【摘要】 CAFE-2是中国科学院近代物理研究所于2021年建造、用于开展超重新核素合成、超重元素化学性质、超重核结构和性质等方面的研究的超导直线加速器。同步定时触发系统是CAFE-2的重要子系统，在CAFE-2的运行中起着关键性的作用。为了满足CAFE-2在加速器调试及终端运行两种运行模式下不同运行时序及同步触发的需求，CAFE-2主同步定时系统采用了经典的基于事件的定时方案，同时通过耦合电路及联锁逻辑设计，在终端运行模式下将旋转靶调制的同步脉冲信号与主定时CW(Continuous-wave)模式下的触发信号进行耦合，在不同运行模式下采用不同的工作原理与方案，解决了CAFE-2在终端运行模式下触发信号必须与旋转靶脉冲信号同步的难题。更多还原

【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.更多还原
