摘要: 介绍了合肥光源基于束流准直系统的研制，该系统利用可开关的电阻分流法构成，并采用固态继电器进行四极铁分流控制。利用该系统可以测量束流位置检测器的电中心相对相邻四极铁磁中心的位置偏移。给出了合肥光源基于束流准直系统的一些测量结果。Abstract: The development of beambased alignment system for Hefei Light Source (HLS) is presented. In this system, a switchable shunt resistor was installed on quadrupole to bypass a small percentage of the magnet current, and solid-state relays were used to switch the shunt resistor. The system can be used to measure the offset of the beam position monitor (BPM) with respect to the magnetic center of a quadrupole. Some measurement results for HLS are given.
