摘要: 介绍了一种用于合肥光源的二分割三角型光位置检测器的设计，进行了位置信号的两种处理方法（和差比与对数比）的比较。对光位置检测器进行了测试和标定，测量结果与理论分析相当吻合。光位置检测器已成功地应用于软X射线磁性圆二色(MCD)光束线，如进行光位置稳定性测量和慢速局部反馈，给出了这些应用的结果。Abstract: This paper describes the design of a split photon beam position monitor at HLS (Hefei Light Source). Two methods of position processing are given and compared. The monitor is tested and calibrated, the results are well matched with the computed results. The photon beam position monitor has been successfully used to soft X-ray Magnetic Circular Dichroism(MCD) beam-line U18, such as the measurement of orbit stability and the slow local orbit feedback. The results of these applications are given.
