高计数率环境下MRPC特性研究
基本信息
结项摘要
随着高能核与粒子物理的发展，实验亮度和能量不断提高，对探测器的要求也越来越高。例如德国GSI/FAIR加速器上的CBM实验，我国兰州的HIRFL-CSR外靶实验等，都需要在几k到几十kHz/cm2的粒子通量条件下，时间分辨好于100ps的飞行时间探测器来进行粒子鉴别。本项目针对这一需求，对高计数率条件下多气隙电阻板室（Multi-gap Resistive Plate Chamber, MRPC）的工作机制进行研究，通过模拟和实验等手段，找到限制MRPC计数率能力的根本原因；通过选择合适的电阻板材料、调整探测器结构设计参数等方法，把MRPC的计数率能力从几百Hz/cm2提高到20kHz/cm2以上。通过本项目的研究，最终能为高能物理实验提供一种时间分辨好（低于100ps）、探测效率高（>90%）、可以工作在高带电粒子通量条件下的造价低廉的飞行时间探测器，进一步提高我国粒子探测技术的水平。
