For a low-emittance photon light source like the Taiwan Photon Source (TPS), beam stability is a very important property for high-quality photon beams. It is, however, hard to completely remove beam disturbing effects. Therefore, a feedback/feedforward system becomes an effective tool to suppress beam motion. In this report, we discuss the performance of such a system implemented at the TPS. The component performance of the feedback system has been tested to understand its bandwidth limitations.

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.

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.
