MODPL01	Replacing The Engine In Your Car While You Are Still Driving It - Part II	88
	E. Björklund LANL, Los Alamos, New Mexico, USA
	Two years ago, at the 2015 ICALEPCS conference in Melbourne Australia, we presented a paper entitled 'Replacing The Engine In Your Car While You Are Still Driving It'. In that paper we described the mid-point of a very ambitious, multi-year, upgrade project involving the complete replacement of the low-level RF system, the timing system, the industrial I/O system, the beam-synchronized data acquisition system, the fast-protect reporting system, and much of the diagnostic equipment. That paper focused mostly on the timing system upgrade and presented several observations and recommendations from the perspective of the timing system and its interactions with the other systems. In this paper, now nearly three quarters of the way through our upgrade schedule, we will report on additional observations, challenges, recommendations, and lessons learned from some of the other involved systems.

MODPL02	Virtual Control Commissioning for a Large Critical Ventilation System: The CMS Cavern Use Case	92
	W. Booth, E. Blanco Viñuela, B. Bradu, S. Sourisseau CERN, Geneva, Switzerland
	The current cavern ventilation control system of the CMS experiment at CERN is based on components which are already obsolete: the SCADA system, or close to the end of life: the PLCs. The control system is going to be upgraded during the CERN Long Shutdown 2 (2019-2020) and will be based on the CERN industrial control standard: UNICOS employing WinCC OA as SCADA and Schneider PLCs. Due to the critical nature of the CMS ventilation installation and the short allowed downtime, the approach was to design an environment based on the virtual commissioning of the new control. This solution uses a first principles model of the ventilation system to simulate the real process. The model was developed with the modelling and simulation software EcosimPro. In addition, the current control application of the cavern ventilation will also be re-engineered as it is not completely satisfactory in some transients where many sequences are performed manually and some pressure fluctuations observed could potentially cause issues to the CMS detector. The plant model will also be used to validate new regulation schemes and transient sequences offline in order to ensure a smooth operation in production.

MODPL03	Experience Upgrading Control Systems at the Gemini Telescopes	99
	A.J. Nunez, I. Arriagada, T.D. Gaggstatter, P.E. Gigoux, R. Rojas, M. Westfall Gemini Observatory, Southern Operations Center, La Serena, Chile R. Cardenes, M.J. Rippa Gemini Observatory, Northern Operations Center, Hilo, USA
	The real-time control systems for the Gemini Telescopes were designed and built in the 1990s using state-of-the-art software tools and operating systems of that time. These systems are in use every night, but they have not been kept up-to-date and are now obsolete and also very labor intensive to support. This led Gemini to engage in a major effort to upgrade the software on its telescope control systems. We are in the process of deploying these systems to operations, and in this paper we review the experience and lessons learned through this process and provide an update on future work on other obsolescence management issues.

MODPL04	Framework Upgrade of the Detector Control System for JUNO	107
	Ms. Ye, Z.G. Han IHEP, Bejing, People's Republic of China
	Funding: Jiangmen Underground Neutrino Observatory(JUNO) Experiment The Jiangmen Underground Neutrino Observatory (JUNO) is the second phase of the Daya Bay reactor neutrino experiment. The detector of the experiment was designed as a 20k ton LS with a inner diameter of 34.5 meters casting material acrylic ball shape. Due to the gigantic shape of the detector there are approximate 40k monitoring point including 20k channels of high voltage of array PMT, temperature and humidity, electric crates as well as the power monitoring points. Since most of the DCS of the DayaBay was developed on the framework based on LabVIEW, which is limited by the operation system upgrade and running license, the framework migration and upgrade are needed for DCS of JUNO. The paper will introduce the new framework of DCS based on EPICS (Experimental Physics and Industrial Control System). The implementation of the IOCs of the high-voltage crate and modules, stream device drivers, and the embedded temperature firmware will be presented. The software and hardware realization and the remote control method will be presented. The upgrade framework can be widely used in devices with the same hardware and software interfaces.

MODPL05	Lightweight Acquisition System for Analogue Signals	110
	B.P. Bielawski CERN, Geneva, Switzerland
	In a complex machine such as a particle accelerator there are thousands of analogue signals that need monitoring and even more signals that could be used for debugging or as a tool for detecting symptoms of potentially avoidable problems. Usually it is not feasible to acquire and monitor all of these signals not only because of the cost but also because of cabling and space required. The RF system in the Large Hadron Collider is protected by multiple hardware interlocks that ensure safe operation of klystrons, superconducting cavities and all the other equipment. In parallel, a diagnostic system has been deployed to monitor the health of the klystrons. Due to the limited amount of space and the moderate number of signals to be monitored, a standard approach with a full VME or Compact PCI crate has not been selected. Instead, small embedded industrial computers with USB oscilloscopes chosen for the specific application have been installed. This cost effective, rapidly deployable solution will be presented, including existing and possible future installations as well as the software used to collect the data and integrate it with existing CERN infrastructure.

MODPL06	Recent and Future Upgrades to the Control Systems of LCLS and LCLS-II Scientific Instruments
	D.L. Flath, M.C. Browne, M.L. Gibbs, K. Gumerlock, B.L. Hill, A. Perazzo, M.V. Shankar, T.A. Wallace, D.H. Zhang SLAC, Menlo Park, California, USA
	Funding: LCLS is an Office of Science User Facility operated for the US Department of Energy Office of Science by Stanford University. The Linac Coherent Light Source (LCLS), a US Department of Energy Office of Science user facility, achieved first light in 2009; a total of seven scientific instruments were commissioned through 2015. The EPICS-based control system, in terms of both hardware and software has evolved significantly over eight years of operation as the rate of experiment delivery has increased through means such as photon-beam multiplexing. A description of the upgrades and improvements to hardware, software, tools, and procedures will be presented. Additional discussion points will focus on: (1) the positive effect of upgrades regarding reduction of staffing levels and required skill-level required to support operations; (2) enabling highly skilled staff to focus on further improvements; and (3) current and future upgrades required to support the LCLS-II which will further expand experiment output when it achieves first light in 2020. LCLS-II topics include requirements for automation of routine tasks such as x-ray and optical-laser beam alignment, and focusing as well as improvements to user-interfaces and user-experience which will allow users and non-expert staff to execute experiments.

MODPL07	How Low-Cost Devices Can Help on the Way to ALICE Upgrade	114
	O. Pinazza INFN-Bologna, Bologna, Italy A. Augustinus, P.M. Bond, P.Ch. Chochula, A.N. Kurepin, M. Lechman, J.L. LÃ¥ng, O. Pinazza CERN, Geneva, Switzerland A.N. Kurepin RAS/INR, Moscow, Russia
	The ambitious upgrade plan of the ALICE experiment expects a complete redesign of its data flow after the LHC shutdown scheduled for 2019, for which new electronics modules are being developed in the collaborating institutes. Access to prototypes is at present very limited and full scale prototypes are expected only close to the installation date. To overcome the lack of realistic HW, the ALICE DCS team built small-scale prototypes based on low-cost commercial components (Arduino, Raspberry PI), equipped with environmental sensors, and installed in the experiment areas around and inside the ALICE detector. Communication and control software was developed, based on the architecture proposed for the future detectors, including CERN JCOP FW and ETM WINCC OA. Data provided by the prototypes has been recorded for several months, in presence of beam and magnetic field. The challenge of the harsh environment revealed some insurmountable weaknesses, thus excluding this class of devices from usage in a production setup. They did prove, however, to be robust enough for test purposes, and are still a realistic test-bed for developers while the production of final electronics is continuing.

TUPHA011	A New Distributed Control System for the Consolidation of the CERN Tertiary Infrastructures	390
	L. Scibile, C. Martel, P. Villeton Pachot CERN, Geneva, Switzerland
	The operation of the CERN tertiary infrastructures is carried out via a series of control systems distributed over the CERN sites. The scope comprises: 260 buildings, 2 large heating plants with 27 km heating network and 200 radiators circuits, 500 air handling units, 52 chillers, 300 split systems, 3000 electric boards and 100k light points. With the infrastructure consolidations, CERN is carrying out a migration and an extension of the old control systems dated back to the 70's, 80's and 90's to a new simplified, yet innovative, distributed control system aimed at minimizing the programming and implementation effort, standardizing equipment and methods and reducing lifecycle costs. This new methodology allows for a rapid development and simplified integration of the new controlled infrastructure processes. The basic principle is based on open standards PLC technology that allows to easily interface to a large range of proprietary systems. The local and remote operation and monitoring is carried out seamlessly with Web HMIs that can be accessed via PC, touchpads or mobile devices. This paper reports on the progress and future challenges of this new control system.

TUPHA012	New Control System for LAPECR2	394
	J.J. Chang, S. An, X.J. Liu, P.P. Wang, Y.J. Yuan, W. Zhang IMP/CAS, Lanzhou, People's Republic of China
	Lanzhou All Permanent magnet ECR ion source No.2 (LAPECR2) is the ion source for 320 kV multidiscipline research platform for highly charged ions. Its old control system has been used for nearly 12 years and some prob-lems have been gradually exposed and affected its daily operation. A set of PLC from Beckhoff company is in charge of the control of magnet power supplies, diagnos-tics and motion control. EPICS and Control System Studio (CSS) as well other packages are used in this facility as the control software toolkit. Based on these state-of-the-art technologies on both hardware and software, this paper designed and implemented a new control system for LAPECR2. After about half a year of running, the new control reflects its validity and stability in this facility.

TUPHA013	Accelerator Fault Tracking at CERN	397
	C. Roderick, L. Burdzanowski, D. Martin Anido, S. Pade, P. Wilk CERN, Geneva, Switzerland
	CERNs Accelerator Fault Tracking (AFT) system aims to facilitate answering questions like: "Why are we not doing Physics when we should be?" and "What can we do to increase machine availability?" People have tracked faults for many years, using numerous, diverse, distributed and un-related systems. As a result, and despite a lot of effort, it has been difficult to get a clear and consistent overview of what is going on, where the problems are, how long they last for, and what is the impact. This is particularly true for the LHC, where faults may induce long recovery times after being fixed. The AFT project was launched in February 2014 as collaboration between the Controls and Operations groups with stakeholders from the LHC Availability Working Group (AWG). The AFT system has been used successfully in operation for LHC since 2015, yielding a lot of attention and generating a growing user community. In 2017 the scope has been extended to cover the entire Injector Complex. This paper will describe the AFT system and the way it is used in terms of architecture, features, user communities, workflows and added value for the organisation.

	S. Condamoor, S. Allison, J.J. Sebek, J.A. Vásquez, J.V. Wachter SLAC, Menlo Park, California, USA
	Funding: Work is supported by the U.S. Department of Energy, Office of Science under Contract DE-AC02-76SF00515 SLAC's SPEAR3 Booster RF system was recently upgraded where the existing klystron providing RF power to a 5-cell cavity was replaced with a Solid State Amplifier (SSA). The Low Level RF Controls (LLRF) to drive the SSA was provided by a high performance FPGA based system built on SLAC ATCA modules. RF Cavity Tuner Controls were replaced with EtherCAT-based stepper motor controller. New hardware was designed and built for PLC-based Machine Protection System (MPS). Fast digitizers to sample and acquire LLRF signals were implemented in a LinuxRT Server. All of these required new Controls Software implementation. This poster illustrates the Controls associated with each of the above hardware.

TUPHA016	Overview of the GANIL Control Systems for the Different Projects Around the Facility	406
	E. Lécorché, D.J.C. Deroy, P. Gillette, C.H. Haquin, E. Lemaître, C.H. Patard, L. Philippe, R.J.F. Roze, D.T. Touchard GANIL, Caen, France
	The GANIL facility is drastically extending its possibilities with new projects, so increasing its capabilities in nuclear physics. The most significant one is the Spiral2 installation based on a linear accelerator, then to be associated with the S3, NFS and DESIR new experimental rooms. Beside of the legacy home made control system handling the original installation, Epics was chosen as the basic framework for these projects. First, some control system components were used during preliminary beam tests. In parallel, the whole architecture was designed while the organization for future operation started to be considered; also, more structured and sophisticated tools were developed and the first high level applications for the whole machine tuning started to be tested, jointly with the current onsite beam commissioning. Progression of the control system development is presented, from the first beam tests up to the whole Spiral2 commissioning. Then, according to the new projects to cope with, some highlights are given concerning the related organization as well as specific items and developments to be considered, taking benefit from the Spiral2 control system feedback experience.

TUPHA019	Optimized Calculation of Timing for Parallel Beam Operation at the FAIR Accelerator Complex	411
	A. Schaller, J. Fitzek GSI, Darmstadt, Germany D. Lorenz, F. Wolf TU Darmstadt, Darmstadt, Germany
	For the new FAIR accelerator complex at GSI the settings management system LSA is used. It is developed in collaboration with CERN and until now it is executed strictly serial. Nowadays the performance gain of single core processors have nearly stagnated and multicore processors dominate the market. This evolution forces software projects to make use of the parallel hardware to increase their performance. In this thesis LSA is analyzed and parallelized using different parallelization patterns like task and loop parallelization. The most common case of user interaction is to change specific settings so that the accelerator performs at its best. For each changed setting, LSA needs to calculate all child settings of the parameter hierarchy. To maximize the speedup of the calculations, they are also optimized sequentially. The used data structures and algorithms are reviewed to ensure minimal resource usage and maximal compatibility with parallel execution. The overall goal of this thesis is to speed up the calculations so that the results can be shown in a user interface with nearly no noticeable latency.

TUPHA020	MATLAB Control Applications Embedded Into Epics Process Controllers (IOC) and their Impact on Facility Operations at Paul Scherrer Institute	416
	P. Chevtsov, T. Pal PSI, Villigen PSI, Switzerland M. Dach Dach Consulting GmbH, Brugg, Switzerland
	An automated tool for converting MATLAB based controls algorithms into C codes, executable directly on EPICS process control computers (IOCs), was developed at the Paul Scherrer Institute (PSI). Based on this tool, several high level control applications were embedded into the IOCs, which are directly connected to the control system sensors and actuators. Such embedded applications have significantly reduced the network traffic, and thus the data handling latency, which increased the reliability of the control system. The paper concentrates on the most important components of the automated tool and the performance of MATLAB algorithms converted by this tool.

TUPHA021	Experiences Using Linux Based VME Controller Boards	420
	D. Zimoch, D. Anicic PSI, Villigen PSI, Switzerland
	For many years, we have used a commercial real-time operating system to run EPICS on VME controller boards. However, with the availability of EPICS on Linux it became more and more charming to use Linux not only for PCs, but for VME controller boards as well. With a true multi-process environment, open source software and all standard Linux tools available, development and debugging promised to become much easier. Also the cost factor looked attractive, given that Linux is for free. However, we had to learn that there is no such thing as a free lunch. While developing EPICS support for the VME bus interface was quite straight forward, pitfalls waited at unexpected places. We present challenges and solutions encountered while making Linux based real-time VME controllers the main control system component in SwissFEL.

TUPHA024	ModBus/TCP Applications for CEBAF Accelerator Control System	424
	J. Yan, S. Philip, C. Seaton JLab, Newport News, Virginia, USA
	Modbus-TCP is the Modbus RTU protocol with the TCP interface running on Ethernet. In our applications, an XPort device utilizing Modbus-TCP is used to control remote devices and communicates with the accelerator control system (EPICS). Modbus software provides a layer between the standard EPICS asyn support and EPICS asyn for TCP/IP or serial port driver. The EPICS application for each specific Modbus device is developed and it can be deployed on a soft IOC. The configuration of XPort and Modbus-TCP is easy to setup and suitable for applications that do not require high-speed communications. Additionally, the use of Ethernet makes it quicker to develop instrumentation for remote deployment. An eight-channel 24-bit Data Acquisition (DAQ) system is used to test the hardware and software capabilities.

TUPHA028	Recent Update of the RIKEN RI Beam Factory Control System	427
	M. Komiyama, M. Fujimaki, N. Fukunishi, A. Uchiyama RIKEN Nishina Center, Wako, Japan M. Hamanaka, T. Nakamura SHI Accelerator Service Ltd., Tokyo, Japan
	RIKEN Radioactive Isotope Beam Factory (RIBF) is a cyclotron-based heavy-ion accelerator facility for producing unstable nuclei and studying their properties. Many components of the RIBF accelerator complex are controlled by using the Experimental Physics and Industrial Control System (EPICS). We will here present the overview of the EPICS-based RIBF control system and its latest update work in progress. We are developing a new beam interlock system from scratch for applying to some of the small experimental facility in the RIBF accelerator complex. The new beam interlock system is based on a programmable logic controller (PLC) as well as the existing beam interlock system of RIBF (BIS), however, we newly employ a Linux-based PLC-CPU on which EPICS programs can be executed in addition to a sequencer in order to speed up the system. After optimize the performance of the system while continuing operation, we plan to expand the new system as a successor to the BIS that has been working more than 10 years since the start of its operation.

TUPHA032	Parallel Processing for the High Frame Rate Upgrade of the LHC Synchrotron Radiation Telescope	442
	D. Alves, E. Bravin, G. Trad CERN, Geneva, Switzerland
	The Beam Synchrotron Radiation Telescope (BSRT) is routinely used for estimating the transverse beam size, pro'le and emittance in the LHC; quantities playing a crucial role in the optimisation of the luminosity levels required by the experiments. During the 2017 LHC run, the intensi'ed analog cameras used by this system to image the beam have been replaced by GigE digital cameras coupled to image intensi'ers. Preliminary tests revealed that the typically used sub-image rectangles of 128×128 pixels can be acquired at rates of up to 400 frames per second, more than 10 times faster than the previous acquisition rate. To address the increase in CPU workload for the image processing, new VME CPU cards (Intel 4 core/2.5GHz/8GB RAM) are envisaged to be installed (replacing the previous Intel Core 2 Duo/1.5GHz/1GB RAM). This paper focuses on the software changes proposed in order to take advantage of the multi-core capabilities of the new CPU for parallel computations. It will describe how beam profile calculations can be pipe-lined through a thread pool while ensuring that the CPU keeps up with the increased data rate. To conclude, an analysis of the system performance will be presented.

THMPA09	MACUP (Material for data ACquisition - UPgrade): Project Focusing on DAQ Hardware Architecture Upgrades for SOLEIL	1330
	G. Renaud, Y.-M. Abiven, F. Ta, Q.H. Tran, S. Zhang SOLEIL, Gif-sur-Yvette, France
	Since operation-startup more than 10 years ago, Synchrotron SOLEIL has chosen acquisition architectures that are mainly based on CompactPCI systems. The last few years there has however been an acceleration of obsolescence issues on the CPCI products and it has also been identified that this technology would become a bottleneck in terms of performance for new projects. The MACUP project was therefore created with two main objectives: maintaining the current facility operations by addressing the hardware obsolescence risks, all while searching for alternate high-performance solutions with better embedded processing capabilities to face new challenging requirements. One additional guideline for the project is to facilitate collaborative work for accelerator and beamline projects by evaluating and standardizing a limited set of technologies like the Xilinx ZYNQ SOC, VITA 57 FMC and μTCA standards. This paper describes the adopted methodologies and roadmap to drive this project.

THPHA012	Upgrade of Vacuum Control System for Komac Linac and Beamlines	1358

	Funding: This work was supported by the Ministry of Science, ICT & Future Planning of the Korean Government At Korea Multi-purpose Accelerator Complex (KO-MAC), we have been operating a proton linac since 2013 [1]. It consists of a 100 MeV accelerator and 5 operational target rooms. Beam operation at KOMAC is carried out by a home-grown control system with a machine protection system which affects the accelerator the least when the machine suddenly fails. Our work is mainly concentrated on interlock sequence of vacuum related equipments based on a programmable logic controller (PCL). PCLs monitor vacuum status and control vacuum pumps and gate valves. By applying interlock sequence to PCLs connected to the vacuum equipments, we close gate valves to isolate a failed part so the the rest of the accelerator remains under vacuum, and safely shut down the vacuum pumps. Then the MPS receives a signal to safely stop the beam operation to protect the accelerator. We describe in this paper architecture of our PLC on interlock sequence of vacuum related equipment and its implementation. "vacuum", "Interlock"

THPHA013	Control System Projects at the Electron Storage Ring DELTA	1361
	D. Schirmer, A. Althaus, P. Hartmann, D. Rohde DELTA, Dortmund, Germany
	Data logging and archiving is an important task to identify and investigate malfunctions during storage ring operation. In order to enable a high-performance fault analysis, large amounts of data must be processed effectively. For this purpose a fundamental redesign of the present SQL database was necessary. The VME/VxWorks-driven CAN bus has been used for many years as the main field bus of the DELTA control system. Unfortunately, the corresponding CAN bus I/O modules were discontinued by the manufacturer. Thus, the CAN field bus is currently being replaced by a more up to date Modbus/TCP-IP communication (WAGO), which largely supersedes the VME/VxWorks layer. After hard- and software integration into the EPICS environment, several projects have been realized using this powerful field bus communication. The server migration to a 64-bit architecture was already carried out in the past. By now, all client programs and software tools have also been converted to 64-bit versions. In addition, the fast orbit feedback system project, using an in-house developed FPGA-based hardware, has been resumed.

THPHA014	Evolution in the Development of the Italian Single-dish COntrol System (DISCOS)	1366
	A. Orlati, M. Bartolini, S. Righini INAF - IRA, Bologna, Italy M. Buttu, A. Fara, C. Migoni, S. Poppi INAF - OAC, Selargius (CA), Italy
	DISCOS [] is a control system developed by the Italian National Institute for Astrophysics (INAF) and currently in use at three radio telescope facilities of Medicina, Noto and the Sardinia Radio Telescope (SRT) []. DISCOS development is based on the adoption of the ALMA Common Software (ACS) framework. During the last two years, besides assisting the astronomical commissioning of the newly-built SRT and enabling its early science program, the control system has undergone some major upgrades. The long-awaited transition to a recent ACS version was performed, migrating the whole code base to 64 bit operative system and compilers, addressing the obsolescence problem that was causing a major technical debt to the project. This opportunity allowed us to perform some refactoring, in order to implement improved logging and resource management. During this transition the code management platform was migrated to a git-based versioning system and the continuous integration platform was modified to accommodate these changes. Further upgrades included the system completion at Noto and the expansion to handle new digital backends. Orlati A. et al.

	The vacuum control of the Large Hadron Collider and its injectors is based on PLC and SCADA off-the-shelf components. Since late '90s, CERN's vacuum group has developed a dedicated control framework to drive, monitor and log the more than 10 000 vacuum instruments. Also, in 1998, CERN's industrial controls group developed the UNICOS framework (UNified Industrial Control System), becoming a de facto standard of industrial control systems and gradually deployed in different domains at CERN (e.g. Cryogenics, HVAC…). After an initial prototype applying the UNICOS-CPC (Continuous Process Control) framework to the controls of some vacuum installations, both teams have been working on the development of vacuum-specific objects and their integration, together with new features, into the UNICOS framework. Such convergence will allow this generic framework to better fit the vacuum systems, while offering the advantages of using a widespread and well-supported framework. This paper reports on the experience acquired in the development and deployment of vacuum specific objects in running installations, as a prototype for the vacuum controls convergence with UNICOS.

	Funding: Department of Energy contract DE-AC02-76SF00515. At the heart of the LCLS-II are two undulator lines: the hard x-ray (HXR) line and the soft x-ray line (SXR). The SXR line is comprised of 21 variable gap undulator segments separated by an interspace stands with a cam positioning system capable of positioning in 5 degrees of freedom (DOF). The undulator segment motion control utilizes the Aerotech Ensemble motion controller through an EPICS Soft IOC (input-output controller). Its drive system consists of a Harmonic Drive servo system with feedback from two absolute full-gap encoders. Additional Aerotech motion controllers are used to control the cam-positioning system and phase shifters of the interspace stand. The HXR line is comprised of 32 undulator segments each including an integrated interspace assembly. The segment girder is placed on two stands with a similar cam-positioning system as in the SXR line allowing for movement in 5 DOF. As one of the design goals of the HXR line was to reuse the original LCLS girder positioning system, the motion control system is an upgraded version of that original system, using RTEMS on VME with Animatics SmartMotors.

	The paper describes planning and execution of large-scale maintenance campaigns of SCADA systems for CERN accelerator and technical infrastructure. These activities, required to keep up with the pace of development of the controlled systems and rapid evolution of software, are constrained by many factors, such as availability for operation and planned interventions on equipment. Experience gathered throughout the past ten years of maintenance campaigns for the SCADA Applications Service at CERN, covering over 230 systems distributed across almost 120 servers, is presented. Further improvements for the procedures and tools are proposed to adapt to the increasing number of applications in the service and reduce maintenance effort and required downtime.

	With the advent of LCLS-II, SLAC must effectively and collectively plan for operation of its premiere scientific production facility. LCLS-II presents unique new challenges for SLAC, with its electron beam rate of up to 1MHz, complex bunch patterns, and multiple beam destinations. These machine advancements, along with long-term goals for automated tuning, model dependent and independent analysis, and machine learning provide strong motivation to enhance the SLAC software toolkit based on augmenting EPICS V3 to take full advantage of EPICS V4 - which supports structured data and facilitates a language-agnostic middle-ware service layer. The software platform upgrade path in support of controls, online physics and experimental facilities software for the LCLS-I/II complex is described.

	Funding: SLAC National Accelerator Lab The Klystron Bake Station at SLAC is a facility for baking out klystrons (high power RF amplifiers) among other equipment in preparation for installation in the linac. The scope of this project was to upgrade the 30 year old controls (based on VMS and CAMAC) to utilize PLC automation and an EPICS user interface. The new system allows for flexible configuration of the bake out schedule which can be saved to files or edited real time both through an EPICS soft IOC as well as a local touch panel HMI. Other improvements include active long term archiving of all data, COTS hardware (replacing custom-built CAMAC cards), email notification of fault states, and graphical user interfaces (old system was command line only). The first station upgraded came online in November 2016 and two more stations are planned to follow this year. Year poster discusses the improvements made and problems encountered in performing the upgrade.

	Funding: HIT Betriebs GmbH Changes in the accelerator beamline of the Heidelberg Ionbeam Therapy-Center necessitated a relevant change in the accelerator control system. Specifically the addition of a third ion source to the LEBT beamline dictated an expansion of the Virtual Accelerator structure both in the database and the DCU software. The decision to go to a virtual server infrastructure to meet the demands for better redundancy and performance prompted an overhaul of the ACS software and hardware base. Two new redundant virtualization servers and doubled storage systems helped to increase safety and system performance. To take advantage of the newer hardware and 64-bit operating systems, all software was converted to a 64 bit base. Additionally, as a quality of life and security improvement, the download and flash functionality of the ACS were updated to enhance performance and security checks for quality assurance measures. The new virtualization host server and infrastructure hardware in conjunction with the 64 bit update and ensuing efficiency increases have resulted in a safer and significantly faster ACS with higher redundancy in case of hardware failure.

Replacing The Engine In Your Car While You Are Still Driving It - Part II

88

E. Björklund
LANL, Los Alamos, New Mexico, USA

Two years ago, at the 2015 ICALEPCS conference in Melbourne Australia, we presented a paper entitled 'Replacing The Engine In Your Car While You Are Still Driving It*'. In that paper we described the mid-point of a very ambitious, multi-year, upgrade project involving the complete replacement of the low-level RF system, the timing system, the industrial I/O system, the beam-synchronized data acquisition system, the fast-protect reporting system, and much of the diagnostic equipment. That paper focused mostly on the timing system upgrade and presented several observations and recommendations from the perspective of the timing system and its interactions with the other systems. In this paper, now nearly three quarters of the way through our upgrade schedule, we will report on additional observations, challenges, recommendations, and lessons learned from some of the other involved systems.

Virtual Control Commissioning for a Large Critical Ventilation System: The CMS Cavern Use Case

92

W. Booth, E. Blanco Viñuela, B. Bradu, S. Sourisseau
CERN, Geneva, Switzerland

The current cavern ventilation control system of the CMS experiment at CERN is based on components which are already obsolete: the SCADA system, or close to the end of life: the PLCs. The control system is going to be upgraded during the CERN Long Shutdown 2 (2019-2020) and will be based on the CERN industrial control standard: UNICOS employing WinCC OA as SCADA and Schneider PLCs. Due to the critical nature of the CMS ventilation installation and the short allowed downtime, the approach was to design an environment based on the virtual commissioning of the new control. This solution uses a first principles model of the ventilation system to simulate the real process. The model was developed with the modelling and simulation software EcosimPro. In addition, the current control application of the cavern ventilation will also be re-engineered as it is not completely satisfactory in some transients where many sequences are performed manually and some pressure fluctuations observed could potentially cause issues to the CMS detector. The plant model will also be used to validate new regulation schemes and transient sequences offline in order to ensure a smooth operation in production.

The real-time control systems for the Gemini Telescopes were designed and built in the 1990s using state-of-the-art software tools and operating systems of that time. These systems are in use every night, but they have not been kept up-to-date and are now obsolete and also very labor intensive to support. This led Gemini to engage in a major effort to upgrade the software on its telescope control systems. We are in the process of deploying these systems to operations, and in this paper we review the experience and lessons learned through this process and provide an update on future work on other obsolescence management issues.

Framework Upgrade of the Detector Control System for JUNO

107

Ms. Ye, Z.G. Han
IHEP, Bejing, People's Republic of China

Funding: Jiangmen Underground Neutrino Observatory(JUNO) Experiment
The Jiangmen Underground Neutrino Observatory (JUNO) is the second phase of the Daya Bay reactor neutrino experiment. The detector of the experiment was designed as a 20k ton LS with a inner diameter of 34.5 meters casting material acrylic ball shape. Due to the gigantic shape of the detector there are approximate 40k monitoring point including 20k channels of high voltage of array PMT, temperature and humidity, electric crates as well as the power monitoring points. Since most of the DCS of the DayaBay was developed on the framework based on LabVIEW, which is limited by the operation system upgrade and running license, the framework migration and upgrade are needed for DCS of JUNO. The paper will introduce the new framework of DCS based on EPICS (Experimental Physics and Industrial Control System). The implementation of the IOCs of the high-voltage crate and modules, stream device drivers, and the embedded temperature firmware will be presented. The software and hardware realization and the remote control method will be presented. The upgrade framework can be widely used in devices with the same hardware and software interfaces.

Lightweight Acquisition System for Analogue Signals

110

B.P. Bielawski
CERN, Geneva, Switzerland

In a complex machine such as a particle accelerator there are thousands of analogue signals that need monitoring and even more signals that could be used for debugging or as a tool for detecting symptoms of potentially avoidable problems. Usually it is not feasible to acquire and monitor all of these signals not only because of the cost but also because of cabling and space required. The RF system in the Large Hadron Collider is protected by multiple hardware interlocks that ensure safe operation of klystrons, superconducting cavities and all the other equipment. In parallel, a diagnostic system has been deployed to monitor the health of the klystrons. Due to the limited amount of space and the moderate number of signals to be monitored, a standard approach with a full VME or Compact PCI crate has not been selected. Instead, small embedded industrial computers with USB oscilloscopes chosen for the specific application have been installed. This cost effective, rapidly deployable solution will be presented, including existing and possible future installations as well as the software used to collect the data and integrate it with existing CERN infrastructure.

Funding: LCLS is an Office of Science User Facility operated for the US Department of Energy Office of Science by Stanford University.
The Linac Coherent Light Source (LCLS), a US Department of Energy Office of Science user facility, achieved first light in 2009; a total of seven scientific instruments were commissioned through 2015. The EPICS-based control system, in terms of both hardware and software has evolved significantly over eight years of operation as the rate of experiment delivery has increased through means such as photon-beam multiplexing. A description of the upgrades and improvements to hardware, software, tools, and procedures will be presented. Additional discussion points will focus on: (1) the positive effect of upgrades regarding reduction of staffing levels and required skill-level required to support operations; (2) enabling highly skilled staff to focus on further improvements; and (3) current and future upgrades required to support the LCLS-II which will further expand experiment output when it achieves first light in 2020. LCLS-II topics include requirements for automation of routine tasks such as x-ray and optical-laser beam alignment, and focusing as well as improvements to user-interfaces and user-experience which will allow users and non-expert staff to execute experiments.

The ambitious upgrade plan of the ALICE experiment expects a complete redesign of its data flow after the LHC shutdown scheduled for 2019, for which new electronics modules are being developed in the collaborating institutes. Access to prototypes is at present very limited and full scale prototypes are expected only close to the installation date. To overcome the lack of realistic HW, the ALICE DCS team built small-scale prototypes based on low-cost commercial components (Arduino, Raspberry PI), equipped with environmental sensors, and installed in the experiment areas around and inside the ALICE detector. Communication and control software was developed, based on the architecture proposed for the future detectors, including CERN JCOP FW and ETM WINCC OA. Data provided by the prototypes has been recorded for several months, in presence of beam and magnetic field. The challenge of the harsh environment revealed some insurmountable weaknesses, thus excluding this class of devices from usage in a production setup. They did prove, however, to be robust enough for test purposes, and are still a realistic test-bed for developers while the production of final electronics is continuing.

A New Distributed Control System for the Consolidation of the CERN Tertiary Infrastructures

390

L. Scibile, C. Martel, P. Villeton Pachot
CERN, Geneva, Switzerland

The operation of the CERN tertiary infrastructures is carried out via a series of control systems distributed over the CERN sites. The scope comprises: 260 buildings, 2 large heating plants with 27 km heating network and 200 radiators circuits, 500 air handling units, 52 chillers, 300 split systems, 3000 electric boards and 100k light points. With the infrastructure consolidations, CERN is carrying out a migration and an extension of the old control systems dated back to the 70's, 80's and 90's to a new simplified, yet innovative, distributed control system aimed at minimizing the programming and implementation effort, standardizing equipment and methods and reducing lifecycle costs. This new methodology allows for a rapid development and simplified integration of the new controlled infrastructure processes. The basic principle is based on open standards PLC technology that allows to easily interface to a large range of proprietary systems. The local and remote operation and monitoring is carried out seamlessly with Web HMIs that can be accessed via PC, touchpads or mobile devices. This paper reports on the progress and future challenges of this new control system.

Lanzhou All Permanent magnet ECR ion source No.2 (LAPECR2) is the ion source for 320 kV multidiscipline research platform for highly charged ions. Its old control system has been used for nearly 12 years and some prob-lems have been gradually exposed and affected its daily operation. A set of PLC from Beckhoff company is in charge of the control of magnet power supplies, diagnos-tics and motion control. EPICS and Control System Studio (CSS) as well other packages are used in this facility as the control software toolkit. Based on these state-of-the-art technologies on both hardware and software, this paper designed and implemented a new control system for LAPECR2. After about half a year of running, the new control reflects its validity and stability in this facility.

Accelerator Fault Tracking at CERN

397

C. Roderick, L. Burdzanowski, D. Martin Anido, S. Pade, P. Wilk
CERN, Geneva, Switzerland

CERNs Accelerator Fault Tracking (AFT) system aims to facilitate answering questions like: "Why are we not doing Physics when we should be?" and "What can we do to increase machine availability?" People have tracked faults for many years, using numerous, diverse, distributed and un-related systems. As a result, and despite a lot of effort, it has been difficult to get a clear and consistent overview of what is going on, where the problems are, how long they last for, and what is the impact. This is particularly true for the LHC, where faults may induce long recovery times after being fixed. The AFT project was launched in February 2014 as collaboration between the Controls and Operations groups with stakeholders from the LHC Availability Working Group (AWG). The AFT system has been used successfully in operation for LHC since 2015, yielding a lot of attention and generating a growing user community. In 2017 the scope has been extended to cover the entire Injector Complex. This paper will describe the AFT system and the way it is used in terms of architecture, features, user communities, workflows and added value for the organisation.

SLAC's SPEAR3 Booster RF system was recently upgraded where the existing klystron providing RF power to a 5-cell cavity was replaced with a Solid State Amplifier (SSA). The Low Level RF Controls (LLRF) to drive the SSA was provided by a high performance FPGA based system built on SLAC ATCA modules. RF Cavity Tuner Controls were replaced with EtherCAT-based stepper motor controller. New hardware was designed and built for PLC-based Machine Protection System (MPS). Fast digitizers to sample and acquire LLRF signals were implemented in a LinuxRT Server. All of these required new Controls Software implementation. This poster illustrates the Controls associated with each of the above hardware.

The GANIL facility is drastically extending its possibilities with new projects, so increasing its capabilities in nuclear physics. The most significant one is the Spiral2 installation based on a linear accelerator, then to be associated with the S3, NFS and DESIR new experimental rooms. Beside of the legacy home made control system handling the original installation, Epics was chosen as the basic framework for these projects. First, some control system components were used during preliminary beam tests. In parallel, the whole architecture was designed while the organization for future operation started to be considered; also, more structured and sophisticated tools were developed and the first high level applications for the whole machine tuning started to be tested, jointly with the current onsite beam commissioning. Progression of the control system development is presented, from the first beam tests up to the whole Spiral2 commissioning. Then, according to the new projects to cope with, some highlights are given concerning the related organization as well as specific items and developments to be considered, taking benefit from the Spiral2 control system feedback experience.

411

GSI, Darmstadt, Germany

TU Darmstadt, Darmstadt, Germany

For the new FAIR accelerator complex at GSI the settings management system LSA is used. It is developed in collaboration with CERN and until now it is executed strictly serial. Nowadays the performance gain of single core processors have nearly stagnated and multicore processors dominate the market. This evolution forces software projects to make use of the parallel hardware to increase their performance. In this thesis LSA is analyzed and parallelized using different parallelization patterns like task and loop parallelization. The most common case of user interaction is to change specific settings so that the accelerator performs at its best. For each changed setting, LSA needs to calculate all child settings of the parameter hierarchy. To maximize the speedup of the calculations, they are also optimized sequentially. The used data structures and algorithms are reviewed to ensure minimal resource usage and maximal compatibility with parallel execution. The overall goal of this thesis is to speed up the calculations so that the results can be shown in a user interface with nearly no noticeable latency.

An automated tool for converting MATLAB based controls algorithms into C codes, executable directly on EPICS process control computers (IOCs), was developed at the Paul Scherrer Institute (PSI). Based on this tool, several high level control applications were embedded into the IOCs, which are directly connected to the control system sensors and actuators. Such embedded applications have significantly reduced the network traffic, and thus the data handling latency, which increased the reliability of the control system. The paper concentrates on the most important components of the automated tool and the performance of MATLAB algorithms converted by this tool.

For many years, we have used a commercial real-time operating system to run EPICS on VME controller boards. However, with the availability of EPICS on Linux it became more and more charming to use Linux not only for PCs, but for VME controller boards as well. With a true multi-process environment, open source software and all standard Linux tools available, development and debugging promised to become much easier. Also the cost factor looked attractive, given that Linux is for free. However, we had to learn that there is no such thing as a free lunch. While developing EPICS support for the VME bus interface was quite straight forward, pitfalls waited at unexpected places. We present challenges and solutions encountered while making Linux based real-time VME controllers the main control system component in SwissFEL.

ModBus/TCP Applications for CEBAF Accelerator Control System

424

J. Yan, S. Philip, C. Seaton
JLab, Newport News, Virginia, USA

Modbus-TCP is the Modbus RTU protocol with the TCP interface running on Ethernet. In our applications, an XPort device utilizing Modbus-TCP is used to control remote devices and communicates with the accelerator control system (EPICS). Modbus software provides a layer between the standard EPICS asyn support and EPICS asyn for TCP/IP or serial port driver. The EPICS application for each specific Modbus device is developed and it can be deployed on a soft IOC. The configuration of XPort and Modbus-TCP is easy to setup and suitable for applications that do not require high-speed communications. Additionally, the use of Ethernet makes it quicker to develop instrumentation for remote deployment. An eight-channel 24-bit Data Acquisition (DAQ) system is used to test the hardware and software capabilities.

RIKEN Radioactive Isotope Beam Factory (RIBF) is a cyclotron-based heavy-ion accelerator facility for producing unstable nuclei and studying their properties. Many components of the RIBF accelerator complex are controlled by using the Experimental Physics and Industrial Control System (EPICS). We will here present the overview of the EPICS-based RIBF control system and its latest update work in progress. We are developing a new beam interlock system from scratch for applying to some of the small experimental facility in the RIBF accelerator complex. The new beam interlock system is based on a programmable logic controller (PLC) as well as the existing beam interlock system of RIBF (BIS), however, we newly employ a Linux-based PLC-CPU on which EPICS programs can be executed in addition to a sequencer in order to speed up the system. After optimize the performance of the system while continuing operation, we plan to expand the new system as a successor to the BIS that has been working more than 10 years since the start of its operation.

Parallel Processing for the High Frame Rate Upgrade of the LHC Synchrotron Radiation Telescope

442

D. Alves, E. Bravin, G. Trad
CERN, Geneva, Switzerland

The Beam Synchrotron Radiation Telescope (BSRT) is routinely used for estimating the transverse beam size, pro'le and emittance in the LHC; quantities playing a crucial role in the optimisation of the luminosity levels required by the experiments. During the 2017 LHC run, the intensi'ed analog cameras used by this system to image the beam have been replaced by GigE digital cameras coupled to image intensi'ers. Preliminary tests revealed that the typically used sub-image rectangles of 128×128 pixels can be acquired at rates of up to 400 frames per second, more than 10 times faster than the previous acquisition rate. To address the increase in CPU workload for the image processing, new VME CPU cards (Intel 4 core/2.5GHz/8GB RAM) are envisaged to be installed (replacing the previous Intel Core 2 Duo/1.5GHz/1GB RAM). This paper focuses on the software changes proposed in order to take advantage of the multi-core capabilities of the new CPU for parallel computations. It will describe how beam profile calculations can be pipe-lined through a thread pool while ensuring that the CPU keeps up with the increased data rate. To conclude, an analysis of the system performance will be presented.

MACUP (Material for data ACquisition - UPgrade): Project Focusing on DAQ Hardware Architecture Upgrades for SOLEIL

1330

SOLEIL, Gif-sur-Yvette, France

Since operation-startup more than 10 years ago, Synchrotron SOLEIL has chosen acquisition architectures that are mainly based on CompactPCI systems. The last few years there has however been an acceleration of obsolescence issues on the CPCI products and it has also been identified that this technology would become a bottleneck in terms of performance for new projects. The MACUP project was therefore created with two main objectives: maintaining the current facility operations by addressing the hardware obsolescence risks, all while searching for alternate high-performance solutions with better embedded processing capabilities to face new challenging requirements. One additional guideline for the project is to facilitate collaborative work for accelerator and beamline projects by evaluating and standardizing a limited set of technologies like the Xilinx ZYNQ SOC, VITA 57 FMC and μTCA standards. This paper describes the adopted methodologies and roadmap to drive this project.

At Korea Multi-purpose Accelerator Complex (KO-MAC), we have been operating a proton linac since 2013 [1]. It consists of a 100 MeV accelerator and 5 operational target rooms. Beam operation at KOMAC is carried out by a home-grown control system with a machine protection system which affects the accelerator the least when the machine suddenly fails. Our work is mainly concentrated on interlock sequence of vacuum related equipments based on a programmable logic controller (PCL). PCLs monitor vacuum status and control vacuum pumps and gate valves. By applying interlock sequence to PCLs connected to the vacuum equipments, we close gate valves to isolate a failed part so the the rest of the accelerator remains under vacuum, and safely shut down the vacuum pumps. Then the MPS receives a signal to safely stop the beam operation to protect the accelerator. We describe in this paper architecture of our PLC on interlock sequence of vacuum related equipment and its implementation.

Control System Projects at the Electron Storage Ring DELTA

1361

DELTA, Dortmund, Germany

Data logging and archiving is an important task to identify and investigate malfunctions during storage ring operation. In order to enable a high-performance fault analysis, large amounts of data must be processed effectively. For this purpose a fundamental redesign of the present SQL database was necessary. The VME/VxWorks-driven CAN bus has been used for many years as the main field bus of the DELTA control system. Unfortunately, the corresponding CAN bus I/O modules were discontinued by the manufacturer. Thus, the CAN field bus is currently being replaced by a more up to date Modbus/TCP-IP communication (WAGO), which largely supersedes the VME/VxWorks layer. After hard- and software integration into the EPICS environment, several projects have been realized using this powerful field bus communication. The server migration to a 64-bit architecture was already carried out in the past. By now, all client programs and software tools have also been converted to 64-bit versions. In addition, the fast orbit feedback system project, using an in-house developed FPGA-based hardware, has been resumed. This report provides an overview of the developments and results of each project.

DISCOS [*] is a control system developed by the Italian National Institute for Astrophysics (INAF) and currently in use at three radio telescope facilities of Medicina, Noto and the Sardinia Radio Telescope (SRT) [**]. DISCOS development is based on the adoption of the ALMA Common Software (ACS) framework. During the last two years, besides assisting the astronomical commissioning of the newly-built SRT and enabling its early science program, the control system has undergone some major upgrades. The long-awaited transition to a recent ACS version was performed, migrating the whole code base to 64 bit operative system and compilers, addressing the obsolescence problem that was causing a major technical debt to the project. This opportunity allowed us to perform some refactoring, in order to implement improved logging and resource management. During this transition the code management platform was migrated to a git-based versioning system and the continuous integration platform was modified to accommodate these changes. Further upgrades included the system completion at Noto and the expansion to handle new digital backends.

The vacuum control of the Large Hadron Collider and its injectors is based on PLC and SCADA off-the-shelf components. Since late '90s, CERN's vacuum group has developed a dedicated control framework to drive, monitor and log the more than 10 000 vacuum instruments. Also, in 1998, CERN's industrial controls group developed the UNICOS framework (UNified Industrial Control System), becoming a de facto standard of industrial control systems and gradually deployed in different domains at CERN (e.g. Cryogenics, HVAC…). After an initial prototype applying the UNICOS-CPC (Continuous Process Control) framework to the controls of some vacuum installations, both teams have been working on the development of vacuum-specific objects and their integration, together with new features, into the UNICOS framework. Such convergence will allow this generic framework to better fit the vacuum systems, while offering the advantages of using a widespread and well-supported framework. This paper reports on the experience acquired in the development and deployment of vacuum specific objects in running installations, as a prototype for the vacuum controls convergence with UNICOS.

At the heart of the LCLS-II are two undulator lines: the hard x-ray (HXR) line and the soft x-ray line (SXR). The SXR line is comprised of 21 variable gap undulator segments separated by an interspace stands with a cam positioning system capable of positioning in 5 degrees of freedom (DOF). The undulator segment motion control utilizes the Aerotech Ensemble motion controller through an EPICS Soft IOC (input-output controller). Its drive system consists of a Harmonic Drive servo system with feedback from two absolute full-gap encoders. Additional Aerotech motion controllers are used to control the cam-positioning system and phase shifters of the interspace stand. The HXR line is comprised of 32 undulator segments each including an integrated interspace assembly. The segment girder is placed on two stands with a similar cam-positioning system as in the SXR line allowing for movement in 5 DOF. As one of the design goals of the HXR line was to reuse the original LCLS girder positioning system, the motion control system is an upgraded version of that original system, using RTEMS on VME with Animatics SmartMotors.

The paper describes planning and execution of large-scale maintenance campaigns of SCADA systems for CERN accelerator and technical infrastructure. These activities, required to keep up with the pace of development of the controlled systems and rapid evolution of software, are constrained by many factors, such as availability for operation and planned interventions on equipment. Experience gathered throughout the past ten years of maintenance campaigns for the SCADA Applications Service at CERN, covering over 230 systems distributed across almost 120 servers, is presented. Further improvements for the procedures and tools are proposed to adapt to the increasing number of applications in the service and reduce maintenance effort and required downtime.

With the advent of LCLS-II, SLAC must effectively and collectively plan for operation of its premiere scientific production facility. LCLS-II presents unique new challenges for SLAC, with its electron beam rate of up to 1MHz, complex bunch patterns, and multiple beam destinations. These machine advancements, along with long-term goals for automated tuning, model dependent and independent analysis, and machine learning provide strong motivation to enhance the SLAC software toolkit based on augmenting EPICS V3 to take full advantage of EPICS V4 - which supports structured data and facilitates a language-agnostic middle-ware service layer. The software platform upgrade path in support of controls, online physics and experimental facilities software for the LCLS-I/II complex is described.

The Klystron Bake Station at SLAC is a facility for baking out klystrons (high power RF amplifiers) among other equipment in preparation for installation in the linac. The scope of this project was to upgrade the 30 year old controls (based on VMS and CAMAC) to utilize PLC automation and an EPICS user interface. The new system allows for flexible configuration of the bake out schedule which can be saved to files or edited real time both through an EPICS soft IOC as well as a local touch panel HMI. Other improvements include active long term archiving of all data, COTS hardware (replacing custom-built CAMAC cards), email notification of fault states, and graphical user interfaces (old system was command line only). The first station upgraded came online in November 2016 and two more stations are planned to follow this year. Year poster discusses the improvements made and problems encountered in performing the upgrade.

The Linac Coherent Light Source II (LCLSII) is a new Free Electron Laser (FEL) facility being built as an upgrade to the existing LCLS-I and is planned for early commissioning this year (2017) and full operation in 2020. The injector laser which hits the cathode to produce the electrons for this FEL source is conceptually similar to LCLS-I, but will utilize an upgraded controls architecture in order to be compatible with the faster repetition rate (1 MHz) of the beam. This includes moving to industrial PCs from VME and utilizing SLAC designed PCIe timing cards and camera framegrabbers. This poster discusses the overall architecture planned for this installation and discusses the reasoning behind the choices of hardware and control scheme.

The ELBE Center for High-Power Radiation Sources is driven by a 35 MeV C.W. electron linear accelerator, driving diverse secondary beams, both electromagnetic radiation and particles. Its control system is based on PLCs, fast data acquisition systems and the industrial SCADA system WinCC. In the past five years, require-ments for availability and reliability increased, while at the same time many changes of the machine configuration and instrumentation needed to be handled. Improvements of the control system infrastructure concerning power supply, IT and systems monitoring have been realized and are still under way. Along with the latest WinCC upgrade, we implemented a more redundant SCADA infrastructure and continuously improved our standards for software development.

Changes in the accelerator beamline of the Heidelberg Ionbeam Therapy-Center necessitated a relevant change in the accelerator control system. Specifically the addition of a third ion source to the LEBT beamline dictated an expansion of the Virtual Accelerator structure both in the database and the DCU software. The decision to go to a virtual server infrastructure to meet the demands for better redundancy and performance prompted an overhaul of the ACS software and hardware base. Two new redundant virtualization servers and doubled storage systems helped to increase safety and system performance. To take advantage of the newer hardware and 64-bit operating systems, all software was converted to a 64 bit base. Additionally, as a quality of life and security improvement, the download and flash functionality of the ACS were updated to enhance performance and security checks for quality assurance measures. The new virtualization host server and infrastructure hardware in conjunction with the 64 bit update and ensuing efficiency increases have resulted in a safer and significantly faster ACS with higher redundancy in case of hardware failure.
