一种精密触发定时系统
A Precise Trigger Timing System
【摘要】 提出并研制了一种精密触发定时系统 .它主要利用多个光电倍增管和闪烁体组成的探测系统 ,对同一事件的时间信息进行多次测量 .通过对多个时间信息的离线处理 ,来获得时间分辨为 57ps的精密触发定时系统 .该系统可以用于快时间探测器性能的研究 .
【Abstract】 Four plastic scintillators coupled with three photo multiplier tubes (PMTs) were used to construct a preecise trigger timing system. When one charged particle passes through the system, the PMTs can measure its time information independently. By off line data analyzing, a precise trigger timing with resolution about 57ps has been gotten. This system can be used to research the time resolution of detectors.
