摘要
多气隙阻性板室(MRPC)以其探测面积大、时间和位置分辨优异、成本低廉、探测效率高等优点,成为宇宙线散射成像径迹探测器的优良选择。为评估复用读出的MRPC探测器用于宇宙线散射成像实验的性能,搭建了一套测试标定实验平台,对12块MRPC探测器进行了完整的标定测试。经过实验研究,选定了8400 V的适宜工作高压,并分别根据“与”逻辑和“或”逻辑,评估了复用读出前后MRPC的探测效率。
MRPC has become an excellent choice for cosmic ray scattering imaging trackers due to its large detection area,good time and position resolution,low cost,and high detection efficiency.In order to evaluate the performance of the multiplexed readout MRPC detectors for cosmic ray scattering imaging experiments,a set of test and calibration experimental platform was established,and a complete calibration test was carried out on 12 MRPC detectors.In this paper,a suitable working high voltage of8400V was selected,and the detection efficiency of MRPC before and after multiplexing readout was evaluated according to the"AND"logic and"OR"logic.
