BEPCII横向束流反馈系统前端电子学

Front-end electronics for BEPCII transverse feedback system

选择了一台商业化的前端电子学RFTF(radiofrequencyfrontendfortransversefeedbacksystem)用于BEPCII横向束流反馈系统,这是跟进世界先进加速器技术的具体实施。在BEPC同步运行模式下对RFTF的性能进行了测试实验,结果表明使用RFTF可以得到理想的波形,能够满足BEPCII横向反馈系统的需要,但是,当储存环出现不稳性时,系统无法正常工作,这就要求BEPCII纵向不稳定很小或者用纵向反馈系统来抑制存在的纵向不稳定。

The signal detection system is an important part for BEPCII transverse feedback system. A commercial front-end RFTF (radio frequency front-end for transverse feedback system) was bought for this system. Two working modes and the remote control are its advantages. To test the performance and master the use of it, experiments on the BEPC with the bunch-by-bunch mode were carried out. The experiment results indicate that using this facility can acquire ideal wave for BEPCII while it doesn't work when the longitudinal instability emerges, the longitudinal instability must be suppressed.
