| 摘 要： | 为了抑制BEPCⅡ产生的耦合束团不稳定性, 提高储存环中的流强, 研制了一套逐束团横向束流反馈系统的样机并在BEPC上做了实验, 得到了理想的结果. 当束团不稳定时, 频谱仪上可以观察到横向边带, 此时将反馈系统闭环工作于阻尼状态时, 横向边带立即消失. 本文介绍了样机系统的组成、各部分的功能和实验结果.

| Abstract: | In order to cure the transverse coupled-bunch instabilities of BEPC II and improve the beam current of the rings, a prototype of transverse bunch-by-bunch feedback system was studied and made. The experiment of this prototype on the BEPC storage ring shows that this system can work well. The beam instabilities can be successfully suppressed when the feedback loop is closed. This paper describes the prototype of the transverse feedback system and the preliminary test results. |
