介绍静电加速器的结构以及调试中出现的离子源不放电、控制系统失灵、加速管破裂等技术问题,分析出现这些问题的原因以及解决办法,研究了绝缘气体的成分、压力以及湿度对加速器耐压特性的影响,在11．5MPA由氮气、二氧化碳和六氟化硫组成的绝缘气体(其体积比为75: 20:5)下,得到了3．1MEV、106ΜA稳定的质子束。
This paper introduces the structure of electrostatic accelerator and the technical problems such as non-discharge of ion source, control system failure and accelerating tube rupture, and analyzes the causes and solutions of these problems. The effects of composition, pressure and humidity of insulating gas on the pressure resistance of accelerator The 3.1 MEV and 106MA stable proton beams were obtained at 11.5 MPA of insulating gas composed of nitrogen, carbon dioxide and sulfur hexafluoride in the volume ratio of 75: 20: 5.
