基于EPICS的自由电子激光THz源控制系统

Free Electron Laser-THz control system based on EPICS

摘要:

介绍了自由电子激光THz源控制系统的组成和结构，对实验物理和工业控制系统(EPICS)在注入器控制系统、磁压缩控制系统和消色散传输控制系统中的应用进行了研究，详细分析了控制系统硬件结构及软件实现。对ASYN和StreamDevice软件包开发串口设备和GPIB设备支持模块进行了研究，并将其应用于串口和带GPIB接口的设备中，实现了注入器系统、磁压缩系统和消色散传输系统的EPICS控制。EPICS的成功应用为自由电子激光THz源控制系统的升级和整合做好了前期准备工作。

Abstract:

This paper describes a control system of Free Electron Laser(FEL)-THz，which is a distributed control system based on Experiment Physics and Industrial Control System(EPICS). It gives detailed description of the injector control system，magnetic bunch compressor system and transport control system，including the hardware structure and software design. It also describes the process of creating device support module for the GPIB device and RS232 serial device. The implementation provides preparations for the upgrade of the FEL-THz control system.
