电子加速器辐照装置清场巡检联锁的优化设计

Optimization Design of Cleaning Inspection Interlock for Electron Accelerator Irradiation Device

电子加速器运行期间,辐照室和主机室会产生多种辐照源,人员误入辐照室或主机室会受到辐射危害,为此我们必须建立性能齐全且稳定可靠的辐射安全联锁系统。清场巡检联锁是辐射安全联锁系统的重要组成部分,本文介绍清场巡检联锁的优化设计方案,将清场巡检与控制门联锁、与防人误入信号联锁、与声光报警联锁,实现了开门必须清场巡检、巡检警示和巡检过程中防人员跟随等功能,进一步完善了清场巡检,更好地保护人员的人身安全。

During the operation of the electron accelerator, a variety of radiation sources will be generated in the irradiation room and the main engine room, and personnel entering the irradiation room or the main engine room by mistake will be exposed to radiation hazards. A radiation safety interlocking system with complete performance, stability and reliability must be established. The site clearing inspection interlock is an important part of the radiation safety interlock system. This paper introduces the optimal design scheme of the site clearing inspection interlock, which interlocks the site clearing inspection with the control door, with the signal to prevent people from entering by mistake, and with audible and visual alarm. It realizes the functions of site clearing inspection when opening the door, patrol inspection alarm and patrol inspection personnel following,which further improves the site clearing inspection and better protects the personal safety of personnel.
