摘      要：Background The timing system of BEPC-Ⅱis established based on event generator and event receiver(EVR)modules from the Micro-Research *** it works smoothly,there are some downsides;for example,the output pulses cannot be adjusted in picosecond accuracy in EVRs,and additional hardware modules besides EVR had to be developed to generate the revolution frequency of synchrotron radiation ring of BEPC-Ⅱ.Purpose The purpose is to research the technique details of event timing system and to develop hardware modules by our-selves using FPGA,based on which further improvement in BEPC-Ⅱtiming system can be *** The homemade hardware cards have run successfully and generated synchronous trigger pulses and *** jitter is under 15 ps.
