摘　　要：兰州重离子加速器(简称HIRFL),是我国规模最大、加速离子种类最多、能量最高的重离子研究装置,可提供单核子能量达GeV量级的重离子束。HIRFL运行时,束流会在加速器隧道内产生辐射,需要建立一套人身安全联锁系统来保障人员的辐射安全。HIRFL人身安全联锁系统遵循分区联锁、硬件最可靠、失效保护、冗余及独立性、自锁等设计原则,选用了可靠性高的冗余PLC作为核心控制器,并使用了安全性高的联锁部件。本工作的完成保障了HIRFL工作人员的辐射安全,也为同类型加速器装置的人身安全联锁系统设计提供了参考。The Heavy Ion Research Facility in Lanzhou(HIRFL)is the largest heavy ion research facility in China,which has the most kinds of accelerated ions and the highest energy.Radiation will be generated in the accelerator tunnel during the operation of HIRFL,so it is necessary to establish a radiation safety interlock system to ensure the radiation safety of the workers.The system folows the design principles of zone partition interlocking,reliable hardware,failure protection,redundancy and independence,self-locking,etc.Redundant PLCs with high reliability are used as the central controller and interlocking components with high safety are selected.The successful establishment of the radiation safety interlock system is of great significance to the radiation safety of the staff at HIRFL,and it can also provide a reference for the design of interlock systems of other accelerators.
