摘要: 为了测量用于x光摄象的氧化铅摄象管的灵敏度。要求使用P20型光源。本文讨论了获得P20光源的两种方法:(1)一个涂有P20萤光粉的不聚焦不偏转的小型示波管和四套电源组成的P20型光源;(2)A光源通过三片特殊的滤光片组成的P20型光源。文章对这两种方法进行了比较。

Abstract: For testing the sensitivity of plumbicon used in x-ray camera a P20 type light source is required. There are two methods of getting P20 type light source: (1) The P20 type light source is composed of a mini-oscillotron, screen of which is coated with P20 type phosphor, and four power supplies. (2) The P20 type light source is obtained by adding three particular filters to an A light source. The performance of two sources obtained by different methods are compared. -
