WEP03	A General Solution for Complex Vacuum System Controls	vacuum, GUI, operation, 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).

WEP27	Development of the Malfunctions Detection System at Vepp-2000 Collider	software, controls, collider, interface	99
	O.S. Shubina, A.I. Senchenko, P.Yu. Shatunov BINP SB RAS, Novosibirsk, Russia A.I. Senchenko NSU, Novosibirsk, Russia
	In 2007, the creation of the electron-positron collider VEPP-2000 was completed at the Institute of Nuclear Physics of the SB RAS. VEPP-2000 collider facility consists of various subsystems, and a failure of any subsystem can lead to the incorrect operation of the complex for several hours or even days. Thus, there is a need to create software that, based on the data analysis, will warn about possible malfunctions. To accomplish the task, software was developed consisting of three modules. The first performs automatic verification of compliance data obtained from the accelerator complex and rules describing the correct subsystems operation. The second module is a user-friendly web interface that displays information about the state of the complex in a convenient way. The third module acts as some intermediary between the first and the second. It processes messages arriving at the message queue and redirects them to all subscribed clients via the web socket. This article is devoted to the development of test software, which is currently running on the VEPP-2000 control panel.

	S. Yamada J-PARC, KEK & JAEA, Ibaraki-ken, Japan
	J-PARC Main Ring (MR) is a high-intensity proton synchrotron whose control system is developed based on EPICS.　It started its beam operation in 2008, and since 2009 has been delivering beam to the T2K neutrino experiment and hadron experiments.　Over the past decade, MR have become more sophisticated and more stable driving is required.　Along with this, demands arose from users and experts of equipment such that acquiring detailed and real-time information on the apparatus from the office LAN.　On the other hand, the accelerator control system is quarantined from the office LAN with firewall for security reasons.　Therefore, despite being intentional or not, manipulating any equipment in the accelerator control LAN shall be prohibited from the office LAN.　This article describes construction and prospects of such an one-way gateway system such that information is relayed via EPICS from accelerator control LAN to the office LAN while minimizing influence in the opposite direction.

	A front end (FE) safety interlock control system was designed to protect humans and the machine integrity during operation. Since stability and reliability are an important requirement in this system, we developed a FPGA based system to control a safety logic for interlock protection. The integration of the FPGA, Real-time and redundant fail-safe system in the FE interlock system enables us to provide a safe protection with EPICS com-munication and hardware protection functions.

THP23	Further Improvements in Power Supply Controller Transient Recorders for Post-Mortem Analysis of BPM Orbit Dumps at PETRA-III	controls, power-supply, operation, 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	EPICS, photon, operation, monitoring	228

	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.

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.
