基于EPICS的粒子加速器辐射安全联锁PLC系统设计

Design of Particle Accelerator Safety Interlock PLC System Based on EPICS

粒子加速器是一种研究粒子结构的高能物理研究装置,在加速器调试和运行过程中,会形成瞬发辐射,一套稳定可靠的辐射安全联锁系统是粒子加速器保护人员安全的必备设施。本文以高能同步辐射光源为例,介绍了一种基于EPICS的辐射安全联锁系统,该系统以横河PLC作为联锁控制器,可以保证系统的稳定可靠和可扩展性;用加速器控制行业十分流行的EPICS软件开发监控平台,在保证系统自身安全运行的同时,可以提供必要的共享数据给加速器控制系统,便于开发各类远程显示终端。

Particle accelerator is a kind of high energy physics research device that studies particle structure.In the debugging and operation process of accelerator,prompt radiation will be formed.A stable and reliable radiation safety interlock system is the necessary facility for particle accelerator to protect the safety of personnel.Taking the High Energy Photon Source as an example,this paper introduce a radiation safety interlocking system based on EPICS,which takes yok-ogawa PLC as the interlocking controller to ensure the system stability,reliability and scalability.The EPICS software develop monitoring platform,which is very popular in the accelerator control industry,can provide necessary shared data to the accelerator control system while ensuring the safe operation of the system itself,so as to facilitate the development of various remote display terminals.
