摘　　要：目的:通过分析直线加速器的真空度下降,引起设备中断使用的故障,用简单的测量手法剖析该供电装置“EP130S Ion Pump Power Supply”,找出问题元件,快速解决故障过程,以供同业参考,以达到节省人力物力和时间。方法:当加速器的真空度下降,出现中断的连锁,以交换代替法、万用表跟踪测量真空泵供电装置上每个不同元件参数的改变。分析故障现象、根据电路指向,找出问题关键。结果:分析检查得出的数据和由交换代替法可见结果,清楚问题主要发生在真空泵供电装置上。结论:直接观察直线加速器出现的真空度下降的故障现象,首先考虑故障是否发生在真空泵供电装置上,利用交换代替法、万用表跟踪测量法,可快速了解情况,解决问题。Objective： A careful analysis of all the factors of a problem of vacuum down of Accelerator, Upon further analysis ion pump power supply by measure ways. We can find out burned up parts and can fast to solve trouble. Pass this case. Provide reference for the same profession. Methods： When vacuum down up, Inhibits showed. Checked data of parts use ways of exchange and follow up the seem measure. Analyze phenomena of trouble. We can find out problems. Results： See data pass measure and result by exchange ion pump＇s connect to ion pump PSU. Main question at ion pump PSU. Conclusion： If vacuum down up, watch phenomena of trouble. We should first think over ion pump device. Use simple check method. You can apace find out problem.
