MOPHA026	Development of an Online Diagnostic Toolkit for the UPC Control System	EPICS, status, controls, toolkit	246
	H.Z. Chen, Y.-S. Cheng, K.T. Hsu, K.H. Hu, C.Y. Liao, C.Y. Wu NSRRC, Hsinchu, Taiwan
	Most IOC (Input Output Controller) platforms and servers at the TPS control system have been connected to uninterruptible power supplies (UPS) to prevent short downtime of the mains electricity. To accomplish higher availability, it is necessary to maintain batteries and circuits for the UPS system periodically. Thus, an online diagnostic toolkit had to be developed to monitor the status of the UPS system and to notify which abnormal components should be replaced. One dedicated EPICS IOC has been implemented to communicate with each UPS device via SNMP. The PV states of the UPS system are published and archived and specific graphical applications are designed to show the existing control environment via EPICS CA (Channel Access). This paper reports the development of an online diagnostic toolkit for the UPS System.

	The XrayFeed device of Karabo [1, 2] is designed to provide spatial X-ray beam stability in terms of drift compensation utilizing different diagnostic components at the European XFEL (EuXFEL). Our feedback systems proved to be indispensable in cutting-edge pump-probe experiments at EuXFEL. The feedback mechanism is based on a closed loop PID control algorithm [3] to steer the beam position measured by a so-called diagnostic devices to the desired centered position via defined actuator adjusting the alignment of X-ray optical elements, in our case a flat X-ray mirror system. Several diagnostic devices and actuators can be selected according to the specific experimental area where a beam position feedback is needed. In this contribution, we analyze the improvement of pointing stability of X-rays using different diagnostic devices as an input source for our feedback system. Different types of photon diagnostic devices such as gas-based X-ray monitors [4], quadrant detectors based on avalanche photo diodes [5] and optical cameras imaging the X-ray footprint on scintillator screens have been evaluated in our pointing stability studies.

TUBPR06	Laser Megajoule Timing System	timing, laser, target, experiment	749
	T. Somerlinck, T. Falgon CEA, LE BARP cedex, France N. Bazoge, S. Hocquet, D. Monnier-Bourdin Greenfield Technology, Massy, France
	The aim of the Laser Megajoule facility (LMJ) is to deliver more than 1 MJ of laser energy to targets for high energy density physics experiments. In association with Greenfield Technology, we developed a specific timing system to synchronize the 176 laser beams on the target with a precision better than 40 ps rms and to trigger and mark plasma diagnostics. The final architecture, settled and used since three years, is based on a master oscillator that sends a clock with serial data through a fiber-optic network, allowing to synchronize more than 500 delay generators spread over the large LMJ facility. The settings of each laser beam and the various experiments require different sampling rates (multi to single shot) and 16 groups for coactivity. Three kinds of delay generators, electrical and optical, are designed for standard precision (<150 ps jitter) and the third is designed for high precision. Each output deliver trigger or fiducial signals with jitter down to 5 ps and peak-to-peak wander less than 10 ps over a week. Test performance of this LMJ timing system is in progress all over the LMJ facility. Besides it will be installed on the petawatt laser (PETAL) this year.

TUCPL03	The LMJ Target Diagnostics Integration	target, controls, interface, software	767
	S. Tranquille-Marques, P. Prunet CEA, LE BARP cedex, 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. All this Targets Diagnostics arrived one at a time, each one with its particularity and complexity. The Tango Architecture and Panorama are used for the command control of these equipment. The aim of this paper is first, to introduce how Targets Diagnostics are progressively integrated in the command control. We will then see how Targets Diagnostics managed to cohabit even if they are in different phases of their integration. The paper concludes how Target Diagnostics are configured and computer-driven during all the shot sequence.

WEPHA095	Managing Archiver Rules for Individual EPICS PVs in FRIB’s Diagnostics System	EPICS, controls, interface, LEBT	1312
	B.S. Martins, S. Cogan, S.M. Lidia, D.O. Omitto FRIB, East Lansing, Michigan, USA
	Funding: This material is based upon work supported by the U.S. Department of Energy Office of Science under Cooperative Agreement DE-SC0000661, the State of Michigan, and Michigan State University. The Beam Instrumentation and Measurements group at the Facility for Rare Isotope Beams is responsible for maintaining several EPICS IOC instances for beam diagnostics, of different IOC types, which end up generating tens of thousands of PVs. Given the heterogeneity of Diagnostics devices, the need to archive data for scientific and debugging purposes, and space limitations for archived data storage, there is a need for having per-PV (as opposed to per-Record) archiving rules in order to maximize utility and minimize storage footprint. This work will present our solution to the problem: "IOC Manager", a custom tool that leverages continuous integration, a relational database, and a custom EPICS module to allow users to specify regular-expression based rules for the archiver in a web interface.

WEPHA131	Evaluation of an SFP Based Test Loop for a Future Upgrade of the Optical Transmission for CERN’s Beam Interlock System	operation, network, hardware, monitoring	1399
	R. Secondo, M.A. Galilée, J.C. Garnier, C. Martin, I. Romera, A.P. Siemko, J.A. Uythoven CERN, Meyrin, Switzerland
	The Beam Interlock System (BIS) is the backbone of CERN’s machine protection system. The BIS is responsible for relaying the so-called Beam Permit signal, initiating in case of need the controlled removal of the beam by the LHC Beam Dumping System. The Beam Permit is encoded as a specific frequency traveling over a more than 30 km long network of optical fibers all around the LHC ring. The progressive degradation of the optical fibers and the aging of electronics affect the decoding of the Beam Permit, thus potentially resulting in an undesired beam dump event and by this reduce the machine availability. Commercial off-the-shelf SFP transceivers were studied with the aim to improve the performance of the optical transmission of the Beam Permit Network. This paper describes the tests carried out in the LHC accelerator to evaluate the selected SFP transceivers and it reports the results of the test loop reaction time measurements during operation. The use of SFPs to optically transmit safety critical signals is being considered as an interesting option not only for the planned major upgrade of the BIS for the HL-LHC era but also for other protection systems.

WEPHA133	Sirius Diagnostics IOC Deployment Strategy	EPICS, controls, software, network	1407
	L.M. Russo LNLS, Campinas, Brazil
	Sirius beam diagnostics group is responsible for specifying, designing and developing IOCs for most of the diagnostics in the Booster, Storage Ring and Transport Lines, such as: Screens, Slits, Scrapers, Beam Position Monitors, Tune Measurement, Beam Profile, Current Measurement, Injection Efficiency and Bunch-by-Bunch Feedback. In order to ease maintenance, improve robustness, repeatability and dependency isolation a set of guidelines and recipes were developed for standardizing the IOC deployment. It is based on two main components: containerization, which isolates the IOC in a well-known environment, and a remote boot strategy for our diagnostics servers, which ensures all hosts boot in the same base operating system image. In this paper, the remote boot strategy, along with its constituent parts, as well as the containerization guidelines will be discussed.

THCPR03	A Safety Rated FPGA Framework for Fast Safety Systems	FPGA, PLC, electron, hardware	1626
	F. Tao, B.M. Bennett, D.G. Brown, J. Jones, M.W. Stettler SLAC, Menlo Park, California, USA
	In this paper, we will introduce a generic safety-rated FPGA design template. FMEDA analysis, hardware reliability modeling, firmware development, verification and validation will be described in details to demonstrate the IEC 61508 compliant development process. In this dual redundant design, each chain consists a FPGA chip from different manufacturers to minimize the potential common cause failures. Cross checks between FPGAs and end-to-end self-checks are performed to increase the diagnostic coverage and improve the reliability. Based on this safety FPGA template, an Average Current Monitor (ACM) system is developed at SLAC with the addition of a safety PLC for diagnostics and a HMI for user interface. The overall system is deployed as part of Beam Containment System (BCS) to limit the beam current with the target Safety Integrity Level (SIL) 2.

FRAPP01	The Laser MegaJoule Facility: Command Control System Status Report	target, controls, laser, MMI	1652
	H. Durandeau, R. Clot, P. Gontard, S. Tranquille-Marques, Y. Tranquille-Marques CEA, LE BARP cedex, France
	The Laser MegaJoule (LMJ) is a 176-beam laser facility, located at the CEA CESTA Laboratory near Bordeaux (France). It is designed to deliver about 1.4 MJ of energy on a target, for high energy density physics experiments, including fusion experiments. The first bundle of 8-beams bundle was commissioned in October 2014. Today five bundles are in operation. In this paper, we focus on two specific evolutions of the command control: the Target Chamber Diagnostic Module (TCDM) which allows the measurement of vacuum windows damages (an automatic sequence activates the TCDM that can be operated at night without any operator) and new Target Diagnostics integration. We also present a cybersecurity network analysis system based on Sentryo Probes and how we manage maintenance laptops in the facility.

This work will present our solution to the problem: "IOC Manager", a custom tool that leverages continuous integration, a relational database, and a custom EPICS module to allow users to specify regular-expression based rules for the archiver in a web interface.

Funding: This material is based upon work supported by the U.S. Department of Energy Office of Science under Cooperative Agreement DE-SC0000661, the State of Michigan and Michigan State University.
The Beam Instrumentation and Measurements department is responsible for dozens of different diagnostics devices deployed at multiple locations at the Facility for Rare Isotope Beam. In order to manage such a high number of devices, different tools were created to address preventive and corrective maintenance tasks and check the overall health of the equipment. This work will present how the EPICS tools and frameworks, such as archiver, channel finder, and pyDevSup, were integrated with our environment to help achieve a high availability for the beam diagnostic devices.

The Beam Interlock System (BIS) is the backbone of CERN’s machine protection system. The BIS is responsible for relaying the so-called Beam Permit signal, initiating in case of need the controlled removal of the beam by the LHC Beam Dumping System. The Beam Permit is encoded as a specific frequency traveling over a more than 30 km long network of optical fibers all around the LHC ring. The progressive degradation of the optical fibers and the aging of electronics affect the decoding of the Beam Permit, thus potentially resulting in an undesired beam dump event and by this reduce the machine availability. Commercial off-the-shelf SFP transceivers were studied with the aim to improve the performance of the optical transmission of the Beam Permit Network. This paper describes the tests carried out in the LHC accelerator to evaluate the selected SFP transceivers and it reports the results of the test loop reaction time measurements during operation. The use of SFPs to optically transmit safety critical signals is being considered as an interesting option not only for the planned major upgrade of the BIS for the HL-LHC era but also for other protection systems.

Sirius beam diagnostics group is responsible for specifying, designing and developing IOCs for most of the diagnostics in the Booster, Storage Ring and Transport Lines, such as: Screens, Slits, Scrapers, Beam Position Monitors, Tune Measurement, Beam Profile, Current Measurement, Injection Efficiency and Bunch-by-Bunch Feedback. In order to ease maintenance, improve robustness, repeatability and dependency isolation a set of guidelines and recipes were developed for standardizing the IOC deployment. It is based on two main components: containerization, which isolates the IOC in a well-known environment, and a remote boot strategy for our diagnostics servers, which ensures all hosts boot in the same base operating system image. In this paper, the remote boot strategy, along with its constituent parts, as well as the containerization guidelines will be discussed.

In this paper, we will introduce a generic safety-rated FPGA design template. FMEDA analysis, hardware reliability modeling, firmware development, verification and validation will be described in details to demonstrate the IEC 61508 compliant development process. In this dual redundant design, each chain consists a FPGA chip from different manufacturers to minimize the potential common cause failures. Cross checks between FPGAs and end-to-end self-checks are performed to increase the diagnostic coverage and improve the reliability. Based on this safety FPGA template, an Average Current Monitor (ACM) system is developed at SLAC with the addition of a safety PLC for diagnostics and a HMI for user interface. The overall system is deployed as part of Beam Containment System (BCS) to limit the beam current with the target Safety Integrity Level (SIL) 2.

The Laser MegaJoule (LMJ) is a 176-beam laser facility, located at the CEA CESTA Laboratory near Bordeaux (France). It is designed to deliver about 1.4 MJ of energy on a target, for high energy density physics experiments, including fusion experiments. The first bundle of 8-beams bundle was commissioned in October 2014. Today five bundles are in operation. In this paper, we focus on two specific evolutions of the command control: the Target Chamber Diagnostic Module (TCDM) which allows the measurement of vacuum windows damages (an automatic sequence activates the TCDM that can be operated at night without any operator) and new Target Diagnostics integration. We also present a cybersecurity network analysis system based on Sentryo Probes and how we manage maintenance laptops in the facility.
