摘　　要：门控型微通道板光电倍增管是一种具有门选通功能的光电倍增管,采用该器件构成的探测器组件可以从强背景光中选出所需的信号,消除强激光对探测器可能造成的损害,广泛应用于核物理探测、卫星激光测距、时间相关荧光余辉测试等领域。本单位成功研制了外门控型微通道板光电倍增管组件,解决了最大脉冲线性电流的提升、门信号干扰的优化、高电子增益实现等关键技术问题。探测器组件初步应用于CSNS反角白光中子源测量,实现了门控测试功能。Gated micro-channel plate photomultiplier tube is a kind of photomultiplier tube with gated function.The detector module using this device can select the desired signal from the strong background light,and can also eliminate possible damage to itsself by strong laser.This detector can be widely used in nuclear physics detection,satellite laser ranging,time-dependent fluorescence afterglow measurement and other fields.External gated micro-channel plate photomultiplier tube modules were successively developed,and the key technical issues such as the lifting of pulsed peak current,the optimization of noise induced by gate pulse and the realization of high electron gain were also solved.The detector module is preliminarily applied to the measurement of CSNS counter-angle white light neutron source,and its gating test function is realized.
