MOPGF039	TIP: An Umbrella Application for all SCADA-Based Applications for the CERN Technical Infrastructure	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.

	L. Fröhlich, B. Beutner, W. Decking, O. Hensler, R. Kammering, T. Limberg, S.M. Meykopff, J. Wilgen DESY, Hamburg, Germany
	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.

	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.

MOPGF103	The Upgrade of Control Hardware of the CERN NA62 Beam Vacuum	318
	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.

MOPGF104	Consolidations on the Vacuum Controls of the CERN Accelerators, During the First Long Shutdown of the LHC	322
	P. Gomes, F. Antoniotti, F. Aragon, F. Bellorini, S. Blanchard, J-P. Boivin, N. Chatzigeorgiou, F. Daligault, R. Ferreira, J. Fraga, J. Gama, A. Gutierrez, P. Krakówski, H.F. Pereira, G. Pigny, P.P. 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.

MOPGF105	Device Control Database Tool (DCDB)	326
	P.A. Maslov, M. Komel, M. Pavleski, K. Žagar Cosylab, Ljubljana, Slovenia
	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).

MOPGF110	Design Strategies in the Development of the Italian Single-dish Control System	330
	A. Orlati, M. Bartolini, S. Righini INAF - IRA, Bologna, Italy M. Buttu, A. Fara, C. Migoni, S. Poppi INAF - OAC, Selargius (CA), Italy
	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.

	A. Panov, A.A. Korepanov BINP SB RAS, Novosibirsk, Russia
	MAX IV and Solaris are new synchrotrons third generation. MAX IV synchrotron consist of 1.5 GeV storage ring, 3.0 GeV storage ring and linac; it is located in Lund, Sweden. Solaris synchrotron is a replica of the 1.5 GeV storage ring of the MAX IV project; it is located in Kraków, Poland. Structure of storage rings contains several pulse magnets (kicker and pinger). Control system of pulse power supplies based on LTR crate with several modules (ADC, DAC, input/output registers etc.). LTR crate is product Russian firm L-CARD. LTR crate is crate with integrated controller (ADSP Blackfin BF537) and PLC EP1C30 with direct connection to modules. In order to communicate with crate native LTR-server is used. LTR-server is a Windows application based on use of sockets. Control system of MAX IV and Solaris uses TANGO. For integration LTR-crates in final structure, special software gateway (csMAXIVltr) is used. This gateway is a set of several specific Windows applications implemented by using Qt5 libraries. Gateway allow communicating TANGO- server with crate through built-in HTTP-server. In final structure of control system csMAXIVltr will be work on a Windows virtual machine.

MOPGF112	Measurements, Alarms and Interlocks in the Vacuum Control System of the LHC	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	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	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	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.

	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	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	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	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.

TUD3I01	The LMJ Target Diagnostics Control System Architecture	565
	S. Perez, T. Caillaud CEA, Arpajon, France
	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.

	Funding: Work supported by the European Regional Development Fund and the European Social Fund under Operational Programs ECOP and RDIOP. 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.

TUD3O03	REMUS: The new CERN Radiation and Environment Monitoring Unified Supervision	574
	A. Ledeul, G. Segura, R.P.I. Silvola, B. Styczen, D. Vasques Ribeira CERN, Geneva, Switzerland
	The CERN Health, Safety and Environment Unit is mandated to provide a Radiation and Environment Monitoring SCADA system for all CERN accelerators, experiments as well as the environment. In order to face the increasing demand of radiation protection and continuously assess both the conventional and the radiological impact on the environment, CERN is developing and progressively deploying its new supervisory system, called REMUS - Radiation and Environment Monitoring Unified Supervision. This new WinCC OA based system aims for an optimum flexibility and scalability, based on the experience acquired during the development and operation of the previous CERN radiation and environment supervisory systems (RAMSES and ARCON). REMUS will interface with more than 70 device types, providing about 3,000 measurement channels (approximately 500, 000 tags) by end 2016. This paper describes the architecture of the system, as well as the innovative design that was adopted in order to face the challenges of heterogeneous equipment interfacing, diversity of end users and non-stop operation.

	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.

	Funding: This work is supported by the Helmholtz Validation Fund HVF-0016 "MTCA.4 for Industry". Porting complex device servers from one control system to another is often a major effort due to the strong code coupling of the business logic to control system data structures. 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.

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 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.

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.

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.

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.

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.

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.

CAN Over Ethernet Gateways: A Convenient and Flexible Solution to Access Low Level Control Devices

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.

Stripping Foil Displacement Unit Control for H⁻ Injection in PSB at CERN

363

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 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 CERN Health, Safety and Environment Unit is mandated to provide a Radiation and Environment Monitoring SCADA system for all CERN accelerators, experiments as well as the environment. In order to face the increasing demand of radiation protection and continuously assess both the conventional and the radiological impact on the environment, CERN is developing and progressively deploying its new supervisory system, called REMUS - Radiation and Environment Monitoring Unified Supervision. This new WinCC OA based system aims for an optimum flexibility and scalability, based on the experience acquired during the development and operation of the previous CERN radiation and environment supervisory systems (RAMSES and ARCON). REMUS will interface with more than 70 device types, providing about 3,000 measurement channels (approximately 500, 000 tags) by end 2016. This paper describes the architecture of the system, as well as the innovative design that was adopted in order to face the challenges of heterogeneous equipment interfacing, diversity of end users and non-stop operation.

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.

Porting complex device servers from one control system to another is often a major effort due to the strong code coupling of the business logic to control system data structures. 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.
