摘要/Abstract

摘要： 北京同步辐射装置(BSRF)4B7B软X射线实验站为超高真空系统,与上游光束线通过电磁插板阀连接。用户在实验中换样易发生失误操作行为,在未关闭阀门状态下,给真空系统放气,损坏仪器设备。为避免造成真空事故,提出对原手动保护措施进行优化,设计真空安全联锁保护系统。将真空计、气动角阀和电磁插板阀用电气元件联锁控制,旨在保证用户换样时实验站真空安全的基础上,提高用户操作的便捷性和可靠性。安全联锁保护系统控制柜落地后经过多次调试检验和试运行后确认符合预期设计要求,并在软X射线标定实验中正式应用。此外还探讨了安全联锁保护系统在未来高能同步辐射光源(HEPS)光束线站的应用前景,为建设HEPS光束线站真空联锁保护系统提供工程设计经验。

Abstract: Beijing synchrotron radiation facility (BSRF) 4B7B soft X-ray endstation is an ultra-high vacuum system, which is connected to the upstream beamline through an electromagnetic plug-in valve. Scientific research users are prone to misoperation when changing samples in experiment. When valve is not closed, vacuum system is vented and equipment is damaged. In order to avoid vacuum accidents, this article proposes to optimize the original manual protection measures and design vacuum safety interlock protection systems. Vacuum gauge, pneumatic angle valve, and electromagnetic flapper valve are interlocked and controlled by electrical components, aiming to improve the convenience and reliability of user's operation on the basis of ensuring the vacuum safety of endstation when user changes samples. The safety interlocking protection system control cabinet was confirmed to meet the expected design requirements after many commissioning inspections and trial runs after landing, and was formally applied in soft X-ray calibration experiment, effectively ensuring the safety and reliability of equipment during user operation. In addition, application prospect of the safety interlock protection system in beamline of high energy photon source (HEPS) in the future is discussed in this article, and engineering design experience is provided for construction of vacuum interlocking protection system of HEPS beamline.

Key words: synchrotron radiation endstation, relay control, vacuum gauge, interlocking protection system
