Abstract: CAFE-2, a superconducting linear accelerator built by the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences in 2021, is designed to research the synthesis of new superheavy nuclides, the chemical properties of superheavy elements, and the structure of superheavy nuclei. Its synchronized timing trigger system plays a key role in its operation. To meet CAFE-2's timing and synchronization requirements during accelerator commissioning and endstation operation, the main timing system employs a classic event-based scheme. Through coupled circuits and interlock logic design, it synchronizes pulse signals from the rotating target modulation with trigger signals in the main timing CW(Continuous-wave) mode. By adapting to different operational modes, the system synchronized the trigger signals in terminal operation mode with the pulse signals from the rotating target.
