solutions have already been developed, however they lack generalization and are hard to maintain or reuse. Sardana, thanks to the Taurus*** based applications, allows the users to configure and control the scan experiments. The MacroServer, a flexible python based sequencer, provides parametrizable turn-key scan procedures. Thanks to the Device Pool controllers interfaces, heterogeneous hardware can be easily plug into Sardana and their elements used during scans and data acquisitions. Development of the continuous scans is an ongoing iterative process and its current status is described in this paper.

The European Spallation Source (ESS) in Lund, Sweden has just entered into neutron beam line construction starting detailed design in 2015. As a collaboration of 17 European countries the majority of hardware devices will be provided in-kind. This presents numerous technical and organizational challenges for the construction and the integration of the neutron instrumentation into the facility wide infrastructure; notably the EPICS control network and the facilities absolute timing system. In this contribution we present a strategy for the modularity of the instruments hardware with well-defined standardized functionality and a minimized number of control & data interfaces. Key point of the strategy is the time stamping of all readings from the instruments control electronics extending the event mode data acquisition from detected neutron events to all metadata. This gives the control software the flexibility necessary to adapt the functionality of the instruments to the demands of each single experimental run. Examples of the advantages of that approach in classical motion control as well as in complex robotics systems and matching hardware requirements necessary, is discussed.

The French Atomic and Alternative Energies Commission (CEA : Commissariat à l'Energie Atomique et aux Energies Alternatives) is currently building the Laser MegaJoule facility. In 2014, the first 8 beams and the target area were commissioned and the first physics campaign (a set of several shots) was achieved. On the LMJ, each shot requires more or less the same operations except for the settings that change from shot to shot. The supervisory controls provide five semi-automated sequence programs to repeat and schedule actions on devices. Three of them are now regularly used to drive the LMJ. Sequence programs need to have different qualities such as flexibility, contextual adaptability, reliability and repeatability. Currently, the calibration shots sequence drives 328 actions towards local control systems. However, this sequence is already dimensioned to drive 22 bundles, which will lead to manage almost 5300 actions. This paper introduces the organization of the control system used by sequence programs, the sequence adjustments files, the grafcets of sequences, the GUIs, the software and different tools used to control the facility.

Machine Protection and Interlock System for Large Research Instruments

R. Schmidt
CERN, Geneva, Switzerland

Major research instruments such as accelerators and fusion reactors operate with large amount of power and energy stored in beams and superconducting magnets. Highly reliable Machine Protection systems are required to operate such instruments without damaging equipment in case of failure. The increased interest in protection is related to the increasing beam power of high-power proton accelerators such as ISIS, SNS, ESS and the PSI cyclotron, to the large energy stored in the beam (in particular for hadron colliders such as LHC) and to the stored energy in magnet systems such as for ITER and LHC. Machine Protection includes process and equipment monitoring, a system to safely stop operation (e.g. dumping the beam or extracting the energy stored in the magnets) and an interlock system for highly reliable communication between protection systems. Depending on the application, the reaction of the protection function to failures must be very fast (for beam protection systems down to some us). In this paper an overview of the challenges for protection is given, and examples of interlock systems and their use during operation are presented.

Safety Integrity Level (SIL) Verification for SLAC Radiation Safety Systems

F. Tao, E. Carrone, J.M. Murphy, K.T. Turner
SLAC, Menlo Park, California, USA

SIL is a key concept in functional safety standards: it is a performance measure on how reliable is a safety system performing a particular safety function. In the system design stage, SIL verification must be performed to prove that the SIL achieved meets/exceeds the SIL assigned during risk assessment, to comply with standards. Unlike industrial applications, where safety systems are usually composed of certified devices or devices with long usage history, safety systems in large physics laboratories are less standardized and more complex in terms of system architecture and devices used. In addition, custom designed electronics are often employed, with limited reliability information. Verifying SIL for these systems requires in-depth knowledge of reliability evaluation. In this paper, it is demonstrated how to determine SIL using SLAC radiation safety systems (Personnel Protection System (PPS) and Beam Containment System (BCS)) as examples. PPS utilizes commercial safety rated devices, while BCS also contains customized electronics. Choice of standards, methods of evaluation, reliability data gathering process (both from industry and from hardware development) are also discussed.

The French Laser Megajoule (LMJ) is, behind the US NIF, the second largest inertial fusion facility in the World. The main activity of this facility is the acquisition of several physical phenomena as neutron, gamma, X rays…produced by the indirect attack of hundreds of high power laser beams on targets through measurement devices called "target diagnostics". More than 30 diagnostics will be installed and driven in a huge and complex integrated computer control system. The aim of this paper is to describe an architecture based on the Tango open source software for the very low level control system, Python language for the development of drivers and the French commercial PANORAMA software as the main high level SCADA. This choice leads to guaranty the evolution of the middleware software architecture of this facility supposed to be operated during dozen of years with the capability of using many instruments including sustainability.

The ELI-Beamlines facility aims to provide a selection of high-energy and high repetition-rate TW-PW femtosecond lasers driving high intensity XUV/X-ray and accelerated particle secondary sources for applications in materials, medical, nuclear and high-field physics sectors. The highest repetition rate laser in the facility will be the L1 laser, producing 1 kHz, 20 fs laser pulses of 200 mJ energy. This laser is based entirely on picosecond chirped-pulse parametric amplification and solid-state pump lasers. The high repetition rate combined with kW pump powers and advanced technologies calls for a highly automated, reliable and flexible control system. Current progress on the L1 control system is discussed, focussing on the architecture, software and hardware choices. Special attention is given to the LabVIEW-EPICS framework that was developed for the ELI Beamlines lasers. This framework offers comprehensive and scalable EPICS integration while allowing the full range of LabVIEW real-time and FPGA embedded targets to be leveraged in order to provide adaptable, high-performance control and rapid development.

The ambitious commissioning plans for the European XFEL require that many of the high-level controls are ready from the beginning. The idea arose to create a virtual environment to carry out such developments and tests in advance, to test interfaces, software in general and the visualisation of the variety of components. Based on the experiences and on the systems that are already in operation at the FLASH facility for several years, such a virtual environment is being created. The system can already simulate most of the key components of the upcoming accelerator. Core of the system is an event synchronized data acquisition system (DAQ). The interfaces of the DAQ system towards the device level, as well as to the high-level side is utilising the same software stack as the production system does. Thus, the software can be developed and used interchangeably between the virtual and the real machine. This allows to test concepts, interfaces and identify problems and errors at an early stage. In this paper the opportunities arising from the operation of such a virtual machine will be presented. The limits in terms of the resulting complexity and physical relationships will also be shown.

Together with its partners from the Helmholtz Association and from industry, DESY is developing a control system adapter. It allows to write applications in a control system independent way, while still being able to update the process variables and react on control system triggers. We report on the status of the project and the experience we gained trying to write portable device servers.

This paper presents the latest news from the TANGO collaboration. TANGO is being used in new domains. The three ELI pillars - ELI-Beamlines, ELI-ALPS and ELI-NP in Czech Republic, Hungary and Romania respectively have selected TANGO for many of their control systems. In ELI-Beamlines and ELI-Alps, TANGO will play the role of integrating all the hardware and turn-key systems (some delivered with EPICS or Labview) into one integrated system. In ELI-NP, the HPLS and LBTS will be controlled using TANGO, while the GBS will be controlled using EPICS. On the experimental side, ELI-NP will use both TANGO and EPICS control systems. TANGO will be extended with new features required by the laser community. These features will include nanosecond time-stamping. The latest major release of TANGO V9 includes the following features - data pipes, enumerated types, dynamic commands and forwarded attributes. The collaboration has been extended to include the new members and to provide a sustainable source of resources through collaboration contracts. A new website (http://www.tango-controls.org/) has been designed which improves the communication within the community.

EPICS version 4 is a set of software modules that add to the base of the EPICS toolkit for advanced control systems. Version 4 adds the possibility of process variable values of structured data, an introspection interface for dynamic typing plus some standard types, high-performance streaming, and a new front-end processing database for managing complex data I/O. A synchronous RPC-style facility has also been added so that the EPICS environment supports service-oriented architecture. We introduce EPICS and the new features of version 4. Then we describe selected deployments, particularly for high-throughput experiment data transport, experiment data management, beam dynamics and infrastructure data.

Towards Building Reusability in Control Systems - a Journey

Tata Research Development and Design Centre, Pune, India

Development of similar systems leads to a strong motivation for reuse. Our involvement with three large experimental physics facilities led us to appreciate this better in the context of development of their respective monitoring and control (M&C) software. We realized that the approach to allowing reuse follows the onion skin model that is, building re-usability in each layer in the solution to the problem. The same motivation led us to create a generic M&C architecture through our first collaborative effort which resulted into a fairly formal M&C domain model. The second collaboration showed us the need to have a common vocabulary that could be used across multiple systems to specify respective domain specific M&C solutions at higher levels of abstraction implemented using the generic underlying M&C engine. This resulted in our definition and creation of a domain specific language for M&C. The third collaboration leads us to imagine capturing domain knowledge using the common vocabulary which will substantially further reuse, this thought is already demonstrated through a preliminary prototype. We discuss our learning through this journey in this paper.

This paper describes a new approach for generic design and efficient development of OPC Unified Architecture (UA) servers. Development starts with creation of a design XML file, describing an OO information model of the target system or device. Using this model, the framework generates an executable OPC UA server exposing the per-design address space without writing a single line of code while supporting standalone or embedded platforms. Further, the framework generates skeleton code for the interface logic of the target system or device. This approach allows both novice and expert developers to create servers for the systems they are experts in while greatly reducing design and development effort as compared to developments based on COTS OPC UA toolkits. Higher level software such as SCADA systems may benefit from using the design description to generate client connectivity configuration and data representation as well as validation tools. In this contribution, the concept and implementation of this framework is detailed along with examples of actual production-level usage in the detector control system of the ATLAS Experiment at CERN and beyond.

Disruptor - Using High Performance, Low Latency Technology in the CERN Control System

software, framework, hardware, data-acquisition

606

M. Gabriel, R. Gorbonosov
CERN, Geneva, Switzerland

Accelerator control systems process thousands of concurrent events per second, which adds complexity to their implementation. The Disruptor library provides an innovative single-threaded approach, which combines high performance event processing with a simplified software design, implementation and maintenance. This open-source library was originally developed by a financial company to build a low latency trading exchange. In 2014 the high-level control system for CERN experimental areas (CESAR) was renovated. CESAR calculates the states of thousands of devices by processing more than 2500 asynchronous event streams. The Disruptor was used as an event-processing engine. This allowed the code to be greatly simplified by removing the concurrency concerns. This paper discusses the benefits of the programming model encouraged by the Disruptor (simplification of the code base, performance, determinism), the design challenges faced while integrating the Disruptor into CESAR as well as the limitations it implies on the architecture.

ZeroMQ is an emerging message oriented middleware architecture that is being increasingly adopted in the software engineering of distributed control and data acquisition systems within the accelerator community. The rich array of built-in core messaging patterns may, however, be equally applied to within the domain of high-level applications, where the seamless integration of accelerator models and message logging capabilities, respectively serve to extend the effectiveness of beam dynamics applications and allow for their monitoring. Various advanced patterns that include intermediaries and proxies further provide for reliable service-oriented brokers, as may be required in real-world operations. A report on an investigation into ZeroMQ's suitability for integrating key distributed components into high-level applications, and the experience gained, are presented.

KU Leuven, Leuven, Belgium

Knowledge representation and reasoning are hot topics in academics and industry today, as they are enabling technologies for building more complex and intelligent future systems. At the Mercator Telescope, we've built a software framework based on these technologies to support the design of our control systems. At the heart of the framework is a metamodel: a set of ontologies based on the formal semantics of the Web Ontology Language (OWL), to provide meaningful reusable building blocks. Those building blocks are instantiated in the models of our control systems, via a Domain Specific Language (DSL). The metamodels and models jointly form a knowledge base, i.e. an integrated model that can be viewed from different perspectives, or processed by an inference engine for model verification purposes. In this paper we present a tool called OntoManager, which demonstrates the added value of semantic modeling to the engineering process. By querying the integrated model, our web-based tool is able to generate systems engineering views, verification test reports, graphical software models, PLCopen compliant software code, Python client-side code, and much more, in a user-friendly way.

This paper describes the phase-locked loop algorithms that are used by the real-time power converter controllers at CERN. The algorithms allow the recovery of the machine time and events received by an embedded controller through WorldFIP or Ethernet-based fieldbuses. During normal operation, the algorithm provides less than 10 μs of time precision and 0.5 μs of clock jitter for the WorldFIP case, and less than 2.5 μs of time precision and 40 ns of clock jitter for the Ethernet case.

The High Repetition-Rate Advanced Petawatt Laser System (HAPLS) forms part of the European Union's Extreme Light Infrastructure Beamlines project (ELI-Beamlines) which will be the first international laser research infrastructure of its kind. HAPLS will generate peak powers greater than one petawatt at a repetition rate of 10 Hz with 30fs wide pulses. ELI will enable unprecedented techniques for many diverse areas of research. HAPLS requires a high-precision timing system that operates either independently or synchronized with ELI's system. Greenfield Technology, a producer of mature picosecond timing systems for several years, has been hired by LLNL* to provide just such a timing system. It consists of a central Master Timing Generator (MTG) that generates and transmits serial data streams over an optical network that synchronizes local multi-channel delay generators which generate trigger pulses to a resolution of 1ps. The MTG is phase-locked to an external 80 MHz reference that ensures a jitter of less than 10ps. The various qualities and functions of this timing system are presented including the LabVIEW interface and precision phase locking to the 80MHz reference.
*LLNL is operated by Lawrence Livermore National Security, LLC, for the U.S. Department of Energy, National Nuclear Security Administration under Contract DE-AC52-07NA27344.

JASRI/SPring-8, Hyogo-ken, Japan

The data logging system for SPring-8 was upgraded to the new system using NoSQL database, as a part of a MADOCA II framework. It has been collecting all the log data required for accelerator control without any trouble since the upgrade. In the past, the system powered by a relational database management system (RDBMS) had been operating since 1997. It had grown with the development of accelerators. However, the system with RDBMS became difficult to handle new requirements like variable length data storage, data mining from large volume data and fast data acquisition. New software technologies gave solution for the problems. In the new system, we adopted two NoSQL databases, Apache Cassandra and Redis, for data storage. Apache Cassandra is utilized for perpetual archive. It is a scalable and highly available column oriented database suitable for time series data. Redis is used for the real time data cache because of a very fast in-memory key-value store. Data acquisition part of the new system was also built based on ZeroMQ message packed by MessagePack. The operation of the new system started in January 2015 after the long term evaluation over one year.

D.S. Willingham
ASCo, Clayton, Victoria, Australia

Overview using Data Analytics to turn large volumes of complex data into actionable information can help you improve design and decision-making processes. In today's world, there is an abundance of data being generated from many different sources. However, developing effective analytics and integrating them into existing systems can be challenging. Big data represents an opportunity for analysts and data scientists to gain greater insight and to make more informed decisions, but it also presents a number of challenges. Big data sets may not fit into available memory, may take too long to process, or may stream too quickly to store. Standard algorithms are usually not designed to process big data sets in reasonable amounts of time or memory. There is no single approach to big data. Therefore, MATLAB provides a number of tools to tackle these challenges. In this paper 2 case studies will be presented: 1. Manipulating and doing computations on big datasets on light weight machines; 2. Visualising big, multi-dimensional datasets Developing Predictive Models High performance computing with clusters and Cloud Integration with Databases, HADOOP and Big Data Environments.

The CLS uses the EPICS Distributed Control System (DCS) for control and feedback of a linear accelerator, booster ring, electron storage ring, and numerous x-ray beamlines. The number of host computers running EPICS IOC applications has grown to 200, and the number of IOC applications exceeds 700. The first part of this paper will present the challenges and current efforts to monitor and report the status of the control system itself by monitoring the EPICS network traffic. This approach does not require any configuration or application modification to report the currently active applications, and then provide notification of any changes. The second part will cover the plans to use the information collected dynamically to improve upon the information gathered by process variable crawlers for an IRMIS database, with the goal to eventually replace the process variable crawlers.

MADOCA II is a next generation of the Message And Database Oriented Control Architecture (MADOCA) and a message driven distributed control framework as in MADOCA, but several functions such as control on Windows and messaging with variable-length data were implemented by using ZeroMQ. A prototype of LabVIEW interface was also developed with a VI library of ZeroMQ and implemented into our control system at SPring-8 since 2013, as presented at last ICALEPCS meeting. However, it is recognized that the interface should be very easy to use to be spread for wide LabVIEW usage. In this paper, a new redesigned LabVIEW interface is presented. In the new interface, messages and variable-length data such as image data can be managed with key-value stores. Applications for client program and equipment management server can be easily constructed. The VIs are based on a dynamic link library (DLL) developed using C++ language. Therefore, the upgrade on the interface is easily carried out with the replacement of DLL. The DLL can be also used from other languages such as Python and C++. The adoption of a new LabVIEW interface into our facility such as control of experimental stations is planned.

The Computer-on-Module approach makes cutting edge technology easily accessible and lowers the entry barriers to anyone prototyping and developing embedded systems. Furthermore, it is possible to add all the system specific functionalities to the generic PC functions which are readily available in an off-the-shelf core module reducing the time to market and enhancing the creativity of system engineers. The purpose of this paper is to show a custom hardware platform based on the tiny and low power Intel Edison Compute Module, which uses a 22nm Intel processing core and contains connectivity elements to ensure device-to-device and device-to-cloud connectivity. The Intel Edison carrier board designed is expected to act as a local intelligent node, a readily available custom EPICS*,** IOC for extending the control reach to small appliances in the context of the SPES project. The board acts as an Ethernet to RS232/RS422 interface translator with Power-Over-Ethernet supply and network booting as key features of this platform. The x86 architecture of the Edison makes standard Linux software deployment straightforward. Currently the board is in prototyping stage.

R. Bacher
DESY, Hamburg, Germany

The advent of advanced mobile, gaming and augmented reality devices provides users with novel interaction modalities. Today's accelerator control applications do not provide features like speech, finger and hand gesture recognition or even gaze detection. Their look-and-feel and handling are typically optimized for mouse-based interactions and are not well suited for the specific requirements of more complex interaction modalities. This paper describes the conceptual design and implementation of an intuitive single-user, multi-modal human-machine interface for accelerator operation and maintenance applications. The interface seamlessly combines standard actions (mouse), actions associated with 2D single/multi-finger gestures (touch sensitive display) and 3D single/multi-finger and hand gestures (motion controller), and spoken commands (speech recognition system). It will be an integral part of the web-based, platform-neutral Web2cToGo framework belonging to the Web2cToolkit suite and will be applicable for desktop and notebook computers, tablet computers and smartphones, and even see-through augmented reality glasses.

This paper presents a graphical interface for displaying status information and enabling user interaction with the Tango based control system for the MAX IV synchrotron. It focuses on bringing an intuitive view of the whole system, so that operators can quickly access the controls for any hardware based on its physical location. The view is structured into different layers that can be selectively shown, and various live updated information can be displayed in the form of e.g. colour or text. Panning and zooming is supported, as well as invoking commands. The interface is defined by an SVG drawing which can be edited without programming expertise. Since our system is based on modern web technologies, it can be run as a web service accessible by standard browsers, but it can also be integrated in GUI applications.

ESRF, Grenoble, France

The TANGO release 8 led to several enhancements, including the adoption of the ZeroMQ library for faster and lightweight event-driven communication. Exploiting these improved capabilities, a high performance, event-driven archiving system, named Tango HDB++*, has been developed. Its design gives the possibility to store archiving data into Apache Cassandra: a high performance scalable NoSQL distributed database, providing High Availability service and replication, with no single point of failure. HDB++ with Cassandra will open up new perspectives for TANGO in the era of big data and will be the starting point of new big data analytics/data mining applications, breaking the limits of the archiving systems which are based on traditional relational databases. This paper describes the current state of the implementation and our experience with Apache Cassandra in the scope of the Tango HDB++ project. It also gives some performance figures and use cases where using Cassandra with Tango HDB++ is a good fit.
* HDB++ project is the result of a collaboration between the Elettra synchrotron (Trieste) and the European Radiation Synchrotron Facility (Grenoble)

ESPRESSO, the Echelle SPectrograph for Rocky Exoplanet and Stable Spectroscopic Observations, is a super-stable Optical High Resolution Spectrograph for the Combined Coudé focus of the VLT. It can be operated either as a single telescope instrument or as a multi-telescope facility, by collecting the light of up to four UTs. From the Nasmyth focus of each UT the light is fed, through a set of optical elements (Coudé Train), to the Front End Unit which performs several functions, as image and pupil stabilization, inclusion of calibration light and refocusing. The light is then conveyed into the spectrograph fibers. The whole process is handled by several electronically controlled devices. About 40 motorized stages, more than 90 sensors and several calibration lamps are controlled by the Instrument Control Electronics (ICE) and Software (ICS). The technology employed for the control of the ESPRESSO subsystems is PLC-based, with a distributed layout close to the functions to control. This paper illustrates the current status of the ESPRESSO ICE, showing the control architecture, the electrical cabinets organization and the experiences gained during the development and assembly phase.

M. Di Cosmo, B. Todd
CERN, Geneva, Switzerland

The CERN Accelerator Complex consists of several generations of particle accelerators, having around 5000 power converters supplying regulated current and voltage to normal and superconducting magnets. Today around 12 generations of legacy control system types are in operation in the accelerator complex, having significant impact on operability, support and flexibility for the converter controls electronics. Over the past years a new generation of modular controls called RegFGC3 has been developed by CERN's power conversion group. The goal is to provide a new standardised and cost effective control solution, supporting the largest number of converter topologies in a single platform. This will reduce the maintenance cost by decreasing the variety and diversity of control systems whilst simultaneously improving the operability of power converters. This paper describes Thyristor-based power converter controls as well as the on-going design and realization, focusing on functional requirements and first implementation.

JAMK, Jyväskylä, Finland

Many commercial systems used for controls nowadays contain embedded web servers. Secure access to these, often essential, facilities is of utmost importance, yet it remains complicated to manage for different reasons (e.g. obtaining and applying patches from vendors, ad-hoc oversimplified implementations of web-servers are prone to remote exploit). In this paper we describe a security-mediating proxy system, which is based on the well-known Apache httpd software. We describe how the use of the proxy made it possible to simplify the infrastructure necessary to start WinCC OA-based supervision applications on operator consoles, providing, at the same time, an improved level of security and traceability. Proper integration with the CERN central user account repository allows the operators to use their personal credentials to access applications, and also allows one to use standard user management tools. In addition, easy-to-memorize URL addresses for access to the applications are provided, and the use of a secure https transport protocol is possible for services that do not support it on their own.

This paper reports the progress of the control system for accelerator injector II used in China initiative accelerator driven sub-critical (ADS) facility. As a linear proton accelerator, injector II includes an ECR ion source, a low-energy beam transport line, a radio frequency quadrupole accelerator, a medium energy beam transport line, several crymodules, and a diagnostics plate. Several subsystems in the control system have been discussed, such as a machine protection system, a timing system, and a data storage system. A three-layer control system has been developed for injector II. In the equipment layer, the low-level control with various industrial control cards, such as programmable logic controller and peripheral component interconnect (PCI), have been reported. In the middle layer, a redundant Gigabit Ethernet based on the Ethernet ring protection protocol has been used in the control network for Injector II. In the operation layer, high-level application software has been developed for the beam commissioning and the operation of the accelerator. Finally, by using this control system, the proton beam commissioning for Injector II in the control room has been mentioned.

Access and safety systems are traditionally considered critical in organizations and they are therefore usually well isolated from the rest of the network. However, recent years have seen a number of cases, where such systems have been compromised even when in principle well protected. The tendency has also been to increase information exchange between these systems and the rest of the world to facilitate operation and maintenance, which further serves to make these systems vulnerable. In order to gain insight on the overall level of information security of CERN access and safety systems, a security assessment was carried out. This process consisted not only of a logical evaluation of the architecture and implementation, but also of active probing for various types of vulnerabilities on test bench installations.

The Detector Control System (DCS) of the Compact Muon Solenoid (CMS) experiment ran with high availability throughout the first physics data-taking period of the Large Hadron Collider (LHC). This was achieved through the consistent improvement of the control software and the provision of a 24-hour expert on-call service. One remaining potential cause of significant downtime was the failure of the computers hosting the DCS software. To minimize the impact of these failures after the restart of the LHC in 2015, it was decided to implement a redundant software layer for the control system where two computers host each DCS application. By customizing and extending the redundancy concept offered by WinCC Open Architecture (WinCC OA), the CMS DCS can now run in a fully redundant software configuration. The implementation involves one host being active, handling all monitoring and control tasks, with the second host running in a minimally functional, passive configuration. Data from the active host is constantly copied to the passive host to enable a rapid switchover as needed. This paper describes details of the implementation and practical experience of redundancy in the CMS DCS.

At the X-ray Free Electron Laser (XFEL) facility, SACLA, an event-synchronized data acquisition system has been utilized for the XFEL operation. This system collects every shot-by-shot data, such as point data of the phase and amplitude of the RF cavity pickup signals, in synchronization with the beam operation cycle. This system also acquires RF waveform data every 10 minutes. In addition to the periodic waveform acquisition, an abnormal RF waveform that suddenly occurs should be collected for failure diagnostics. Therefore, we developed an abnormal RF waveform data acquisition (DAQ) system, which consists of the VME systems, a cache server, and a NoSQL database system, Apache Cassandra. When the VME system detects an abnormal RF waveform, it collects all related waveforms of the same shot. The waveforms are stored in Cassandra through the cache server. Before the installation to SACLA, we ensured the performance with a prototype system. In 2014, we installed the DAQ system into the injection part with five VME systems. In 2015, we will acquire waveforms from the low-level RF control system configured by 74 VME systems at the SACLA accelerator.

The MicroTCA.4 crate standard provides a powerful electronic platform for digital and analogue signal processing. Besides excellent hardware modularity, it is the software reliability and flexibility as well as the easy integration into existing software infrastructures that will drive the widespread adoption of the new standard. The DESY MicroTCA.4 User Tool Kit (MTCA4U) comprises three main components: A Linux device driver, a C++ API for accessing the MicroTCA.4 devices and a control system interface layer. The main focus of the tool kit is flexibility to enable fast development. The universal, expandable PCI Express driver and a register mapping library allow out of the box operation of all MicroTCA.4 devices which are running firmware developed with the DESY board support package. The tool kit has recently been extended with features like command line tools and language bindings to Python and Matlab.

ALICE (A Large Ion Collider Experiment) is one of the big LHC (Large Hadron Collider) detectors at CERN. It is composed of 19 sub-detectors constructed by different institutes participating in the project. Each of these subsystems has a dedicated control system based on the commercial SCADA package "WinCC Open Architecture" and numerous other software and hardware components delivered by external vendors. The task of the central controls coordination team is to supervise integration, to provide shared services (e.g. database, gas monitoring, safety systems) and to manage the complex infrastructure (including over 1200 network devices and 270 VME and power supply crates) that is used by over 100 developers around the world. Due to the scale of the control system, it is essential to ensure that reliable and accurate information about all the components - required to deliver these services along with relationship between the assets - is properly stored and controlled. In this paper we will present the techniques and tools that were implemented to achieve this goal, together with experience gained from their use and plans for their improvement.

The control system had been established for the new 3 GeV synchrotron light source (Taiwan Photon Source, TPS) which was successful to commission at December 2014. Various control system platforms with the EPICS framework had been implemented and commissioned. The relational database (RDB) has been set up for some of the TPS control system applications used. The EPICS data archive systems are necessary to be built to record various machine parameters and status information into the RDB for long time logging. The specific applications have been developed to analyze the archived data which retrieved from the RDB. One EPICS alarm system is necessary to be set up to monitor sub-system status and record detail information into the RDB if the problem happened. Some Web-based applications with RDB have been gradually created to show the TPS machine status related information. The efforts are described at this paper.

In this paper, we report the conceptual design of control networks used in the control system for China initiative accelerator driven sub-critical (ADS) facility which consists of two accelerator injectors, a main accelerator, a spallation target and a reactor. Because different applications have varied expectations on reliability, latency, jitter and bandwidth, the following networks have been designed for the control systems, i.e. a central operation network for the operation of accelerators, target, and reactor; a reactor protection network for preventing the release of radioactivity to the environment; a personnel protection network for protecting personnel against unnecessary exposure to hazards; a machine protection network for protecting the machines in the ADS system; a time communication network for providing timing and synchronization for three accelerators; and a data archiving network for recording important measurement results from accelerators, target and reactor. Finally, we discuss the application of high-performance Ethernet technologies, such as Ethernet ring protection protocol, in these control networks for CIADS.

The Intelligent Platform Management Interface (IPMI) is a standardized interface to management functionalities of computer systems. The data provided typically includes the readings of monitoring sensors, such as fan speeds, temperatures, power consumption, etc. It is provided not only by servers, but also by uTCA crates that are often used to host an experiment's control and readout system. Therefore, it is well suited to monitor the health of the hardware deployed in HEP experiments. In addition, the crates can be controlled via IPMI with functions such as triggering a reset, or configuring IP parameters. We present the design and functionality of an EPICS module to interface to IPMI that is based on ipmitool. It supports automatic scanning for IPMI sensors and filling the PV metadata (units, meaning of status words in mbbi records) from the IPMI sensor information. Most importantly, the IPMI-provided alarm thresholds are automatically placed in the PV for easy implementation of an alarm system to monitor IPMI hardware.

Control systems for Radio Astronomy projects such as MeerKAT* require testing functionality of different parts of the Telescope even when the system is not fully developed. Usage of software simulators in such scenarios is customary. Projects build simulators for subsystems such as Dishes, Beamformers and so on to ensure the correctness of a) their interface to the control system b) logic written to coordinate and configure them. However, such simulators are developed as one-offs, even when they implement similar functionality. This leads to duplicated effort impacting large projects such as Square Kilometer Array**. We leverage the idea of data driven software development and conceptualize a simulation framework that reduces the simulator development effort, to mitigate this: 1) capturing all the necessary information through instantiation of a well-defined simulation specification model, 2) configuring a reusable engine that performs the required simulation functions based on the instantiated and populated model provided to it as input. The results of a PoC for such a simulation framework implemented in the context of Giant Meter-wave Radio Telescope*** are presented.

DESY, Hamburg, Germany

The Simple Network Management Protocol (SNMP) is an open-source protocol that allows many manufacturers to utilize it for controlling and monitoring their hardware. More and more SNMP-manageable devices show up on the market that can be used by control systems for accelerators. Some SNMP devices are being used at the free-electron laser (FLASH) at DESY and planned to be used at the European X-ray Free Electron Laser (XFEL) in Hamburg, Germany. To provide an easy and uniform way of controlling SNMP devices a server has been developed. The server configuration, with respect to device parameters to control, is done during its start-up and driven by the manufacturer Management Information Base (MIB) files provided with SNMP devices. This paper gives some details of the server design, its implementation and examples of use.

The Low level RF system for the European XFEL is controlling the accelerating RF fields in order to meet the specifications of the electron bunch parameters. A hardware platform based on the MicroTCA.4 standard has been chosen, to realize a reliable, remotely maintainable and high performing integrated system. Fast data transfer and processing is done by field programmable gate arrays (FPGA) within the crate, controlled by a CPU via PCIe communication. In addition to the MTCA system, the LLRF comprises external supporting modules also requiring control and monitoring software. In this paper the LLRF system high level software used in E-XFEL is presented. It is implemented as a semi-distributed architecture of front end server instances in combination with direct FPGA communication using fast optical links. Miscellaneous server tasks have to be executed, e.g. fast data acquisition and distribution, adaptation algorithms and updating controller parameters. Furthermore the inter-server data communication and integration within the control system environment as well as the interface to other subsystems are described.

The EPICS Archiver Appliance was developed by a collaboration of SLAC, BNL and FRIB to allow for the archival of millions of PVs, mainly focusing on data retrieval performance. It offers the ability to cluster appliances and to scale by adding appliances to the cluster. Multiple stages and an inbuilt process to move data between stages facilitates the usage of faster storage and the ability to decimate data as it is moved. An HTML management interface and scriptable business logic significantly simplifies administration. Well-defined customization hooks allow facilities to tailor the product to suit their requirements. Mechanisms to facilitate installation and migration have been developed. The system has been in production at SLAC for about 2 years now, at FRIB for about a year and is heading towards a production deployment at BNL. At SLAC, the system has significantly reduced maintenance costs while enabling new functionality that was not possible before. This paper presents an overview of the system and shares some of our experience with deploying and managing it at our facilities.

RIKEN Nishina Center, Wako, Japan

For the RIBF project (RIKEN RI Beam Factory), the EPICS-based distributed control system is utilized on Linux and vxWorks as an embedded EPICS technology. Utilizing NAS that have a High-Availability system as a shared storage, common EPICS programs (Base, Db, and so on) are shared with each EPICS IOC. In March 2015, the control system continues to grow and consists of about 50 EPICS IOCs, and more than 100, 000 EPICS records. For a large number of control hardware devices, the dependencies between EPICS records and EPICS IOCs are complicated. For example, it is not easy to know accurate device information by only the EPICS record name information. Therefore, new management system was constructed for RIBF control system to call up detailed information easily. In the system, by parsing startup script files (st.cmd) for running EPICS IOCs, all EPICS records and EPICS fields are stored into the PostgreSQL-based database. By utilizing this stored data, it is successful to develop Web-based management and search tools. In this paper the system concept, the feature of the Web-based tools for the management, is reported in detail.

We use standard distributed control system (DCS) architecture. The software is the standard three-layer structure. OPI layer realizes data generation and monitoring. The intermediate layer is a data processing and transmission. Device control layer performs data output of the power supply. We use ARM + DSP controller designed by ourselves for controlling the power supply output. At the same time, we have adopted the FPGA controller designed for timing for power supply control in order to meet the requirements of accelerator synchronized with the output of the power supply.

Experimental facilities like synchrotrons and free electron lasers, often aim at well defined data workflows tightly integrated with their control systems. Still such facilities are also service providers to visiting scientists. The hosted researchers often have requirements different than those present in the established processes. The most evident needs are those for i) flexible experimental data visualisation, ii) rapid prototyping of analysis methods, and iii) electronic logbook services. This paper reports on the development of a software system, collectively referred to as DonkiTools, that aims at satisfying the aforementioned needs for the synchrotron ELETTRA and the free electron laser FERMI. The design strategy is outlined and includes topics regarding: dynamic data visualisation, Python scripting of analysis methods, integration with the TANGO distributed control system, electronic logbook with automated metadata reporting, usability, customization, and extensibility. Finally a use case presents a full deployment of the system, integrated with the FermiDAQ data collection system, in the free electron laser beamline EIS-TIMEX.

CERN, Geneva, Switzerland

With the wide-spread use of asynchronous web communication mechanisms like WebSockets and WebRTC, it has now become possible to distribute industrial controls data originated in field devices or SCADA software in a scalable and event-based manner to a large number of web clients in the form of rich interactive visualizations. There is however no simple, secure and performant way yet to query large amounts of aggregated historical data. This paper presents an implementation of a tool, able to make massive quantities of pre-indexed historical data stored in ElasticSearch available to a large amount of web-based consumers through asynchronous web protocols. It also presents a simple, Opensocial-based dashboard architecture, that allows users to configure and organize rich data visualizations (based on Highcharts Javascript libraries) and create navigation flows in a responsive mobile-friendly user interface. Such techniques are used at CERN to display interactive reports about the status of the LHC infrastructure (e.g. vacuum or cryogenics installations) and give access to fine-grained historical data stored in the LHC Logging database in a matter of seconds.

L. Gallerani
CERN, Geneva, Switzerland

The CERN Technical Network (TN) TN was intended to be a network for accelerator and infrastructure operations. However, today, more than 60 Million IP packets are routed every hour between the General Purpose Network (GPN) and the TN involving more than 6000 different hosts. In order to improve the security of the accelerator control system, it is fundamental to understand the network traffic between the two networks in order to define appropriate routing and firewall rules without impacting Operations. The complexity and huge size of the infrastructure and the number of protocols and services involved have discouraged for years any attempt to understand and control the network traffic between the GPN and the TN. In this talk, we will show a new way to solve the problem graphically. Combining the network traffic analysis with the use of large graph visualization algorithms we produce comprehensible and usable 2D large colour topology graphs mapping the complex network relations of the control system machines and services in a detail and clarity never seen before. The talk integrates very interesting pictures and video of the graphical analysis attempt.

The Post Mortem service for CERNs accelerator complex stores and analyses transient data recordings of various equipment systems following certain events, like a beam dump or magnet quenches. The main purpose of this framework is to provide fast and reliable diagnostic to the equipment experts and operation crews to decide whether accelerator operation can continue safely or whether an intervention is required. While the Post Mortem System was initially designed to serve CERNs Large Hadron Collider (LHC), the scope has been rapidly extended to include as well External Post Operational Checks and Injection Quality Checks in the LHC and its injector complex. These new use cases impose more stringent time-constraints on the storage and analysis of data, calling to migrate the system towards better scalability in terms of storage capacity as well as I/O throughput. This paper presents an overview on the current service, the ongoing investigations and plans towards a scalable data storage solution and API, as well as the proposed strategy to ensure an entirely smooth transition for the current Post Mortem users.

ANKA realized a new unified archiving system for the typical synchrotron control systems by integrating their logging databases into the "Advanced Data Extraction Infrastructure" (ADEI). ANKA's control system environment is heterogeneous: some devices are integrated into the Tango archiving system, other sensors are logged by the Supervisory Control and Data Acquisition (SCADA) system WinCC OA. For both systems modules exist to configure the pool of sensors to be archived in the individual control system databases. ADEI has been developed to provide a unified data access layer for large time-series data sets. It supports internal data processing, caching, data aggregation and fast visualization in the web. Intelligent caching strategies ensure fast access even to huge data sets stored in the attached data sources like SQL databases. With its data abstraction layer the new ANKA archiving system is the foundation for automated monitoring while keeping the freedom to integrate nearly any control system flavor. The ANKA archiving system has been introduced successfully at three beamlines. It is operating stable since about one year and it is intended to extend it to the whole facility.

The European X-ray Free Electron Laser is a high-intensity X-ray light source currently being constructed in the area of Hamburg, that will provide spatially coherent X-rays in the energy range between 0.25 keV and 25 keV. The machine will deliver 10 trains/s, consisting of up to 2700 pulses, with a 4.5 MHz repetition rate. The LPD, DSSC and AGIPD detectors are being developed to provide high dynamic-range Mpixel imaging capabilities at the mentioned repetition rates. A consequence of these detector characteristics is that they generate raw data volumes of up to 15 Gbyte/s. In addition the detector's on-sensor memory-cell and multi-/non-linear gain architectures pose unique challenges in data correction and calibration, requiring online access to operating conditions and control settings. We present how these challenges are addressed within XFEL's control and analysis framework Karabo, which integrates access to hardware conditions, acquisition settings (also using macros) and distributed computing. Implementation of control and calibration software is mainly in Python, using self-optimizing (py) CUDA code, numpy and iPython parallels to achieve near-real time performance for calibration application.

The radiofrequency and transverse damper feedback systems of the Large Hadron Collider digitize beam phase and position measurements at the bunch repetition rate of 40 MHz. Embedded memory buffers allow a few milliseconds of full rate bunch-by-bunch data to be retrieved over the VME bus for diagnostic purposes, but experience during LHC Run I has shown that for beam studies much longer data records are desirable. A new "observation box" diagnostic system is being developed which parasitically captures data streamed directly out of the feedback hardware into a Linux server through an optical fiber link, and permits processing and buffering of full rate data for around one minute. The system will be connected to an LHC-wide trigger network for detection of beam instabilities, which allows efficient capture of signals from the onset of beam instability events. The data will be made available for analysis by client applications through interfaces which are exposed as standard equipment devices within CERN's controls framework. It is also foreseen to perform online Fourier analysis of transverse position data inside the observation box using GPUs with the aim of extracting betatron tune signals.

The MeerKAT telescope, under construction in South Africa, is comprised of a large set of elements. The elements expose various sensors to the Control and Monitoring (CAM) system, and the sampling strategy set by CAM per sensor varies from several samples a second to infrequent updates. This creates a substantial volume of sensor data that needs to be stored and made available for analysis. We depict the flow of sensor data through the CAM system, showing the various memory buffers, temporary disk storage and mechanisms to permanently store the data in HDF5 format on the network attached storage (NAS).

The automation infrastructure needed to reliably run CERN's accelerator complex and its experiments produces large and diverse amounts of data, besides physics data. Over 600 industrial control systems with about 45 million parameters store more than 100 terabytes of data per year. At the same time a large technical expertise in this domain is collected and formalized. The study is based on a set of use cases classified into three data analytics domains applicable to CERN's control systems: online monitoring, fault diagnosis and engineering support. A known root cause analysis concerning gas system alarms flooding was reproduced with Siemens' Smart Data technologies and its results were compared with a previous analysis. The new solution has been put in place as a tool supporting operators during breakdowns in a live production system. The effectiveness of this deployment suggests that these technologies can be applied to more cases. The intended goals would be to increase CERN's systems reliability and reduce analysis efforts from weeks to hours. It also ensures a more consistent approach for these analyses by harvesting a central expert knowledge base available at all times.

Integrating Web-Based User Interface Within Cern's Industrial Control System Infrastructure

CERN, Geneva, Switzerland

For decades the user interfaces of industrial control systems have been primarily based on native clients. However, the current IT trend is to have everything on the web. This can indeed bring some advantages such as easy deployment of applications, extending HMIs with turnkey web technologies, and apply to supervision interfaces the interaction model used on the web. However, this also brings its share of challenges: security management, ability to spread the load and scale out to many web clients, etc… In this paper, the architecture of the system that was devised at CERN to decouple the production WINCC-OA based supervision systems from the web frontend and the associated security implications are presented together with the transition strategy from legacy panels to full web pages using a stepwise replacement of widgets (e.g. visualization widgets) by their JavaScript counterpart. This evolution results in the on-going deployment of web-based supervision interfaces proposed to the operators as an alternative for comparison purposes.

ANSTO, Menai, New South Wales, Australia

Scripting is an important feature of instrument control software. It allows scientists to execute a sequence of tasks to run complex experiments, and it makes a software developers' life easier when testing and deploying new features. Modern instrument control applications require easy to develop and reliable scripting support. At ANSTO we provide a Python scripting interface for Gumtree. Gumtree is an application that provides three features; instrument control, data treatment and visualisation for neutron scattering instruments. The scripting layer has been used to coordinate these three features. The language is simple and well documented, so scientists require minimal programming experience. The scripting engine has a web interface so that users can use a web browser to run scripts remotely. The script interface has a numpy-like library that makes data treatment easier. It also has a GUI library that automatically generates control panels for scripts. The same script can be loaded in both the workbench (desktop) application and the web service application for online data treatment. In both cases a GUI will be generated with similar look and feel.

The variety of motion control applications on existing and future NSLS-II beam lines demand custom control electronics developed to meet specific needs and ease integration to existing systems. Thus an encoder interface was designed for a number of detection techniques that require fly-scan applications. This design fits in a 2U chassis and can handle up to 4 incremental quadrature encoders with a digital RS-422A interface and output frequencies up to 10 MHz. The logic, based on Xilinx Virtex-6 FPGA, processes signals from an encoder, associates it with accelerator timestamp and sends the data to a server using TCP/IP stack, with the server side running an EPICS IOC. Several filtering and compression techniques are also applied. The device then re-translates the interface signals for the motion controller, allowing the device to be installed between encoder and motion controller with no interference to the system. The hardware leverages the NSLS-II BPM Digital Front End (DFE) board with Virtex-6 FPGA and periphery. The design harmoniously complements the family of NSLS-II equipment sharing same mechanical and electrical platform.

Low current measurements developments have been pointed out as strategic for ALBA synchrotron. From the first day of operation of the seven Beamlines currently in operation ALBA Em electrometer this has been successfully used. Today, the two new beamlines of Phase 2 that are being constructed and the new end stations have required specification changes in terms of increased accuracy, capability of synchronization, timestamping, management of large buffers and high performance closed-loop implementation. The scheme of full custom hardware design has been abandoned. ALBA Em# project approach has been based in the selection of industry standard interfaces: FMC boards design for custom needs, FMC carrier over PCIe using SPEC board from CERN under OHWR license, and Single Board Computer using PCIe to implement interfaces with the control system. This Paper describes the new design of the Electrometers at Alba, suited for the newer requirements, more flexible, performing and maintainable, which profits from the know-how acquired with previous versions and suits the new data acquisition paradigm emerged with the standardization of quick continuous scans and data acquisition.

There were more than 2500 magnet power supplies for KEKB storage rings and injection beam transport lines. For the remote control of such a large number of power supplies, the Power Supply Interface Controller Module (PSICM), which is plugged into each power supply, was developed. It has a microprocessor, ARCNET interface, trigger signal input interface, and parallel interface to the power supply. The PSICM is not only an interface card but also controls synchronous operation of the multiple power supplies with an arbitrary tracking curve. For SuperKEKB we have developed the upgraded version of the PSICM. It has the fully backward compatible interface to the power supply. The enhanced features includes high speed ARCNET communication and redundant trigger signals. Towards the phase 1 commissioning of SuperKEKB, the construction of the magnet control system is ongoing. First mass production of 1000 PSICMs has been completed and their installation is in progress. The construction status of the magnet control system is presented in this paper.

ZYNQ is the new architecture of FPGA with dual high performance ARM Cortex-A9 processors from Xilinx. A new module with Giga Bit Ethernet interface based on the ZYNQ XC7Z010 is development for the High Purity Germanium Detectors' data acquisition in the CJPL (China JingPing under-ground Lab) experiment, which is named as RAIN1000Z1. Base on the nice RAIN1000Z1 hardware platform, EPICS is porting on the ARM Cortex-A9 processor with embedded Linux and an Input Output Controller is implemented on the RAIN1000Z1 module. Due to the combination of processor and logic and new silicon technology of ZYNQ, embedded Linux with TCP/IP sockets and real time high throughput logic based on VHDL are running in a single chip with small module hardware size, lower power and higher performance. This paper will introduce how to porting the EPICS IOC application on the ZYNQ based on embedded Linux and give a demo of IO control and RS232 communication.

The correctness of the software used in control systems has been always a high priority, as a failure can cause serious expenses, injuries or loss of reputation. To improve the quality of these applications, various development and verification methods exist. All of them necessitate a deep understanding of the requirements which can be achieved by a well-adapted formal specification method. In this paper we introduce a state machine and data-flow-based formal specification method tailored to PLC modules. This paper presents the practical benefits and new possibilities of this method, comprising consistency checking, PLC code generation, and checking equivalence between the specification and its previous versions or legacy code. The usage of these techniques can improve the level of understanding of the requirements and increase the confidence in the correctness of the implementation. Furthermore, they can help to apply formal verification techniques by providing formalised requirements.

CERN, Geneva, Switzerland

Model checking is a promising formal verification method to complement testing in order to improve the quality of PLC programs. However, its application typically needs deep expertise in formal methods. To overcome this problem, we introduce PLCverif, a tool that builds on our verification methodology and hides all the formal verification-related difficulties from the user, including model construction, model reduction and requirement formalisation. The goal of this tool is to make model checking accessible to the developers of the PLC programs. Currently, PLCverif supports the verification of PLC code written in ST (Structured Text), but it is open to other languages defined in IEC 61131-3. The tool can be easily extended by adding new model checkers.

CX control system is used at VEPP-5 and several other BINP facilities. CX version 4 is designed to provide more flexibility and enable interoperability with other control systems. In addition to device drivers, most of its components are implemented in a modular fashion, including data access at both client and server sides. The server itself is a library. This approach allows clients to access several different control systems simultaneously and natively (without any gateways). CXv4 servers are able to provide data access to clients from diverse CS architectures/protocols, subject to appropriate network module being loaded. The server library, coupled with "null link" client-server access module, allows to create standalone monolythic programs for specific small applications (such as test benches and device test screens/utilities) using the same ready code from large-scale control system but without its complexity. CXv4 design principles and solutions are discussed and first deployment results are presented.

At CERN there are currently about 200 ventilation air handling units in production, used in many different applications, including building ventilation, pressurization of safe rooms, smoke extraction, pulsion/extraction of experimental areas (tunnel, cavern, etc), and the ventilation of the computing centre. The PLC applications which operate these installations are currently being revamped to a new framework (UNICOS CPC). This work began 3 years ago, and we are now in a position to standardize the development of these HVAC applications, in order to reduce the cost of initial development (including specification and coding), testing, and long-term maintenance of the code. In this paper the various improvements to the process with be discussed, and examples will be shown, which can thus help the community develop HVAC applications. Improvements include templates for the "Functional Analysis" specification document, standardized HVAC devices and templates for the PLC control logic, and automatically generated test documentation, to help during the Factory Acceptance Test (FAT) and Site Acceptance Test (SAT) processes.

The new injection complex for VEPP-4 and VEPP-2000 e-p colliders is under construction at Budker Institute, Novosibirsk, Russia. The double-direction bipolar transfer line K-500 of 130 and 220 meters length respectively will provide the beam transportation from the injection complex to the colliders with a frequency of 1 Hz. The designed number of particles in the transferred beam is 2*10¹⁰ of electrons or positrons, the energy is 500 MeV. K-500 has dozens of types of magnets, power supplies and electronic devices. It is rather complicated task to store and manage information about such a number of types and instances of entities, especially to handle relations between them. This knowledge is critical for configuration of all aspects of control system. Therefore we have chosen PyCDB to handle this information and automate configuration data extraction for different purposes starting with reports and diagrams and ending with high-level applications and EPICS IOCs' configuration. This paper considers concepts of this approach and shows the PyCDB database sctructure designed for K-500 transfer line. An automatic configuration of IOCs is described as integration with EPICS.

Funding: This work was supported by the U.S. Department of Energy under contract No. DE-AC02-07CH11359
Developers of real-time embedded software often need to build the operating system kernel, tools and supporting applications from source to work with the differences in their hardware configuration. The first attempt to introduce Linux-based real-time embedded systems into the Fermilab accelerator controls system used this approach but it was found to be time-consuming, difficult to maintain and difficult to adapt to different hardware configurations. Buildroot is an open source build system with a menu-driven configuration tool (similar to the Linux kernel build system) that automates this process. A customized Buildroot system has been developed for use in the Fermilab accelerator controls system that includes several hardware configuration profiles (including Intel, ARM and PowerPC) and packages for Fermilab support software. A bootable image file is produced containing the Linux kernel, shell and supporting software suite that varies from 3 to 20 megabytes large ' ideal for network booting. The result is a platform that is easier to maintain and deploy in diverse hardware configurations.

The SKA Telescope Manager (SKA. TM) is a distributed software application aimed to control the operation of thousands of radio telescopes, antennas and auxiliary systems (e.g. infrastructures, signal processors, …) which will compose the Square Kilometre Array, the world's largest radio astronomy facility currently under development. SKA. TM, as an "element" of the SKA, is composed in turn by a set of sub-elements whose tight coordination is ensured by a specific sub-element called "Local Monitoring and Control" (TM.LMC). TM.LMC is mainly focussed on the life cycle management of TM, the acquisition of every network-related information useful to understand how TM is performing and the logging library for both online and offline sub-elements. Given the high complexity of the system, identifying the origin of an issue, as soon as a problem occurs, appears to be a hard task. To allow a prompt diagnostics analysis by engineers, operators and software developers, a Knowledge-Based System (KBS) approach is proposed and described for the logging service.

DRAMA 2 - An Evolutionary Leap for the DRAMA Environment for Instrumentation Software Development

status, interface, software, GUI

AAO, North Ryde, Australia

The DRAMA Environment provides an API for distributed instrument software development. It originated at the Anglo-Australian Observatory (now Australian Astronomical Observatory) in the early 1990s, in response to the need for a software environment for large distributed and heterogeneous systems, with some components requiring real-time performance. It was first used for the AAO's 2dF fibre positioner project for the Anglo-Australian Telescope. 2dF is still in use today, but has changed dramatically over time. DRAMA is used for other AAO systems and is or has been used at various other observatories looking for a similar solution. Whilst DRAMA has evolved and many features were added, there had been no big changes. It was still a largely C language based system, with some C++ wrappers. It did not provide good support for threading or exceptions. Ideas for proper thread support within DRAMA have been in development for some years, but C++11 has provided many features which allow a high quality implementation. The opportunity provided by C++11 has been taken to make significant changes to the DRAMA API, producing a modern and more reliable interface to DRAMA, known as DRAMA2.

M. Hager, M. Regodic
EBG MedAustron, Wr. Neustadt, Austria

The commissioning and operation of an accelerator requires a large set of supportive applications. Especially in the early stages, these tools have to work with unfinished and changing systems. To allow the implementation of applications that are dynamic enough for this environment, a dedicated software architecture, the Operational Application (OpApp) architecture, has been developed at MedAustron. The main ideas of the architecture are a separation of functionality into reusable execution modules and a flexible and intuitive composition of the modules into bigger modules and applications. Execution modules are implemented for the acquisition of beam measurements, the generation of cycle dependent data, the access to a database and other tasks. On this basis, Operational Applications for a wide variety of use cases can be created, from small helper tools to interactive beam commissioning applications with graphical user interfaces. This contribution outlines the OpApp architecture and the implementation of the most frequently used applications.

Solving the Synchronization Problem in Multi-Core Embedded Real-Time Systems

real-time, operation, embedded, hardware

942

F. Hoguin, S. Deghaye
CERN, Geneva, Switzerland

Multi-core CPUs have become the standard in embedded real-time systems. In such systems, where several tasks run simultaneously, developers can no longer rely on high priority tasks blocking low priority tasks. In typical control systems, low priority tasks are dedicated to receiving settings from the control room, and high priority real-time tasks, triggered by external events, control the underlying hardware based on these settings. Settings' correctness is of paramount importance and they must be modified atomically from a real-time task point of view. This is not feasible in multi-core environments using classic double-buffer approaches, mainly because real-time tasks can overlap, preventing buffer swaps. Other common synchronization solutions involving locking critical sections introduce unpredictable jitter on real-time tasks, which is not acceptable in CERN's control system. A lock-free, wait-free solution to this problem based on a triple buffer, guaranteeing atomicity no matter the number of concurrent tasks, is presented. The only drawback is potential synchronization delay on contention. This solution has been implemented and tested in CERN's real-time C++ framework.

Accurate control of power converters is a vital activity in large physics projects. Several different control scenarios may coexist, including regulation of a circuit's voltage, current, or field strength within a magnet. Depending on the type of facility, a circuit's reference value may be changed asynchronously or synchronously with other circuits. Synchronous changes may be on demand or under the control of a cyclic timing system. In other cases, the reference may be calculated in real-time by an outer regulation loop of some other quantity, such as the tune of the beam in a synchrotron. The power stage may be unipolar or bipolar in voltage and current. If it is unipolar in current, it may be used with a polarity switch. Depending on the design, the power stage may be controlled by a firing angle or PWM duty-cycle reference, or a voltage or current reference. All these different cases are supported by the CERN Converter Control Libraries (CCLIBS), which are open-source C libraries that include advanced reference generation and regulation algorithms. This paper introduces the libraries and reviews their origins, current status and future.

JASRI/SPring-8, Hyogo-ken, Japan

MADOCA II is a next generation of Message And Database Oriented Control Architecture (MADOCA) and implemented into control system of SPring-8 and SACLA data acquisition (DAQ) system since 2013. In 2014, SACLA introduced a third beam line to increase the capacity of experiments. Then sophisticated control architecture needed to be developed to prevent miss operations among beamlines. In this paper, multi-host message routing in MADOCA II and its application to SALCA DAQ system to solve the problem is presented. In SACLA DAQ system, a master server was added which intermediates control messages between clients and equipment management servers. Since the access control can be centralized to the master server, reliable operation can be had by avoiding the influence by accidental modification of DAQ setting by end-users. The multi-host message routing was implemented to add an extension in MADOCA II by forwarding specific message objects to other hosts. Some technical issues related to messaging loop and time delay, are also addressed. It is also planned to utilize this technique to other cases in BL at SPring-8 where access control under firewall is required.

Moreover, a low cost embedded board has been recently adopted to fulfill the control requirements of distributed instrumentation. These facts lead to the necessity of managing several releases of the operating system, kernel and libraries, and finally to the decision of adopting a comprehensive unified approach based on a common codebase: the Yocto Project. Based on Yocto Project, a control system oriented GNU/Linux distribution called 'Flop' has been created. The complete management of the software chain, the ease of upgrading or downgrading complete systems, the centralized management and the platform-independent deployment of the user software are the main features of Flop.

In PAL-XFEL, a 4th generation light source, the HLS (Ultrasonic-type Hydrostatic Levelling System) developed at BINP (Budker Institute of Nuclear Physics) in Russia was installed and operated in all parts of PAL-XFEL in order to maintain observations of the vertical change building floor by the ground sinking and uplifting. For this, a HLS measuring program was written using NI LabVIEW and an EPICS IOC Server was built using the CA Lab which has been developed at BESSY (Berlin Electron Storage Ring Society for Synchrotron Radiation) in Germany. The CA Lab was improved and verified in order to confirm that it could support EPICS BASE libraries V3.14.12, and EPICS CA Client and that the EPICS IOC Server could be easily constructed by CA Lab in a 64-bit LabVIEW. This made Multi-core CPU (Multi-core Processor / Multi-thread Program) resource of 64bit Computer System (64bit Hardware PC / 64bit Windows OS / 64bit LabVIEW Multi-thread Programming) to be 100 percent utilized. This study proposes a configuration process for the HLS measuring program algorithm and a building process for the EPICS IOC Server by using CA Lab.

The KAT-7 and MeerKAT radio telescope control systems (www.ska.ac.za) are built on a rich Python architecture. At its core, we use KATCP (Karoo Array Telescope Communications Protocol), a text-based protocol that has served the projects very well. KATCP is supported by every device and connected software component in the system. However, its original implementation relied on threads to support asynchronous operations, and this has sometimes complicated the evolution of the software. Since MeerKAT (with 64 dishes) will be much larger and more complex than KAT-7, the Control and Monitoring (CAM) team investigated some alternatives to classical threading. We have adopted Tornado (www.tornadoweb.org) as the asynchronous engine for KATCP. Tornado, popular for Web applications, is built on a robust and very efficient coroutine paradigm that in turn is based on Python's generators. Co-routines avoid the complexity of thread re-entrancy and lifetime management, resulting in cleaner and more maintainable user code. This paper will describe our migration to a Tornado co-routine architecture, highlighting the benefits and some of the pitfalls and implementation challenges we have met.

The beam commissioning of J-PARC started in November, 2006. Since then, the timing system of J-PARC accelerator complex has contributed stable beam operations of three accelerators: a 400-MeV linac (LI), a 3-GeV rapid cycling synchrotron (RCS), and a 50-GeV synchrotron (MR). The timing system handles two different repetition cycles: 25 Hz for LI and RCS, and 2.48-6.00 sec. for MR (MR cycle). In addition, the timing system is capable to provide beams to two different experimental facilities in single MR cycle: Material and Life Science Experimental Facility (MLF) and Neutrino Experimental Facility (NU), or, MLF and Hadron Experimental Facility (HD). Recently, a plan to introduce a new facility, Accelerator-Driven Transmutation Experimental Facility (ADS), around 2018, has been discussed. Studies for the timing system upgrade are started: change of the master repetition rate from 25Hz to 50 Hz, and a scheme to provide beams to three different experimental facilities in single MR cycle (MLF, NU and ADS or MLF, HD and ADS). This paper reviews the 8-year operation experience of the J-PARC timing system, followed by a present perspective of upgrade studies.

RAON is a particle accelerator to research the interaction between the nucleus forming a rare isotope as Korean heavy-ion accelerator. RAON accelerator consists of a number of facilities and equipments as a large-scaled experimental device operating under the distributed environment. For synchronization control between these experimental devices, timing system of the RAON uses the VME-based EVG/EVR system. In order to test the high-speed performance of the control logic with the minimized event signal delay, it is planned to establish the step motor controller testbed applying the FPGA chip. The testbed controller will be configured with Zynq 7000 series of Xilinx FPGA chip. Zynq as SoC (System on Chip) is divided into PS (Processing System) with PL (Programmable Logic). PS with the dual-core ARM cpu is performing the high-level control logic at run-time on linux operating system. PL with the low-level FPGA I/O signal interfaces with the step motor controller with the event signal received from timing system. This paper describes the content and performance evaluation obtained from the step motor control through the various synchronized event signal received from the timing system.

Synchronization is a crucial concern in distributed measurement and control systems. White Rabbit provides sub-nanosecond accuracy and picoseconds precision for large distributed systems. In the Large High Altitude Air Shower Observatory project, to guarantee the angular resolution of reconstructed air shower event, a 500 ps overall synchronization precision must be achieved among thousands of detectors. A small prototype built at Yangbajin, Tibet, China has been working well for a whole year. A portable calibration node directly synced with the grandmaster switch and a simple detectors stack named Telescope are used to verify the overall synchronization precision of the whole prototype. The preliminary experiment results show that the long term synchronization of the White-Rabbit network is promising and 500 ps overall synchronization precision is achievable with node by node calibration and temperature correction.

CERN, Geneva, Switzerland

At CERN, fast pulsed magnet (kicker) systems are used to inject, extract, dump and excite beams. Depending on their operational functionalities and as a result of the evolution of controls solutions over time, the timing controls of these systems were based on hybrid hardware architectures that have resulted in a large disparity of software solutions. In order to cure this situation, a Kicker Timing Software (KiTS), based on a modular hardware and software architecture, has been developed with the objective to increase the homogeneity of fast and slow timings control for all types of fast pulsed magnet systems. The KiTS uses a hardware abstraction layer and a configurable software model implemented within the Front-End Software Architecture (FESA) framework. It has been successfully deployed in the control systems of the different types of kicker systems at CERN like for the PS continuous transfer, the SPS injection and extraction, the SPS tune measurement and the LHC injection.

CAFE (Channel Access interFacE) is a C++ client library that offers a comprehensive and easy-to-use Channel Access (CA) interface to the Experimental Physics and Industrial Control System (EPICS). The code base has undergone significant refactoring to make the internal structure more comprehensible and easier to interpret, and further methods have been implemented to increase its flexibility in readiness to serve as the CA host in fourth-generation and scripting languages for use at the SwissFEL, Switzerland's X-ray Free-Electron Laser facility. A number of specific design features are presented, including policies that provide control over configurable components that govern the behaviour of interactions, and the methodology that guarantees that the outcome of all remote method invocations are captured with integrity in every eventuality, thereby ensuring reliability and stability. An account is also given on newly created bindings for the Cython programming language, which offers a major performance improvement to Python developers, and on an update to CAFE's MATLAB Executable (MEX) file.

A mature control system will provide central services such as alarm handling, archiving, location and naming, debugging, etc. along with development tools and administrative utilities. It has become common to refer to the collection of these services as a 'studio'. Indeed Control System Studio (CSS)* strives to provide such services independent of the control system protocol. Such a 'one-size-fits-all' approach is likely, however, to focus on features and behavior of the most prominent control system protocol in use, providing a good fit there but perhaps offering only a rudimentary fit for 'other' control systems. TINE** is for instance supported by CSS but is much better served by making use of TINE Studio. This paper reports here on the rich set of services and utilities comprising TINE Studio.

Analysis of accelerator data has traditionally been done using custom tools, either developed locally or at other laboratories. The actual data repositories are openly available to all users, but it can take significant effort to mine the desired data, especially as the volume of these repositories increases to hundreds of terabytes or more. Much of the data analysis is done in real time when the data is being logged. However, sometimes users wish to apply improved algorithms, look for data correlations, or perform more sophisticated analysis. There is a wide spectrum of desired analytics for this small percentage of the problem domains. In order to address this tools have been built that allow users to efficiently pull data out of the repositories but it is then left up to them to post process that data. In recent years, the use of tools to bridge standard analysis systems, such as Matlab, R, or SciPy, to the controls data repositories, has been investigated. In this paper, the tools used to extract data from the repositories, tools used to bridge the repositories to standard analysis systems, and directions being considered for the future, will be discussed.

Applications used for Collider-Accelerator Controls at Brookhaven National Laboratory typically run as console level programs on a Linux operating system. One essential requirement for accelerator controls applications is bidirectional synchronized IO data communication. Several new web frameworks (Vaadin, GXT, node.js, etc.) have made it possible to develop web based Accelerator Controls applications that provide all the features of console based UI applications that includes bidirectional IO. Web based applications give users flexibility by providing an architecture independent domain for running applications. Security is established by restricting access to users within the local network while not limiting this access strictly to Linux consoles. Additionally, the web framework provides the opportunity to develop mobile device applications that makes it convenient for users to access information while away from the office. This paper explores the feasibility of using the Vaadin web framework for developing UI applications for Collider-Accelerator controls at Brookhaven National Laboratory.

Since commissioning, Diamond Light Source has used the Extensible Display Manager (EDM) to provide a GUI to its EPICS-based control system. As Linux moves away from X-Windows the future of EDM is uncertain, leading to the evaluation of Control System Studio (CS-Studio) as a replacement. Diamond has a user base accustomed to the interface provided by EDM and an infrastructure designed to launch the multiple windows associated with it. CS-Studio has been adapted to provide an interface that is similar to EDM's while keeping the new features of CS-Studio available. This will allow as simple as possible a transition to be made to using CS-Studio as Diamond's user interface to EPICS. It further opens up the possibility of integrating the control system user interface with those in the Eclipse based GDA and DAWN tools which are used for data acquisition and data analysis at Diamond.

1036

R. Martini, M. Bräger, J.L. Salmon, A. Suwalska
CERN, Geneva, Switzerland

The monitoring of the technical infrastructure at CERN relies on the quality of the definition of numerous and heterogeneous data sources. In 2006, we introduced the MoDESTI* procedure for the Technical Infrastructure Monitoring** (TIM) system to promote data quality. The first step in the data integration process is the standardisation of the declaration of the various data points whether these are alarms, equipment statuses or analogue measurement values. Users declare their data points and can follow their requests, monitoring personnel ensure the infrastructure is adapted to the new data, and control room operators check that the data points are defined in a consistent and intelligible way. Furthermore, rigorous validations are carried out on input data to ensure correctness as well as optimal integration with other computer systems at CERN (maintenance management, geographical viewing tools etc.). We are now redesigning the MoDESTI procedure in order to provide an intuitive and streamlined Web based tool for managing data definition, as well as reducing the time between data point integration requests and implementation. Additionally, we are introducing a Class-Device-Property data definition model, a standard in the CERN accelerator sector, for a more flexible use of the TIM data points.

On the DESY campus Matlab is a widely used tool for creating complex user interfaces. Although the on-board GUI tools are easy to use and provide quick results, the generated low-level code lacks uniformity and advanced features like automatic verification and conversion of input and output data. These limitations are overcome by the newly developed DataGUI library. The library is based on the model-view-controller software pattern and supports enhanced data handling, undocumented Matlab GUI elements, and configurable resizing of the user interface. An outlook on features of the upcoming release is also presented.

In the framework of delivering control system services to the Solaris synchrotron light source, Kraków, Poland, Cosylab realized a comprehensive set of controls GUIs, using a structured approach. The goals of using this architecture are threefold. The first is to achieve reliable, predictable and consistent behaviour of the controls software. The second is that it is easy to deploy and maintain through scripting. The third is that it is future-proof by providing extensibility, using dedicated templates. The system is based on a configuration database, populated with devices, device specifics and device groups (clusters of devices performing specific operations). The GUIs are dynamically generated from this configuration. For the synoptic views, TANGO-standard JDraw and its configuration are integrated into the framework. Existing GUIs, written in PyTango can be easily adapted to function as part of this system. The compelling user benefits are high usability and life-time management through controlled upgrade and extension. For new big physics projects this GUI control program offers a customizable solution for any TANGO based control system.

ESS, Lund, Sweden

To help developers create consistent-looking control system application GUIs, the European Spallation Source Integrated Control Systems group asked Cosylab to develop a Style Guide document. Its purpose is to avoid that GUIs needlessly diverge and make the end-result of all screens combined look harmonious, even if GUIs have been developed over several years by many contributors. Also it will speed up development, by letting developers start from design patterns, rather than starting "from a blank page". The document defines a set of basic panel sizes, containing a 960px-style grid for consistent organization of content. It also defines color scheme and font usage, in-line with the overall ESS corporate communications manual, with the addition of signal colors. In addition it shows example screens to serve as GUI design patterns for typical screen types such as engineering screens, control applications and synoptic screens. It concludes by setting rules and recommendations for the usage of automation symbols and display of engineering and physical units. The document is further complemented by a separate document with Usability Guidelines for Human-Machine interfaces.

The ALICE experiment is a complex hardware and software device, monitored and operated with a control system based on WinCC OA. ALICE is composed of 19 detectors and installed in a cavern along the LHC at CERN; each detector is a set of modular elements, assembled in a hierarchical model called Finite State Machine. A 3-D model of the ALICE detector has been realized, where all elements of the FSM are represented in their relative location, giving an immediate overview of the status of the detector. For its simplicity, it can be a useful tool for the training of operators. The development is done using WinCC OA integrated with the JCOP fw3DViewer, based on the AliRoot geometry settings. Extraction and conversion of geometry data from AliRoot requires the usage of conversion libraries, which are currently being implemented. A preliminary version of ALICE 3-D is now deployed on the operator panel in the ALICE Run Control Centre. In the next future, the 3-D panel will be available on a big touch screen in the ALICE Visits Centre, providing visitors with the unique experience of navigating the experiment from both inside and out.

TANGO is a distributed Control System with an active community of developers. The community features multiple services like Archiving or Alarms with an heterogeneous mix of technologies and look-and-feels that must be integrated in the final user workflow. The Viewer and Commander Control Application (VACCA) was developed on top of Taurus to provide TANGO with the user experience of a commercial SCADA, keeping the advantages of open source. The Taurus GUI application enables scientists to design their own live applications using drag-and-drop from the widget catalog. The VACCA User Interface provides a template mechanism for synoptic-driven applications and extends the widget catalog to interact with all the components of the control system (Alarms, Archiving, Databases, Hosts Administration). The elements of VACCA are described in this paper, as well as its mechanisms to encapsulate all services in a GUI for an specific subsystem (e.g. Vacuum).

DESY, Hamburg, Germany

JAVA DOOCS Data Display (JDDD) is the standard tool for developing control system panels for the FLASH facility and European XFEL. The panels are mainly started on DESY campus. For remote monitoring and expert assistance a secure, fast and light-weight access method is required. One possible solution is using HTML5 as transport protocol, because it is available on many common platforms including mobile ones. For this reason an HTML5 version of JDDD, running in a Tomcat application server, was developed. WebSocket technology is used to transfer the panel image to the browser. In the other direction, mouse events are sent back from the browser to the Tomcat server. Now thousands of existing JDDD panels can be accessed from remote using standard web technology. No special browser plugins are required. This article discusses the general issues of the web-based interaction with the control system such as security, usability, network traffic and scalability, and presents the WebSocket approach.

The TANGO archiving system HDB++ continuously stores data over time into the historical database. The new time-machine application, a specialization of the extensively used save/restore framework, allows bringing back sets of control system variables to their values at a precise date and time in the past. Given the desired time stamp t0 and a set of TANGO attributes, the values recorded at the most recent date and time preceding or equaling t0 are fetched from the historical database. The user can examine the list of variables with their values before performing a full or partial restoration of the set. The time-machine seamlessly integrates with the well known save/restore application, sharing many of its characteristics and functionalities, such as the matrix-based subset selection, the live difference view and the simple and effective user interface.

XFEL. EU, Hamburg, Germany

The Karabo GUI is a generic graphical user interface (GUI) which is currently developed at the European XFEL GmbH. It allows the complete management of the Karabo distributed control and data acquisition system. Remote applications (devices) can be instantiated, operated and terminated. Devices are listed in a live navigation view and from the self-description inherent to every device a default configuration panel is generated. The user may combine interrelated components into one project. Such a project includes persisted device configurations, custom control panels and macros. Expert panels can be built by intermixing static graphical elements with dynamic widgets connected to parameters of the distributed system. The same panel can also be used to graphically configure and execute data analysis workflows. Other features include an embedded IPython scripting console, logging, notification and alarm handling. The GUI is user-centric and will restrict display or editing capability according to the user's role and the current device state. The GUI is based on PyQt technology and acts as a thin network client to a central Karabo GUI-Server.

The control system for TRIUMF's upgraded secondary beam line M20 was implemented by using a PLC and one of many EPICS IOCs running on a multi-core Dell server. Running the IOC on a powerful machine rather than on a small dedicated computer has a number of advantages such as fast code execution and the availability of a large amount of memory. A large EPICS database can be loaded into the IOC and used for visualization of the interlocks implemented in the PLC. The information about interlock status registers, text messages, and the names of control and interlock panels are entered into a relational database by using a web browser. Top-level EPICS schematics are generated from the relational database. For visualization the embedded windows available in the Extensible Display Manager (EDM) are the EPICS clients, which retrieve interlock status information from the EPICS database. A set of interlock panels is the library, which can be used to show any chains of interlocks. If necessary, a new interlock panel can be created by using the visualization tools provided with EDM. This solution, in use for more than 3 years, has proven to be reliable and very flexible.

CERN, Geneva, Switzerland

CERN's Accelerator Controls System is built upon a large set of software services which are vital for daily operations. It is important to instrument these services with sufficient diagnostic and monitoring capabilities to reduce the time to locate a problem and to enable pre-failure detection by surveillance of process internal information. The main challenges here are the diversity of programs (C/C++ and Java) , real-time constraints, the distributed environment and diskless systems. This paper describes which building blocks have been developed to collect process metrics and logs, software deployment and release information and how equipment/software experts today have simple and time-saving access to them using the DIAMON console. This includes the possibility to remotely inspect the process (build-time, version, start time, counters,..) and change its log levels for more detailed information.

Hard real-time systems guarantee by design that no deadline is ever missed. In a distributed environment such as particle accelerators, there is often the extra requirement of having diverse real-time systems synchronize to each other. Implementations on top of general-purpose multi-tasking operating systems such as Linux generally suffer from lack of full control of the platform. On the other hand, solutions based on logic inside FPGAs can result in long development cycles. A mid-way approach is presented which allows fast software development yet guarantees full control of the timing of the execution. The solution involves using soft cores inside FPGAs, running single tasks without interrupts and without an operating system underneath. Two CERN developments are presented, both based on a unique free and open source HDL core comprising a parameterizable number of CPUs, logic to synchronize them and message queues to communicate with the local host and with remote systems. This development environment is being offered as a service to fill the gap between Linux-based solutions and full-hardware implementations.

Message Signalled Interrupts in Mixed-Master Control

operation, FPGA, target, network

1083

GSI, Darmstadt, Germany

Timing Receivers in the FAIR control system are a complex composition of multiple bus-connected components. The bus is composed of Wishbone crossbars which connect master devices to their controlled slaves. These crossbars are in turn connected in master-slave relationships forming a DAG where source nodes are masters, interior nodes are crossbars, and terminal nodes are slaves. In current designs, masters may be found at multiple levels in the composed bus. Bus masters range from embeddedμcontrollers, to DMA controllers, to bridges from PCIe, VME, USB, or the network. In such a system, delivery of interrupts from controlled slaves to masters is non-trivial. The master may reside multiple levels up the hierarchy. In the case of network control, the master may be kilometres of fibre away. Our approach is to use message signalled interrupts (MSI). This is especially important as a particular slave may be controlled by different masters depending on the use-case. MSI allows the routing of interrupts via the same topology used in master-slave control. This paper explores the benefits, disadvantages, and challenges uncovered by our current implementation.

The ALICE Detector Control System has provided its service since 2007. Its operation in the past years proved that the initial design of the system fulfilled all expectations and allowed the evolution of the detectors and operational requirements to follow. In order to minimize the impact of the human factor, many procedures have been optimized and new tools have been introduced in order to allow the operator to supervise about 1 000 000 parameters from a single console. In parallel with the preparation for new runs after the LHC shutdown a prototyping for system extensions which shall be ready in 2018 has started. New detectors will require new approaches to their control and configuration. The conditions data, currently collected after each run, will be provided continuously to a farm containing 100 000 CPU cores and tens of PB of storage. In this paper the DCS design, deployed technologies, and experience gained during the 7 years of operation will be described and the initial assumptions with the current setup will be compared. The current status of the developments for the upgraded system, which will be put into operation in less than 3 years from now, will also be described.

At the synchrotron light source BESSY II monochromator (MONO) and insertion device (ID) scans can be done synchronized in two different modes. In step mode MONO and ID move independently to intermediate target positions of an energy scan. In continuous mode (CM) MONO and ID cover the whole range of the scan nonstop in a coupled motion. Data acquisition is done continuously at the speed provided by the CM scan and is available in regular user operation. Currently CM is in operation at 11 undulator beamlines at BESSY II. 3 new beamlines requesting CM are under construction. During CM the MONO EPICS IOC acts as a controller forcing the MONO optics to follow the movement of the ID. A non-linear predictive control scheme is used to implement this dynamic coupling. The controller task utilizes polynomial regression to extrapolate the ID motion. Calculation of the trajectories for MONO grating and mirror is based on bijective gap to energy lookup tables and the grating equation. In this paper the technical implementation, limitations, recently developed diagnostic methods, and future plans for improvements are presented.

CNL, Ontario, Canada

The Canadian Neutron Beam Centre (CNBC) of the Canadian Nuclear Laboratories (CNL) operate six beam lines for material research. A single beam line experiment requires scientists to acquire data as a sequence of scans that involves data acquisition at many points, varying sample positions, samples, wavelength, sample environment, etc. The points at which measurements must be taken can number in the thousands with scans or their variations having to be run multiple times. At the CNBC an approach has been developed to allow scientists to specify and manage their scans using a set of processes and tools. Scans are specified using a set of constructors and a scan algebra that allows scans to be combined using a set of scan operators. Using the operators of the algebra, complex scan sequences can be constructed from simpler scans and run unattended for up to a few days. Based on the constructors and the algebra, tools are provided to scientists to build, organize and execute their scans. These tools can take the form of scripting languages, spreadsheets, or databases. This scanning technique is currently in use at CNL, and has been implemented in Python on an EPICS based control system.

The 3.8 km circumference Relativistic Heavy Ion Collider (RHIC) at BNL has been in operation since 2000. An electron-ion collider (eRHIC), which is in the design phase, plans to use one of the existing ion rings and new electron rings constructed in the existing tunnel to provide collisions of up to 21.2 GeV electrons with up to 100 GeV gold ions, 250 GeV polarized protons, as well as other species. Many new real-time systems will be required to satisfy the needs of eRHIC, including over 2000 beam position monitors, 1000 beam loss monitors, 18 current monitors, feedback systems, controls for about 10,000 power supplies, machine protection system, new beam timing systems, and more. The selected architecture must be flexible, expandable, cost-effective, reliable, and easy to maintain. Interface with existing and new accelerator timing systems is required, and compatibility with existing infrastructure and equipment must be maintained. Embedded modules based on the Xilinx Zynq gate array, with direct Ethernet connection and on-board Linux, housed in multi-slot chassis (VME, VPX, TCA, etc.) is under consideration. Preliminary design concepts for the architecture will be presented.

Many synchrotron beamlines offer some form of continuous scanning for either energy scanning or sample mapping. However, this is normally done on an ad-hoc beamline by beamline basis. Diamond has recently embarked on an ambitious project to define how to implement continuous scanning as the standard way of doing virtually all mapping tasks on beamlines. The project is split into four main areas: 1) User interfaces to describe the mapping process in a scientifically relevant way, generating a scan description that can be used later; 2) The physical process of scanning and coordinating hardware motion and detector data capture across the beamline; 3) Capture of the detector data and all the associated meta-data to disk. Deciding and describing the layout of the file (or files) for the main use cases; 4) Display and analysis of live data and display of processed data. In order to achieve this common approach across beamlines, the standard software used throughout the facility (Delta Tau motor controllers, EPICS, GDA and DAWN), has been built on.

The increasing complexity of the experimental activity and the growing raw dataset collected during the measurements pushed the integration of the data reduction software within the instrument control. On-line raw data reduction allows users to take instant decisions based on the physical quantities they are looking for. In such a way, beam time is optimised avoiding oversampling. Moreover, the datasets are more consistent and the reduction procedure, becoming now part of the sequencer workflow, is well documented and can be saved for future use. A server and a client API that allows starting and monitoring the reduction procedures on remote machines and finally get their results, was designed. The implementation of the on-line data reduction on several instruments at the ILL as well as on the obtained performances, will be reported in this paper.

Funding: Brazilian Synchrotron Light Laboratory.
As we go to brighter light sources and time resolved ex-periments, different approaches for executing faster scans in synchrotrons are an everpresent need. In many light sources, performing scans through a sequence of hardware triggers is the most commonly used method for synchronizing instruments and motors. Thus, in order to provide a sufficiently flexible and robust solution, the XRay Imaging Beamline (IMX) at the Brazilian Synchrotron Light Source [1] upgraded its scanning system to a NI PXI chassis interfacing with Galil motion controllers and EPICS environment. It currently executes pointtopoint and onthefly scans controlled by hard-ware signals, fully integrated with the beamline control system under EPICS channel access protocol. Some approaches can use CSStudio screens and automated Python scripts to create a userfriendly interface. All pro-gramming languages used in the project are easy to use and to learn, which allows high maintainability for the system delivered. The use of LNLS Hyppie platform [2, 3] also enables software modularity for better compatibil-ity and scalability over different experimental setups and even different beamlines.

The electron/positron injector linac at KEK has injected a variety of beams into the electron accelerator complex of SuperKEKB collider and light sources for particle physics and photon science experiments for more than 30 years. The beam property of electrons and positrons varies in energy from 2.5 GeV to 7 GeV and in bunch charge from 0.2 nC to 10 nC, and their stability requirements are different depending on the injected storage ring. They have to be switched by pulse-to-pulse modulation at 50 Hz. The emittance control is especially crucial to achieve the goal at SuperKEKB and is under development. The beam energy management becomes more important as it affects all of the beam properties. Beam acceleration provided by 60 RF power station should be properly distributed considering redundancy and stability. Thus, the equipment controls are also restructured in order to enable the precise control of the beam properties, based on the synchronized event control system and EPICS control system. The strategy and status of the upgrade is described in this paper from the practical aspects of device controls, online simulation and operation.

The South African MeerKAT radio telescope, currently being built some 90 km outside the small Northern Cape town of Carnarvon, is a precursor to the Square Kilometre Array (SKA) telescope and will be integrated into the mid-frequency component of SKA Phase 1. Providing the graphical user interface (GUI) for MeerKAT required a reassessment of currently employed technologies with a strong focus on leveraging modern user interface technologies and design techniques. An extensive investigation was performed to evaluate and assess potential GUI technologies and frameworks. The result of this investigative study identified a responsive web application for the frontend and asynchronous web server for the backend. In particular the AngularJS framework used in combination with Material Design principles, Websockets and other popular javascript layout and imaging libraries, such as D3.js, proved an ideal fit for the requirements of the MeerKAT GUI frontend. This paper will provide a summary of the user interface technology investigation and further expound on the whole technology stack adopted to provide a modern user interface with real time capabilities.

Creating and supporting Graphical User Interfaces (GUIs) for experiment control and data acquisition has traditionally been a major drain of time and resources for laboratories. GUIs often need to be adapted to new equipment or methods, but typical users lack the technical skills to perform the required modifications, let alone to create new GUIs. Here we present the Taurus* framework which allows a non-programmer to create a fully-featured GUI (with forms, plots, synoptics, etc) from scratch in a few minutes using a "wizard" as well as to customize and expand it by drag-and-dropping elements around at execution time. Moreover, Taurus also gives full control to more advanced users to access, create and customize a GUI programmatically using Python. Taurus is a free, open source, multi-platform pure Python module (it uses PyQt for the GUI). Its support and development are driven by an active and welcoming community participated by several major laboratories and companies which use it for their developments. While Taurus was originally designed within the Sardana** suite for the Tango*** control system, now it can also support other control systems (even simultaneously) via plug-ins.

In this paper, we report the design of the control system for the spallation target in China initiative accelerator driven sub-critical (ADS) system, where a heavy-metal target located vertically at the centre of a sub-critical reactor core is bombarded vertically by the high-energy protons from an accelerator. The main functions of the control system for the target are to monitor and control thermal hydraulic, neutron flux, and accelerator-target interface. The first function is to control the components in the primary and secondary loops, such as pumps, heat exchangers, valves, sensors, etc. For the commissioning measurements of the accelerator, the second function is to monitor the neutrons from the spallation target. The three-layer architecture has been used in the control system. In the middle network layer, in order to increase the network reliability, the redundant Ethernet based on Ethernet ring protection protocol has been considered. In the bottom equipment layer, the equipment controls for the above-mentioned functions have been designed. Finally, because the main objective of the target is to integrate the accelerator and the reactor into one system, the integration of accelerator's control system and the reactor's instrumentation and controls into the target's control system has been mentioned.

Standards-Based Open-Source PLC Diagnostics Monitoring

1151

B. Copy, H. Milcent, M.Z. Zimny
CERN, Geneva, Switzerland

PLCs are widely used to control and monitor industrial processes at CERN. Since these PLCs fulfill critical functions, they must be placed under permanent monitoring. However, due to their proprietary architecture, it is difficult to both monitor the status of these PLCs using vendor-provided software packages and integrate the resulting data with the CERN accelerator infrastructure, which itself relies on CERN-specific protocols. This paper describes the architecture of a stand-alone "PLC diagnostics monitoring" Linux daemon which provides live diagnostics information through standard means and protocols (file logging, CERN protocols, Java Monitoring Extensions). This information is currently consumed by the supervision software which is used by the standby service to monitor the status of critical industrial applications in the LHC and by the monitoring console used by the LHC operators. Both applications are intensively used to monitor and diagnose critical PLC hardware running all over CERN.

CERN, Geneva, Switzerland

The Controls Group of the CERN Beams Department provides more than 400 operator workstations in the CERN Control Centre (CCC) and technical buildings of the accelerators, plus 300 servers in the server room (CCR) of the CCC. During the long shutdown of the accelerators that started in February 2013, many upgrades were done to improve this infrastructure in view of the higher-energy LHC run. The Engineering Department improved the electrical supply with fully redundant UPS, on-site diesel generators and for the CCR, water and air cooling systems. The Information Technology Department increased network bandwidth for the servers by a factor of 10 and introduced a pilot multicast service for the video streaming of the accelerator status displays and beam cameras. The Controls Group removed dependencies on network file systems for the operator accounts they manage for the Linacs, Booster, PS, ISOLDE, AD, CTF3, SPS, LHC and cryogenics. It also moved away from system administration based on shell scripts to using modern tools like version-controlled Ansible playbooks, which are now used for installation, day-to-day re-configuration and staged updates during technical stops.

The Australian Square Kilometre Array Pathfinder (ASKAP) is CSIRO's new radio telescope currently under construction and commissioning at the Murchison Radio-astronomy Observatory (MRO) in the Mid West region of Western Australia. The first six antennas equipped with the first generation (or Mark-I) Phased Array Feeds (PAF) have been in commissioning since 2013. Twelve of the second generation (Mark-II) PAFs are expected to hit the ground late this year leading into the start of the Early Science program. This paper will present the current status of the ASKAP project, including some exciting results coming from the commissioning activities. This will encompass the status of the monitoring and control system, named the Telescope Operating System (TOS), future developments and some of the lessons learned during the early stages of the integration and commissioning phase.

The Laser MegaJoule (LMJ) is a 176-beam laser facility, located at the CEA CESTA Laboratory near Bordeaux (France). It is designed to deliver about 1.4 MJ of energy to targets, for high energy density physics experiments, including fusion experiments. The commissioning of the first bundle of 8 beams was achieved in October 2014. Commissioning of next bundles is on the way. The paper gives an overview of the general control system architecture, which is designed around the industrial SCADA PANORAMA, supervising about 500 000 control points, using 250 virtual machines on the high level and hundreds of PCs and PLCs on the low level. The focus is on the rules and development guidelines that allowed smooth integration for all the subsystems delivered by a dozen of different contractors. The integration platform and simulation tools designed to integrate the hardware and software outside the LMJ facility are also described. Having such tools provides the ability of integrating the command control subsystems regardless the co-activity issues encountered on the facility itself. That was the key point for success.

Recently, the installation of the components for the free electron laser SwissFEL has started at the Paul Scherrer Institute (PSI). In March 2016, beginning of the injector commissioning is planned and first lasing is foreseen a year later. New hardware, like VME64x-boards (IFC 1210, an P2020 based intelligent FPGA controller from IOxOS) and -crates (Trenew), timing system (from MRF with advanced features), motion controllers (Power PMAC from Delta Tau, and MDrive from Schneider), among others, as well as modern field buses, pose great challenges to the controls team. The close interaction of machine- and experiment-components require advanced software concepts for data-acquisition, -distribution, and -archiving. An overview of the project will be presented and the different HW and SW solutions based on the experience gained from preliminary implementations at other facilities of PSI will be explained. First results of the HW commissioning at the SwissFEL will be reported.

ESS has entered the construction phase and the plan is to produce first neutrons by 2019 and to complete the construction by 2025. The Integrated Control System Division (ICS) is responsible to provide control systems for the whole facility. The unprecented beam power of 5 MW and the construction of the facility with many components contributed in-kind presents a number of challenges to the control system. Systems have to be specified so that the work can be effectively shared between the contributors and on-site staff. Control system components need to provide a level of performance that can support the operation of the facility, be standardized so that integration to the facility can be done during a short installation period and be maintainable by the in-house staff after the construction has finished. This paper will outline the plans and principles that will be used to construct the control systems. The selected technologies and standards will be presented, as well as the plans for integration.
