| 摘 要： | 本文描述了银管进氧系统的结构及使用方法.并针对光电阴极的激活工艺指出了该结构存在的主要问题,即有杂质气体的引入和较长的时间响应.这对光电阴极的激活是十分不利的.为此改进了银管进氧系统的结构,采用纯氧气流保护银管的措施和适当的使用方法,从而获得了高纯氧、可控制的氧气压和极短的时间延迟,满足了光电阴极激活工艺的要求.

| Abstract: | The silver tube assembly to admit oxygen to a high vacuum activation system is described and the gas composition in vacuum system is measured with a quadrupole mass spectrometer.The experimental results show that high purity oxygen and shorter time delay for control of the oxygen pressure in a vacuum system can be obtained using silver tube assembly with some improvement. |
