摘要
上海光源(Shanghai Synchrotron Radiation Facility,SSRF)光束线站安全联锁系统的目的是在光束线站运行期间,一旦出现紧急情况,安全联锁系统会及时关闭活动光子挡光器或通知储存环控制系统剔除电子束流,以保障实验人员的人身安全及光束线站的设备安全。在SSRF第一条Canted光束线安全联锁系统设计过程中,通过分析Canted光束线与常规插入件光束线在布局与安全联锁要求方面的区别,实现了Canted前端的设备联锁控制要求,并提出了利用束线仲裁信号实现两条光束线和谐相处的设计方法,最终完成了两条光束线的安全联锁系统的安装调试及其验收。Canted光束线安全联锁系统自2013年7月投入试运行以来运行正常,为光束线和实验站的正常调试提供了保障。
Background： Shanghai Synchrotron Radiation Facility（SSRF） is one of the third generation synchrotron radiation light sources in the world. Canted beamline which means two underlator are installed in one straight section is designed to increase the capacity of SSRF beamlines and thereof the interlock system for the canted beamline. Purpose： The aim of Canted beamline interlock system is to protect users and beamline components from the radiation of synchrotron light source, and ensure the Canted beamlines to run harmoniously. Methods： Based on Programmable Logic Controller（PLC）, Canted beamline interlock system puts forward beamline arbitrary signals and two searching paths to solve a series of difficulties such as the interlock relationships of shared components and shared hutch area. Results： In case of emergency, Canted beamline interlock system closes the photon shutters or requests the storage control system to abort the stored electron beam to assure personal and beamline device safety according to preset interlock logic. Conclusion： The designed Canted beamline interlock system collaborates smoothly with other control systems and works well from July 2013 till now. The design methods presented here provides reference for the following Canted beamlines in phase-II beamlines project in the near future.
