摘要
合肥光源原有的辐射监测系统是为衰减运行模式而设计建造的。为了更好地促进用户实验的科研产出,合肥光源正在进行恒流运行关键系统改造。在改造中,为了保障实验人员和设备的安全,根据恒流运行要求增加了辐射剂量监测点和完善了安全联锁功能。系统基于EPICS开发,由探测器、通讯模块、数据采集监测软件、数据分析系统等组成。该系统既能监测光源区及周边的辐射剂量率水平,还具备计算积分剂量、历史剂量查询以及必要的安全联锁等功能。新系统已经运行三个多月,系统稳定可靠,能很好地满足合肥光源恒流运行模式对辐射监测的要求。
The old radiation dose rate monitor system of the Hefei Light Source （HLS） was designed for the de- cay operation mode. To better serve for user experiments, the HLS is undergoing an upgrade for the top - off operation mode. In order to meet the requirement of the top - off operation, the radiation dose rate monitor sys- tem is overhauled in the upgrade. The new system is developed based upon the Experimental Physics and Indus- trial Control System （EPICS）, and is comprised of the detectors, communication modules, data sampling and monitoring software, and data analysis system. This system can be used not only to monitor the radiation dose rate in the light source and surrounding areas, but also to perform integral dose calculation, history data query and interlock protections. More than three months of operation indicates that this system is reliable and well ful- fills the demand of the top - off operation of the HIS.
