摘　　要：研制了新型的BLM监测系统,用于判断储存环束流损失发生的位置,以便采取措施延长束流寿命,提高机器性能指标.在进行加速器物理计算和蒙特卡罗计算后,因为簇射电子带有最强的位置信息而被确定为探测对象.该系统据此选用了对簇射电子灵敏的BLM探测器,并研制了基于CAN总线网络形式的数据采集系统;实现了对储存环束流损失的实时连续监测.连续运行多年的结果表明,该系统在分析束流损失原因和调整储存环运行参数等方面起到很好的作用.A new type of BLM （beam loss monitoring） system was developed and was used to judge the beam loss position, which is significant for increasing beam lifetime and improving machine operation status. The shower electron was determined to be the detected object since the results from accelerator physics and Monte-Carlo calculation show that it carries strong position information. The system, which consists of BLM monitors and data acquisition devices communicated with PC via CAN bus, was used to realize continuous real-time monitoring for the storage ring beam loss. The operating results of the system for many years show that it helps greatly towards to analyzing the cause of beam loss and storage ring operation parameters.
