| 摘 要： | 为了减小同步光尺寸对同步光位置检测器灵敏度的影响，合肥光源新研制了一种交错刀片型光位置检测器，并使用成熟的商业化产品Libera Photon进行后续的数据处理和输出。基于传统计算光位置信号的差比和方法，提出了比值和对数比两种新的计算方法，理论模拟了3种计算方法下交错刀片型光位置检测器的性能。在线标定结果与理论计算结果相符，并在机器研究光束线进行了初步的应用研究。

| Abstract: | In order to reduce the influence of beam size, a photon beam position monitor (PBPM) called staggered-blade PBPM was designed and installed in the machine diagnostic beamline (MDBL) at the Hefei Light Source (HLS), and Libera Photon was used for data processing and output. The ratio method and the log-ratio method were put forward based on the difference-over-sum (Δ/Σ) method. The main performances of staggered-blade PBPM were then analyzed with the three methods. The results of online calibration match well with the calculated results. Some application researches have also been done. |
