摘要

通过基于WindowsXP环境的VME数据获取系统

对MRPC束流实验中时间触发系统（T0）的光电倍增管（PMT）进行性能测试研究。从精确测试获取的PMT单光电子峰的角度出发

依据电荷谱的能量分辨率、峰谷比值、增益等条件确定PMT合适的工作高压。依据时间和幅度信息的匹配关系

对不同入射光子的数据进行挑选

进而改善测试数据的时间分辨。

Abstract

Based on a VME DAQ system under Windows XP environment

performance of a photomultiplier tube(PMTs)

which will be used in the T0 system for the beam test experiment of the MRPC(multi-gap resistive plate chamber)

were carefully measured.The high voltage of PMT was confirmed by studying its single photoelectron spectrum

from which the performance of PMT(such as energy resolution of the charge spectrum

peak-to-valley ratio and gain) could be acquired.The time resolution of T0 was improved by distributing the data with different number of photon which depend on the charge distribution
