WEP03	A General Solution for Complex Vacuum System Controls	vacuum, status, GUI, feedback	30
	G. Bischof, A. M. Barbour, B. A. Sobhani, A. Walter BNL, Upton, Long Island, New York, USA
	At the National Synchrotron Light Source II (NSLS-II) there are many different ultra-high vacuum system configurations on the unique beamline end-stations. The proposed controls solution attempts to capture the requirements of all of these configurations with a single standard logic and graphical user interface. Additional design considerations include: resource management for multiple users, providing a high level of abstraction to simplify operation for users, providing a high level of flexibility to do non-standard operations, minimizing shock from pressure differentials when opening valves, supporting a variety of pumps, and maximizing pump lifetime. At NSLS-II it was determined that all vacuum configurations can be captured by the composition of three standard objects: a "rough vacuum group", and "high vacuum group", and a "smart vacuum manifold" which implements a blocking queue. These objects can be flexibly linked together to meet the needs of the beamline experiments. This solution is platform independent, but implemented and tested here using Pfeiffer vacuum pumps, Allen Bradley PLC, EPICS, and Control System Studio (CSS).

	Y.C. Yang, C.K. Chan, C.-C. Chang, J.-Y. Chuang, Y.M. Hsiao, Y.Z. Lin NSRRC, Hsinchu, Taiwan
	The Taiwan Photon Source (TPS) is a 3 GeV storage ring. A NI C-RIO controller, basic to the real-time, EPICS program, is used and designed such as to maintain ultra-high vacuum conditions and protect vacuum components. Pressure readings from ionization gauges are taken as the logic signal to control sector gate valves to protect ultra-high vacuum condition. Monitoring of vacuum components, water-cooling systems and chamber temperatures serves to protect vacuum equipment from radiation power. The evolution and status of the control system is presented in this paper.

WEP15	Recent Development of the RIKEN RI Beam Factory Control System	controls, power-supply, EPICS, cyclotron	66
	M. Komiyama, M. Fujimaki, N. Fukunishi, K. Kumagai, A. Uchiyama RIKEN Nishina Center, Wako, Japan
	We report on development of the successor of the existing controller device used for the magnet power supplies in the RIKEN Radioactive Isotope Beam Factory (RIBF). The existing controller for the magnet power supplies is operated in the Versa Module European (VME) computing machines under the Experimental Physics and Industrial Control System (EPICS) framework. The present controller has been operated stably for more than 10 years, however, it is now commercially unavailable because supply of some parts has been already terminated. In 2016, we developed a successor to have the same function essentially as the existing one, but it is designed to run in control systems constructed by programmable logic controller (PLC) modules instead of the VME computing environment, in order to achieve cost reduction and functional scalability. We confirmed that the successor was successfully controlled by using a test system. And now, we are developing a control system that can flexibly add new functions through actual operation while having all the existing functions. We will introduce the successor to the new injector LINAC system this year.

	Funding: The authors would like to thank the Swiss National Science Foundation for the financial support. The CMS Detector Control System (DCS) is implemented as a large distributed and redundant system, with applications interacting and sharing data in multiple ways. The CMS XML-RPC is a software toolkit implementing the standard Remote Procedure Call (RPC) protocol, using the Extensible Mark-up Language (XML) and a custom lightweight variant using the JavaScript Object Notation (JSON) to model, encode and expose resources through the Hypertext Transfer Protocol (HTTP). The CMS XML-RPC toolkit complies with the standard specification of the XML-RPC protocol that allows system developers to build collaborative software architectures with self-contained and reusable logic, and with encapsulation of well-defined processes. The implementation of this protocol introduces not only a powerful communication method to operate and exchange data with web-based applications, but also a new programming paradigm to design service-oriented software architectures within the CMS DCS domain. This paper presents details of the CMS XML-RPC implementation in WinCC Open Architecture (OA) Control Language using an object-oriented approach.

WEP19	TINE Release 5.0 : A First Look	controls, LabView, Windows, software	77
	P. Duval, J. Szczesny, J.T. Tempel DESY, Hamburg, Germany J. Bobnar Cosylab, Ljubljana, Slovenia M. Nikolova EMBL, Hamburg, Germany S. Weisse DESY Zeuthen, Zeuthen, Germany
	The TINE* control system evolved in great part to meet the needs of controlling a large accelerator the size of HERA, where not only the size of the machine and efficient online data display and analysis were determining criteria, but also the seamless integration of many different platforms and programming languages. Although there has been continuous development and improvement during the operation of PETRA, it has now been 10 years since the last major release (version 4). Introducing a new major release necessarily implies a restructuring of the protocol headers and a tacit guarantee that it be compatible with its predecessors, as any logical deployment and upgrade strategy will entail operating in a mixed environment. We report here on the newest features of TINE Release 5.0 and on first experiences in its initial deployment. * http://tine.desy.de

THCA1	Quest for the New Standard PSI IOC Platform	EPICS, Linux, FPGA, controls	119
	D. Anicic PSI, Villigen PSI, Switzerland
	With its four accelerator facilities the Paul Scherrer Institut (PSI) has already several decades of control system Input Output Computer (IOC) experience. The technology is moving forward fast. The older hardware is becoming obsolete: it is slow, consumes too much power, does not match new computing, networking and bus technologies, and replacements can no longer be purchased as models have been discontinued. All this forces us to opt for a new "standard" IOC platform with increasing regularity. What used to be twenty years, became ten, and is now tending towards five years. Here we present past and possible future IOC platforms which we are investigating. Feedback from the conference would be highly appreciated.

THP02	Current Status of the RAON Machine Protection System Development	PLC, controls, machine-protect, target	160
	H. Jin, Y. Choi, S. Lee IBS, Daejeon, Republic of Korea
	For the RAON accelerator that transport beams with high energy and power, a machine protection system (MPS) that protects each device from sudden beam loss is necessary. For this reason, we have been preparing for the development of the MPS with the start of the RAON accelerator construction. For effective MPS operation and stable accelerator operation, we divided the MPS into four subsystems: fast protection system, slow interlock system, run permit system, and post-mortem system. Among them, the FPGA-based fast protection system and the PLC-based slow interlock system have been tested by prototypes and are currently working on the mass production. The run permit system and the post-mortem system are also undergoing basic design and software development. In this paper, we will describe the progress of the MPS development through detailed hardware and software development in the RAON accelerator and explain the future plans.

THP12	Upgrading the Synchronisation and Trigger Systems on the Vulcan High-Power Nd:glass Laser	timing, laser, fibre-optics, experiment	187
	D.A. Pepler, I. O. Musgrave, P.B.M. Oliveira STFC/RAL, Chilton, Didcot, Oxon, United Kingdom
	The Vulcan Neodymium-Glass High-Power Laser Facility at the Central Laser Facility in the UK has been operational for over 40 years providing a world-leading and high-profile service to International researchers in the field of Plasma Physics. Over that time the Facility has had many modifications and enhancements to the buildings, the laser hardware and to the computerised control, synchronisation and timing systems. As the laser systems have developed and the user experiments have continued to become much more complex and demanding, many new operational conditions have been required. The use of four independent laser oscillators with different properties - including temporal, spectral and operating frequencies - have meant that the optical and electrical multiplexing and the timing and synchronisation systems have all had to be adapted and extended to cope with these additional needs. However, these changes have resulted in the build-up of the overall system jitter to ± 250 ps between long (ns) and short (ps) optical pulses and this is a limiting factor for time-critical experiments. This paper will present some of the key changes and improvements that have recently been made.

THP15	Design and Implementation of FPGA Based Protection System for Beam Acceleration in Linear IFMIF Prototype Accelerator	controls, FPGA, EPICS, rfq	195
	Y. Hirata, A. Kasugai QST, Aomori, Japan A. Jokinen, A. Marqueta Fusion for Energy, Garching, Germany H. Takahashi JAEA/J-PARC, Tokai-Mura, Naka-Gun, Ibaraki-Ken, Japan
	IFMIF (International Fusion Materials Irradiation Facility) Prototype Accelerator (LIPAc) has been developed, which is designed to produce a deuteron CW beam with a current of 125 mA at 9 MeV. After the injector commissioning, the LIPAc is entering in the second commissioning phase in which RFQ, MEBT, RF Power System and Beam Instrumentation (BI) systems have been integrated. The LCSs of LIPAc have been developed by European Home Team (EU-HT) and delivered with its subsystems; the CCS, including personnel and machine protection, timing, archiving and alarming, by Japanese Home Team (JA-HT). These have been implemented on the EPICS platform to mitigate the risk of incompatibility in the integration, which JA-HT and EU-HT are jointly carrying out to control the whole accelerator. In the CCS, some interlocks associated with measurement systems–chopper interlock, protection of BI systems, etc.–are implemented on FPGA and the condition of interlock triggering can be changed from EPICS OPIs depending on the beam conditions. The use of EPICS interface can add flexibility but still satisfy fast response and reliability requirement. The design and implementation will be presented.

	SuperKEKB project aims at world highest luminosity to 8x10³⁵cm^-2s^-1. To achieve the luminosity, a lot of equipment was newly constructed or upgraded. Especially, Damping Ring (DR) was newly constructed for reducing positron emittance, and was located at the middle of the injector LINAC. The DR timing system was also constructed. The synchronized timing which is generated at injector LINAC, is received at DR sub timing station and is distributed the end of some equipment, Kicker, Septum, and monitoring devices. We succeeded to generate not only synchronized timing but also beam control information such as beam gate for trigger inhibit signal and injection and extraction timing "value" via data buffer delivery. By using this method, accelerator operation became more convenient system.

	The purpose of a Low-Level Radio Frequency (LLRF) system is to control the accelerating cavity field amplitude and phase. To have better RF field stability, precise control and high noise reduction, a digital LLRF control system based on Field Programmable Gate Arrays (FPGA) was developed at NSRRC. We replaced the analog LLRF system with a digital version for the TPS booster ring at the beginning of 2018. During routine operation of the booster RF, some faults occurred when the digital LLRF operated in the energy savings mode. The performance and operational experience of the digital LLRF for the TPS booster will be presented here.

	Operating an injector of a synchrotron light source, energy efficiency is an important issue. Dipole and quadrupoles families of the booster synchrotron for Taiwan Light Source (TLS) is resonantly excited by three White circuits at 10 Hz rate. Magnet current cannot response in cycle-by-cycle basic due to resonance nature. The possibility of operation of the booster synchrotron in energy saving mode is explored. Minimizing the duration of magnet excitation without effect of the injected and extracted beam to support top-up operation for the TLS is investigated. Efforts will be presented in this report.

	A "triggered scaler" has been developed for J-PARC accelerators. It is a PLC-type scaler with memory-buffers. Number of pulsed signals is counted and stored in a cell of memory-buffer, then, each external trigger (25 Hz) shifts the pointer to the cell. The buffer size (192) is designed to store one machine-cycle (2480 ms or 5200 ms in J-PARC). Demonstrative measurements using a prototype module are reported. In addition, scheme to detect miss-trigger events are discussed.

THP23	Further Improvements in Power Supply Controller Transient Recorders for Post-Mortem Analysis of BPM Orbit Dumps at PETRA-III	controls, power-supply, status, interface	220
	P.K. Bartkiewicz, C. Gindler, G.K. Sahoo DESY, Hamburg, Germany
	PETRA-III is a 3rd generation synchrotron light source dedicated to users with 14 beamlines beginning operations in 2010. The storage ring was modified in 2014 for an additional 12 beamlines in two extensions. It is operated with several filling modes with 100mA at electron beam energy of 6 GeV. The horizontal beam emittance is 1.30 nmrad with 1% coupling. During a user run the Machine Protection System may trigger an unscheduled beam dump if transients in the magnet power supply (PS) currents are detected which are above permissible limits. PS controllers provide transient recorder data, showing differences between current set-point and readout values in a time span of several seconds around the moment of a beam loss. We describe automatic management system handling a large number of PSs, performing automatic transient recorder data readout, storing and available for offline analysis. We discuss hardware implementation of transient recorders and its configuration software, a Java GUI application used to investigate the transient behavior of different PSs, which might have been responsible for emittance growth, orbit fluctuations, or the beam dumps seen in a post-mortem analysis.

FRCA2	Development of a Task-Oriented Chatbot Application for Monitoring Taiwan Photon Source Front-End System	status, EPICS, photon, monitoring	228
	Y.Z. Lin, C.-C. Chang, Y.T. Cheng, J.-Y. Chuang, H.P. Hsueh, C.H. Huang, I.C. Sheng, Y.C. Yang NSRRC, Hsinchu, Taiwan
	In this study, we propose a task-oriented chatbot application as an interactive user interface for monitoring Taiwan Photon Source front-end system. This application can get specific information faster and improve the efficiency of the maintenance engineer’s definition of fault information when a fault occurs. The chatbot uses LINE’s Message API to provide services, and obtains information and status of the front-end system over EPICS protocol, responding to users’ needs, like a virtual assistant. At present, the application can obtain the front-end system information already in operation of Taiwan Photon Source, including x-ray beam position monitor, safety interlock system, front-end valve status, vacuum status…etc. However, in addition to the passive provision of information, this program has a fault warning function, and will actively transmit fault information to relevant personnel when a problem occurs in the safety interlock system.

FRCB4	The Application for Fault Diagnosis and Prediction of Power Supply Control Device on BEPCII	electron, power-supply, simulation, 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.

The High Energy Photon Source (HEPS) is a planned extremely low emittance synchrotron radiation based light source located in suburban Beijing which requires high precession control systems for both accelerator and beamline controls. This paper outlines the overall design for control systems, including equipment control, fast orbit feedback, machine protection, controls network, database, high-level application architecture, and physics applications. Early plans for beamline controls are also reported.

At the National Synchrotron Light Source II (NSLS-II) there are many different ultra-high vacuum system configurations on the unique beamline end-stations. The proposed controls solution attempts to capture the requirements of all of these configurations with a single standard logic and graphical user interface. Additional design considerations include: resource management for multiple users, providing a high level of abstraction to simplify operation for users, providing a high level of flexibility to do non-standard operations, minimizing shock from pressure differentials when opening valves, supporting a variety of pumps, and maximizing pump lifetime. At NSLS-II it was determined that all vacuum configurations can be captured by the composition of three standard objects: a "rough vacuum group", and "high vacuum group", and a "smart vacuum manifold" which implements a blocking queue. These objects can be flexibly linked together to meet the needs of the beamline experiments. This solution is platform independent, but implemented and tested here using Pfeiffer vacuum pumps, Allen Bradley PLC, EPICS, and Control System Studio (CSS).

The Taiwan Photon Source (TPS) is a 3 GeV storage ring. A NI C-RIO controller, basic to the real-time, EPICS program, is used and designed such as to maintain ultra-high vacuum conditions and protect vacuum components. Pressure readings from ionization gauges are taken as the logic signal to control sector gate valves to protect ultra-high vacuum condition. Monitoring of vacuum components, water-cooling systems and chamber temperatures serves to protect vacuum equipment from radiation power. The evolution and status of the control system is presented in this paper.

We report on development of the successor of the existing controller device used for the magnet power supplies in the RIKEN Radioactive Isotope Beam Factory (RIBF). The existing controller for the magnet power supplies is operated in the Versa Module European (VME) computing machines under the Experimental Physics and Industrial Control System (EPICS) framework. The present controller has been operated stably for more than 10 years, however, it is now commercially unavailable because supply of some parts has been already terminated. In 2016, we developed a successor to have the same function essentially as the existing one, but it is designed to run in control systems constructed by programmable logic controller (PLC) modules instead of the VME computing environment, in order to achieve cost reduction and functional scalability. We confirmed that the successor was successfully controlled by using a test system. And now, we are developing a control system that can flexibly add new functions through actual operation while having all the existing functions. We will introduce the successor to the new injector LINAC system this year.

The CMS Detector Control System (DCS) is implemented as a large distributed and redundant system, with applications interacting and sharing data in multiple ways. The CMS XML-RPC is a software toolkit implementing the standard Remote Procedure Call (RPC) protocol, using the Extensible Mark-up Language (XML) and a custom lightweight variant using the JavaScript Object Notation (JSON) to model, encode and expose resources through the Hypertext Transfer Protocol (HTTP). The CMS XML-RPC toolkit complies with the standard specification of the XML-RPC protocol that allows system developers to build collaborative software architectures with self-contained and reusable logic, and with encapsulation of well-defined processes. The implementation of this protocol introduces not only a powerful communication method to operate and exchange data with web-based applications, but also a new programming paradigm to design service-oriented software architectures within the CMS DCS domain. This paper presents details of the CMS XML-RPC implementation in WinCC Open Architecture (OA) Control Language using an object-oriented approach.

The TINE* control system evolved in great part to meet the needs of controlling a large accelerator the size of HERA, where not only the size of the machine and efficient online data display and analysis were determining criteria, but also the seamless integration of many different platforms and programming languages. Although there has been continuous development and improvement during the operation of PETRA, it has now been 10 years since the last major release (version 4). Introducing a new major release necessarily implies a restructuring of the protocol headers and a tacit guarantee that it be compatible with its predecessors, as any logical deployment and upgrade strategy will entail operating in a mixed environment. We report here on the newest features of TINE Release 5.0 and on first experiences in its initial deployment.

Quest for the New Standard PSI IOC Platform

D. Anicic
PSI, Villigen PSI, Switzerland

With its four accelerator facilities the Paul Scherrer Institut (PSI) has already several decades of control system Input Output Computer (IOC) experience. The technology is moving forward fast. The older hardware is becoming obsolete: it is slow, consumes too much power, does not match new computing, networking and bus technologies, and replacements can no longer be purchased as models have been discontinued. All this forces us to opt for a new "standard" IOC platform with increasing regularity. What used to be twenty years, became ten, and is now tending towards five years. Here we present past and possible future IOC platforms which we are investigating. Feedback from the conference would be highly appreciated.

For the RAON accelerator that transport beams with high energy and power, a machine protection system (MPS) that protects each device from sudden beam loss is necessary. For this reason, we have been preparing for the development of the MPS with the start of the RAON accelerator construction. For effective MPS operation and stable accelerator operation, we divided the MPS into four subsystems: fast protection system, slow interlock system, run permit system, and post-mortem system. Among them, the FPGA-based fast protection system and the PLC-based slow interlock system have been tested by prototypes and are currently working on the mass production. The run permit system and the post-mortem system are also undergoing basic design and software development. In this paper, we will describe the progress of the MPS development through detailed hardware and software development in the RAON accelerator and explain the future plans.

The Vulcan Neodymium-Glass High-Power Laser Facility at the Central Laser Facility in the UK has been operational for over 40 years providing a world-leading and high-profile service to International researchers in the field of Plasma Physics. Over that time the Facility has had many modifications and enhancements to the buildings, the laser hardware and to the computerised control, synchronisation and timing systems. As the laser systems have developed and the user experiments have continued to become much more complex and demanding, many new operational conditions have been required. The use of four independent laser oscillators with different properties - including temporal, spectral and operating frequencies - have meant that the optical and electrical multiplexing and the timing and synchronisation systems have all had to be adapted and extended to cope with these additional needs. However, these changes have resulted in the build-up of the overall system jitter to ± 250 ps between long (ns) and short (ps) optical pulses and this is a limiting factor for time-critical experiments. This paper will present some of the key changes and improvements that have recently been made.

IFMIF (International Fusion Materials Irradiation Facility) Prototype Accelerator (LIPAc) has been developed, which is designed to produce a deuteron CW beam with a current of 125 mA at 9 MeV. After the injector commissioning, the LIPAc is entering in the second commissioning phase in which RFQ, MEBT, RF Power System and Beam Instrumentation (BI) systems have been integrated. The LCSs of LIPAc have been developed by European Home Team (EU-HT) and delivered with its subsystems; the CCS, including personnel and machine protection, timing, archiving and alarming, by Japanese Home Team (JA-HT). These have been implemented on the EPICS platform to mitigate the risk of incompatibility in the integration, which JA-HT and EU-HT are jointly carrying out to control the whole accelerator. In the CCS, some interlocks associated with measurement systems–chopper interlock, protection of BI systems, etc.–are implemented on FPGA and the condition of interlock triggering can be changed from EPICS OPIs depending on the beam conditions. The use of EPICS interface can add flexibility but still satisfy fast response and reliability requirement. The design and implementation will be presented.

SuperKEKB project aims at world highest luminosity to 8x10³⁵cm^-2s^-1. To achieve the luminosity, a lot of equipment was newly constructed or upgraded. Especially, Damping Ring (DR) was newly constructed for reducing positron emittance, and was located at the middle of the injector LINAC. The DR timing system was also constructed. The synchronized timing which is generated at injector LINAC, is received at DR sub timing station and is distributed the end of some equipment, Kicker, Septum, and monitoring devices. We succeeded to generate not only synchronized timing but also beam control information such as beam gate for trigger inhibit signal and injection and extraction timing "value" via data buffer delivery. By using this method, accelerator operation became more convenient system.

The purpose of a Low-Level Radio Frequency (LLRF) system is to control the accelerating cavity field amplitude and phase. To have better RF field stability, precise control and high noise reduction, a digital LLRF control system based on Field Programmable Gate Arrays (FPGA) was developed at NSRRC. We replaced the analog LLRF system with a digital version for the TPS booster ring at the beginning of 2018. During routine operation of the booster RF, some faults occurred when the digital LLRF operated in the energy savings mode. The performance and operational experience of the digital LLRF for the TPS booster will be presented here.

Operating an injector of a synchrotron light source, energy efficiency is an important issue. Dipole and quadrupoles families of the booster synchrotron for Taiwan Light Source (TLS) is resonantly excited by three White circuits at 10 Hz rate. Magnet current cannot response in cycle-by-cycle basic due to resonance nature. The possibility of operation of the booster synchrotron in energy saving mode is explored. Minimizing the duration of magnet excitation without effect of the injected and extracted beam to support top-up operation for the TLS is investigated. Efforts will be presented in this report.

A "triggered scaler" has been developed for J-PARC accelerators. It is a PLC-type scaler with memory-buffers. Number of pulsed signals is counted and stored in a cell of memory-buffer, then, each external trigger (25 Hz) shifts the pointer to the cell. The buffer size (192) is designed to store one machine-cycle (2480 ms or 5200 ms in J-PARC). Demonstrative measurements using a prototype module are reported. In addition, scheme to detect miss-trigger events are discussed.

220

P.K. Bartkiewicz, C. Gindler, G.K. Sahoo
DESY, Hamburg, Germany

PETRA-III is a 3rd generation synchrotron light source dedicated to users with 14 beamlines beginning operations in 2010. The storage ring was modified in 2014 for an additional 12 beamlines in two extensions. It is operated with several filling modes with 100mA at electron beam energy of 6 GeV. The horizontal beam emittance is 1.30 nmrad with 1% coupling. During a user run the Machine Protection System may trigger an unscheduled beam dump if transients in the magnet power supply (PS) currents are detected which are above permissible limits. PS controllers provide transient recorder data, showing differences between current set-point and readout values in a time span of several seconds around the moment of a beam loss. We describe automatic management system handling a large number of PSs, performing automatic transient recorder data readout, storing and available for offline analysis. We discuss hardware implementation of transient recorders and its configuration software, a Java GUI application used to investigate the transient behavior of different PSs, which might have been responsible for emittance growth, orbit fluctuations, or the beam dumps seen in a post-mortem analysis.

In this study, we propose a task-oriented chatbot application as an interactive user interface for monitoring Taiwan Photon Source front-end system. This application can get specific information faster and improve the efficiency of the maintenance engineer’s definition of fault information when a fault occurs. The chatbot uses LINE’s Message API to provide services, and obtains information and status of the front-end system over EPICS protocol, responding to users’ needs, like a virtual assistant. At present, the application can obtain the front-end system information already in operation of Taiwan Photon Source, including x-ray beam position monitor, safety interlock system, front-end valve status, vacuum status…etc. However, in addition to the passive provision of information, this program has a fault warning function, and will actively transmit fault information to relevant personnel when a problem occurs in the safety interlock system.

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.
