The control system for SHINE

다국어 초록 (Multilingual Abstract)

As the first hard X-ray free electron laser facility in China, Shanghai HIgh repetition rate XFEL aNd Extreme light facility (SHINE) has been under construction since 2018. The control system is responsible for the facility-wide device control, data acquisition, machine protection, timing, high-level applications, as well as network and computing platform. The whole facility is constructed 29m underground and has a total length of 3.11 km. The large installation geography and the excellent performance parameters necessitate the control system solving a wide breadth of technical challenges. The control system has been designed and implemented using the framework of the Experimental Physics and Industrial Control System (EPICS). Our own software and scripts for high-level application makes this framework easy to use and deploy. The Machine Protection System (MPS) based on Field Programmable Gate Array (FPGA) provides a global interlock system designed to monitor the accelerator operating conditions. The timing system based on White Rabbit provides precise clock pulse signals and hardware bunch numbers. This paper presents details of the development of the control system for SHINE, as well as some valuable monitoring and maintenance applications, technologies and methods
