Research on life test and system design for PMT photomultiplier tube

摘要:

光电倍增管(PMT)是空间光学探测应用的重要探测器件之一,由于制造工艺的限制,光电倍增管具有很强的个体差异性。设计了一套应用于星载激光大气探测雷达的光电倍增管寿命评估自动测试系统,并建立科学的测试方法与流程,通过对光电倍增管光电响应与暗电流等关键参数的试验、监测与分析,研究评估了其寿命特性。

Abstract:

Photomultiplier tube (PMT) is one of the important probe a space optical detection applications. Due to the limitation of manufacturing process, the photomultiplier tubes have great individual difference. This paper designed a set of applied in space-borne laser atmospheric detection radar automatic test system of photomultiplier tube life evaluation, and established a scientific testing methods and processes. Based on key parameters such as photomultiplier tube and dark current and photoelectric response test, monitoring and analysis, the life characteristic of photomultiplier tube was studied and evaluated .
