| 摘 要： | 海光源恒流注入的运行模式，需要直线加速器提供持续、稳定和高品质的束流。阐述了八条形电极束流位置探测器(BPM)的工作原理及其对直线加速器至增强器低能运输线的束流进行能散的测量，并以（微波）幅度或相位作为调节参数，采用比例积分(PI)控制算法对束流能散进行反馈控制，实现了束流能量的长期稳定性，保证了直线加速器束流的高效率注入。

| Abstract: | Top-up operation mode of Shanghai Synchrotron Radiation Facility (SSRF) needs the linac to supply a stable, continuous and high quality beam. The principle of an 8-pole strip-line-type beam position monitor (BPM) and measurement of the beam energy spread at low energy transform line from the linac to the booster are described, and a proportion and integration (PI) control algorithm is used to complete the feedback control of beam energy spread, which uses RF (radio frequency) amplitude or phase as the adjusting parameter. A long term stability of the beam energy is realized, which ensures the high rate of the beam injection of the linac. |
