摘　　要：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。The structure of electrostatic accelerator and some technical problems arising in development, including the RF ion source doesn＇ t produce discharge, the controlling system is out of order and the accelerator tube cracks etc, are introduced ; the reasons and the solving means of these problems are analyzed; the effects of gas composition, pressure and humidity on the voltage of electrostatic accelerator are studied; a stable proton beam with 106μA and 3.1 MeV is developed under the condition that the pressure of the insulating mixed gas of N2 , CO2 and SF6 （75 ： 20：5 in volume） is 11. 5MPa.
