FE-2同步定时触发系统设计

 CAFE-2 is a superconducting linear accelerator built by the Institute of Modern Physics of the Chinese Academy of Sciences (IMP) in 2021 to carry out research on new superheavy nuclides synthesis, chemical properties of superheavy elements, and the structure and properties of superheavy nuclei. The synchronized timing trigger system is an important subsystem of CAFE-2 and plays a key role in the operation of CAFE-2. The CAFE-2 main synchronization timing system adopts the classical event-based timing system. At the same time, in order to meet the needs of different operation timing and synchronization triggering of CAFE-2 in both accelerator commissioning and terminal operation modes, the synchronization trigger signal of the rotating target modulation is coupled with the main timing CW(Continuous-wave) trigger signal in the terminal operation mode through the design of the coupling circuit and interlocking logic. The problem of different trigger signal sources for CAFE-2 in accelerator commissioning and terminal operation modes is solved. This paper introduces the structure of CAFE-2 synchronous timing trigger system, and describes the principle and scheme of CAFE-2 synchronous timing trigger system in different operation modes.
