本文主要介绍,单光子测量电子倍增管增益的方法,它是利用光电子入射到第一倍增极,使第二倍增极产生次级电子发射的原理,而不是沿用以前常用的β源测量法,直流源测量法及质谱仪测量法等.其优点是简化了测量过程,且不需要在动态真空中进行.因此能成批生产,并能封装在透紫玻壳中待测.测量省时、效率高且测量结果由单板机直接计算,并打印输出.尤其适合工厂大批量生产.
In this paper, the principle of single-photon electron tube gain measurement, which is the use of photoelectrons incident to the first dynode, the second dynode generated secondary electron emission principle, rather than follow the commonly used β source measurement method, the DC Source measurement and mass spectrometry, etc. Its advantage is to simplify the measurement process, and does not need to be carried out in a dynamic vacuum.So it can be mass-produced, and can be packaged in the translucent glass bulb to be measured.Measurement time-saving, efficiency High and the measurement results directly calculated by the single-board, and print output. In particular, suitable for large-scale factory production.
