摘要

合肥光源(HLS)电子储存环的束流水平轨道存在缓慢漂移现象,导致轨道水平漂移的主要原因是同步光热效应导致束流位置检测器(BPM)真空室水平移动。为抑制这种现象而研制的合肥光源BPM真空室位移监测系统,利用光栅位移传感器实时监测全环24个BPM真空室的位移,并将数据反馈至HLS控制系统,由控制系统对BPM的轨道测量值进行实时修正,从而提高了慢速轨道反馈系统有效性。

Abstract

The beam horizontal orbit at Hefei light source(HLS) was drifting all along while the storage ring was operating due to the drift of BPM chamber mainly caused by the thermal effect of synchrotron light.To monitor the BPM chamber motion for all BPMs,a BPM chamber motion measurement system is built in real-time to correct the reading of BPMs.The raster gauges are used to measure the displacement,and the displacement data are transmitted by RS485 serial network to an industrial personal computer which processes the data and sends them to HLS control system.The design of BPM chamber motion measurement system is described and the measurement results are given.
