Description

The Shanghai High Repetition Rate XFEL and Extreme Light Facility (SHINE) is a high repetition rate X-ray free-electron laser facility currently under construction in Shanghai, China. Beam data synchronization plays a vital role in beam parameter analysis, performance optimization and fault diagnosis. Based on White Rabbit technology, a timing system is established to distribute synchronous trigger signals and unique bunch IDs to various beam diagnostic electronics. It covers the measurements of beam position, beam loss, beam length, beam arrival time and other relevant parameters. The system enables long-distance precise timing signal distribution over a span of 3.1 km, with the RMS jitter of trigger signals lower than 10 picoseconds. The system design scheme and experimental test results are presented in this paper.
