120 MeV电子直线加速器在线自动老练系统研制

Development of Online Automatic Conditioning System in 120 MeV Electron Linear Accelerator

为保证电子直线加速器的性能和稳定运行,需对高功率微波加速结构进行老练。针对微波系统老练效率低、时间长和实验人员工作强度大等问题,研制了基于EPICS和SNL的在线自动老练系统,系统基于现有控制系统结构开发,提高了老练效率,缩短了约25%的老练时间,同时减少了工作人员操作设备的工作强度,为后续加速器顺利出束并达到设计指标打下良好的基础。

To ensure the performance and steady operation of the electron linear accelerator,the high power micro-wave accelerating structure should be conditioned.To solve the problems of the low efficiency and long duration of conditioning and the great burdens of the operators,an online automatic conditioning system was developed using SNL with EPICS and low level structure of the accelerator control system.The automatic conditioning system improves the efficiency,shortens the conditioning duration by about 25%,and reduces the operators’burdens.It makes a good foundation for the accelerator to operate smoothly and reach the design indices.
