4MV静电加速器调试中出现的问题

Problems Arising in Developing 4 MV Electrostatic Accelerator

摘要: 介绍了静电加速器的结构以及调试中出现的离子源不放电、控制系统失灵和加速管破裂等技术问题，分析了出现这些问题的原因以及解决办法，调试出了流强为100μA、能量在3MeV以上的稳定质子流。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 accelerating tube cracks et al. , are introduced; the reasons and the solving means of these problems are analyzed; a stable proton beam with 100 μA and 3 MeV is obtained.
