瓦里安23EX加速器内循环水系统及其常见故障的分析

为保证医用直线加速器工作性能稳定的水循环恒温系统是加速器的重要组成部分,尽管不同加速器的内循环水系统不完全一样,但其原理相通、结构大同小异。对于加速器的维护人员来说,熟知内循环水系统的原理和结构,准确、快速判断并修复系统经常出现的故障,对提高加速器的开机率、延长其使用寿命具有一定的重要意义。

Analysis of common breakdowns of inner-circulating water system in Varian 23EX accelerator

The water circulation system is an important part of the accelerator. Its stability is a basis to ensure the stable performance of the linear accelerator. Although the circulation water in different systems is not all the same exactly, they have similarities both in principle and structure. For the accelerator maintenance operator should be familiar with the circulating water system within the principles and structure and how to diagnose and fix the malfunction in frequent accurately and timely. Meanwhile, he/she should have a certain sense to improve the service life and the ratio in operation.
