合肥光源(Hefei Light Source,HLS)是我国第一台专用同步辐射装置,它周围的辐射场是一个有方向性的瞬发混合场,辐射剂量水平随装置的不同运行状态而变化。针对改造后的光源,在原有单点监测系统的基础上,设计开发了一套基于Java动态页面(Java Server Page,JSP)技术的网络化辐射监测数据动态发布系统。系统用于监测HLS运行期间在工作场所和环境中产生的辐射剂量水平,并采用监测点分区化管理以及分区设定报警阈值。同时,该系统整合了加速器EPICS(Experimental Physics and Industrial Control System)系统中的流强数据,实现了加速器运行状态与辐射监测数据的比较分析。目前该系统运行状况良好,方便了管理人员和用户对合肥光源的辐射监测数据进行实时监测和历史查询,也为加速器等其他大型核装置的辐射监测数据对公众公布提供了经验。
The variation of the radiation field around accelerator is complex.Only by real-time monitoring can one learn them in detail.The traditional measurement methods have been out of date.The mini-DDL is a specific device designed for such radiation field real-time monitoring.It has huge flash memories and is small in size.It can communicate with the control PC via intranet or RS232 port.So it is suitable to be applied not only in area monitoring but also in temporary monitoring.The radiation field measurements results obtained using the Mini-DDL are introduced in this paper.
