WEP04	Developing and Validating OPC-UA Based Industrial Controls for Power Supplies at CERN	simulation, electronics, controls, power-supply	35
	M. Ludwig, J.A.R. Arroyo Garcia, M. Bengulescu, B. Farnham, P.G.J. Gonzalez Jimenez, F. Varela CERN, Meyrin, Switzerland
	The industrial control systems of CERN’s experiments are undergoing major renovation since 2017 and well into CERN’s second Long Shutdown (LS2) until the end of 2019. Each detector power-supply control system runs several hundred software instances consisting of many different components in parallel on a large scale, broadly distinguishable as servers and clients. Our accumulated experience during LHC runs proves that some complex control issues are impossible to detect using stand-alone components on a small scale only. Furthermore, new components must be developed well before the electron-ics becomes available, without impact on operations. Moreover, during LS2, the improved and now widely established Open Protocol Communication Unified Ar-chitecture (OPC-UA) replaces OPC-DA as middleware protocol. For these reasons, we developed a simulation environment to emulate the real, and valuable, CAEN power-supply electronics underneath the OPC-UA serv-ers. This distributed simulation is configurable to mimic and exceed the nominal conditions during production and provides a repeatable setup for validation. This paper discusses the functionality and use of this simulation service.

	P. Chevtsov, D. Anicic, V.R. Arsov PSI, Villigen PSI, Switzerland M. Dach Dach Consulting GmbH, Brugg, Switzerland
	The main driving part of the X-ray free electron laser facility (SwissFEL) at the Paul Scherrer Institute (PSI) is a compact electron linear accelerator (linac). The machine is highly optimized to generate a superior FEL radiation with the lowest suitable electron beam energy. In order to meet extremely stringent SwissFEL requirements for electron beam quality and stability, a variety of beam diagnostics tools were developed and implemented at the PSI. All these tools are integrated into the SwissFEL control system. The paper describes basic control elements of the electron beam diagnostics tools and their operational performance.

	TPS is 3-GeV synchrotron light source which have opened for public users since September 2016 and now offers 400 mA top-up mode operation. The requirements of the long term orbit stability and orbit reproducibility after beam trip have been gradually more and more stringent and become a challenge from users’ request. Furthermore, the thermal effect would be expected to be worsen after 500 mA top-up operation which should deteriorate the orbit drift. The report investigates the long-term orbit stability observed from eBPM and XBPM and also evaluates the possibility of the local XBPM feedback.

THP08	Design and Implementation of Stepper Motor Control of the LINAC High Power RF System Based on FPGA	controls, GUI, FPGA, software	179
	R. Rujanakraikarn, Ch. Dhammatong, W. Phacheerak SLRI, Nakhon Ratchasima, Thailand
	In this paper, the new motion control system that governs the position of high power attenuators and phase shifters in the linac’s RF system at SLRI is described. The drive system, which was originally driven by a set of AC reversible motors, is replaced by a new set of stepper motors. The hardware selection and installation is presented in detail. The digital control circuits are designed in VHDL and implemented on a commercial Field Programmable Gate Array (FPGA) board. The main software part, implemented in MicroBlaze Microcontroller System (MCS), is coded in C to control the position of stepper motors relative to the DC voltage reference points of the hardware system. A LabVIEW GUI is designed to interface with the control system to provide reference points and display position values via RS-232 and PLC interfaces. This stepper motor control system can be used to effectively implement the phase and amplitude control system of the linac’s RF signals in the future.

FRCA1	New Collaborative Approach to Scientific Data Management with NOVA	experiment, detector, synchrotron, data-analysis	224
	W. Mexner, E. Bründermann, M. Caselle, S. Funkner, A. Kopmann, G. Niehues, N. Tan Jerome, M. Vogelgesang KIT, Eggenstein-Leopoldshafen, Germany
	Funding: Supported by Federal Ministry of Education and Research, Germany, 05K2016 Accelerator physics studies at the storage ring KARA at KIT produce terabytes of diagnostics data per day, which is recorded once and then reused on a long-term basis to answer different research questions at KIT. Finally, raw data and intermediate analysis results should be published along with scientific results. Thus storing from the very beginning the data of all analysis steps and its metadata in a central portal would be very beneficial. Similar requirements exist for synchrotron X-rayμtomography at the KIT imaging cluster and there is an interest to share the large data analysis effort. By using a new collaborative approach, the NOVA project aims to create tools, to enable an efficient use of valuable beam time. Forμtomography beamlines the project will build up a comprehensive database of various demonstrator organisms up for the morphological analysis of animals. The NOVA portal is integrated in the local data handling procedures and the datasets automatically appear in the NOVA portal as they are recorded. For both applications, accelerator diagnostics and X-ray tomography, the NOVA portal will offer new collaborative tools to enable synergetic data analysis.

FRCB4	The Application for Fault Diagnosis and Prediction of Power Supply Control Device on BEPCII	power-supply, simulation, operation, interface	236
	J. Liu, D. Wang, J.C. Wang, X.L. Wang IHEP, Beijing, People’s Republic of China
	With the widely adoption of complex electronic devices and microcircuits in accelerator system, the probability of system failure and functional failure will be enlarged. For example, the fault of the magnet power supply front-end electronics devices may cause accelerator energy instability and even lead to beam loss. Therefore, it is very necessary to diagnose and locate the device fault accurately and rapidly, that will induce the high cost of the accelerator operation. Faults diagnosis and prediction can not only improve the safety and reliability of the equipment, but also effectively reduce the equipment’s cycle costing. We applied the FMECA and testability modeling method for the PSI device, which using in BEPCII power supply control system, and evaluated the remaining life of the PSI under certain temperature and humidity condition based on the reliability model and accelerated life test.

In this paper, the new motion control system that governs the position of high power attenuators and phase shifters in the linac’s RF system at SLRI is described. The drive system, which was originally driven by a set of AC reversible motors, is replaced by a new set of stepper motors. The hardware selection and installation is presented in detail. The digital control circuits are designed in VHDL and implemented on a commercial Field Programmable Gate Array (FPGA) board. The main software part, implemented in MicroBlaze Microcontroller System (MCS), is coded in C to control the position of stepper motors relative to the DC voltage reference points of the hardware system. A LabVIEW GUI is designed to interface with the control system to provide reference points and display position values via RS-232 and PLC interfaces. This stepper motor control system can be used to effectively implement the phase and amplitude control system of the linac’s RF signals in the future.

Accelerator physics studies at the storage ring KARA at KIT produce terabytes of diagnostics data per day, which is recorded once and then reused on a long-term basis to answer different research questions at KIT. Finally, raw data and intermediate analysis results should be published along with scientific results. Thus storing from the very beginning the data of all analysis steps and its metadata in a central portal would be very beneficial. Similar requirements exist for synchrotron X-rayμtomography at the KIT imaging cluster and there is an interest to share the large data analysis effort. By using a new collaborative approach, the NOVA project aims to create tools, to enable an efficient use of valuable beam time. Forμtomography beamlines the project will build up a comprehensive database of various demonstrator organisms up for the morphological analysis of animals. The NOVA portal is integrated in the local data handling procedures and the datasets automatically appear in the NOVA portal as they are recorded. For both applications, accelerator diagnostics and X-ray tomography, the NOVA portal will offer new collaborative tools to enable synergetic data analysis.

With the widely adoption of complex electronic devices and microcircuits in accelerator system, the probability of system failure and functional failure will be enlarged. For example, the fault of the magnet power supply front-end electronics devices may cause accelerator energy instability and even lead to beam loss. Therefore, it is very necessary to diagnose and locate the device fault accurately and rapidly, that will induce the high cost of the accelerator operation. Faults diagnosis and prediction can not only improve the safety and reliability of the equipment, but also effectively reduce the equipment’s cycle costing. We applied the FMECA and testability modeling method for the PSI device, which using in BEPCII power supply control system, and evaluated the remaining life of the PSI under certain temperature and humidity condition based on the reliability model and accelerated life test.
