Abstract： 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.

Abstract： The accelerator vacuum monitoring system is an important subsystem in the accelerator control system, which plays an important role in maintaining the normal operation of the accelerator. The design, development and development process of traditional large-scale control systems are highly dependent on physical entities, and the functional testing and performance verification of the whole system are all concentrated in the late stage of the project, resulting in a long development cycle of the control system, higher risks, and a tight time for late field debugging. To this end, industrial virtual debugging and virtual machine technologies were introduced to build a full-level virtual simulation debugging platform for the accelerator vacuum monitoring system. In the early stage of development, parallel collaborative development, full-level virtual debugging and logic rehearsal of the accelerator air monitoring system began to be carried out. Finally, the debugging results were applied to the site through on-site configuration, significantly shortening the time of on-site debugging. Reduce equipment loss and commissioning risk, improve project implementation efficiency and engineering design reliability.
