摘要
目的分析和总直线加速器十多年来的故障。方法根据十多年来的故障维修记录 ,统计和分析直线加速器各阶故障率及故障特点。结果直线加速器使用早期由于机器不稳定故障率比较高 ,使用中期及其比较稳定 ,故障率比较低 ,使用后期由于零部件老化 ,故障率比较高。
Objective Analyze and summarize the troubles of linear accelerator during the past10years.Methods Accordˉing to the accelerator service record of10years,analyze the trouble rate and the characteristics of three stages.Results In the early period,the trouble rate is high,because the machine is not stable.In the middle period,the machine is stable and the trouble rate is low.In the later period,the trouble rate is high because of ageing.
