摘　　要：目的:研究BJ-6B加速器高压调制器闸流管故障判断、排除方法以及保养方法。方法 :分析2001年11月至2011年3月氢闸流管故障现象、处理方法的记录资料。结果:10 a共用4只氢闸流管。2只国产闸流管使用高压小时分别为1 095,1 635;2只英国产e2v闸流管使用的高压小时分别为1 547、1 070。使用中故障主要表现为闸流管不导通、连续导通、打火、丢失脉冲等。结论:工作中应密切注意闸流管灯丝电压的准确、稳定性,阴极应接地良好。Objective To study the way of trouble judgment,fixation and usual maintenance of thyratron in BJ-6B accelerator.Methods The maintenance records of BJ-6B accelerator＇s thyratron were analyzed retrospectively,including trouble phenomena,causes and fixation from 2001 to 2011.Results In the past 10 years,the working life in high-voltage-hour for the 2 thyratrons made in China was 1095 and 1635 respectively;and that for the other 2 thyratrons made in UK was 1547 and 1070 hours.The main troubles were that thyratron did not break through or broke through continuously,sparkle,pulse losing etc.Conclusion thyratron filament voltage must be accurate and stable,and the cathode must keep good grounding.[Chinese Medical Equipment Journal,2012,33（6）：94-95]
