摘要: 介绍一种储存环束流位置监测系统的标定装置。这套标定装置是为NSRL二期工程储存环注入段真空盒改造而研制的。系统的标定精度达±0.01mm。该装置已用于新增注入段真空管的束流位置探测器的定标，获得了探头定标值，并根据其拟合和计算结果对注入段真空管进行了筛选，被选中的真空管已装入储存环注入段。Abstract: This article presents a BPM (Beam Position Monitor) calibration system developed for phase II of HLS (Hefei Synchrotron Radiation Light Source). The paper describes the development of the test stand and emphasizes key technique that guarantees mechanical accuracy of the system. The test equipment is of erect type and the geometric accuracy of ±0.01mm is obtained. The system has been served for calibrating BPM pickups, which are mounted in vacuum chambers of inject section. The electrical center of the BPMs is measured with respect to the geometrical center in the calibration machine. The eligible vacuum chambers have been installed in the storage ring.
