利用ICCD定位宇宙线来测量探测器时间分辨的方法研究
The study of time-resolved measurement using ICCD positioning cosmic rays
摘要
Abstract
Double layers of 150 mm×150 mm plastic scintillator arrays are used to locate the cosmic ray.Both layers of arrays are read out by wavelength-shifting fibers,which are bundled and coupled to image intensifier and ICCD camera.The light signal is delayed more than 200 ns by the image intensifier,so the ICCD can be pre-triggered by an external fast coincident signal.This cosmic ray positioning system is used to measure the time resolution and photon transfer time of the time-of-fly detector for the common test platform based on cosmic ray.Compared with traditional cosmic rays test,the data-taking efficiency of this system increases more than 30 times because of multi-point readout and higher position resolution.The test results show that the time resolution of the time-of-fly detector is better than 200 ps,which satisfies the requirement of the common platform based on cosmic ray.关键词
