SSRF TIMING SYSTEM

摘要

In order to keep the synchronization of injection between electron emission of gun and bucket in the Boost and Storage Ring, a fast timing system with low jitter, high precise setting developed for SSRF project. Simultaneously, a slower timing system is also needed for beam diagnostic system, Top-up injection, events management system, time stamp for data processing etc. Its jitter time would be μ s up to ms. A fast timing system consists of the revolution divider, phase shifter, high precise (2ns) counter etc. It satisfies the physical running requirement and electronics jitter time has been tested successfully. The system function and tested results are described in this paper.
