摘　　要：介绍了在合肥光源研制的一套横向(x,y方向)高频、宽带逐束团测量和反馈系统,以及抑制耦合束团不稳定性的初步实验。其中重点介绍了在该系统研制过程中所涉及的部分关键技术:矢量运算模块的开发使得反馈系统的调试简易方便;Notch滤波器用于滤除反馈信号中的直流分量以及回旋频率分量,节省反馈功率;激励条带的研制。初步的反馈实验结果表明:反馈系统开启后不稳定性振荡得到抑制。This paper has introduced the development of the transverse bunch-by-bunch measurement and feedback system, including the experiment of damping the coupled bunch instability. Some key technologies on the system have been introdueedz the vector calculation module as a signal processing module used to adjust the phase of the feedback signals, the feedback kicker cavity and the notch filter used to filter the DC component and revolution frequencies component in a signal and save the feedback power. The result of the feedback experiment is mentioned., the instability oscillation was damped when the feedback system was on.
