合肥光源横向束流反馈系统中矢量运算单元和光纤陷波滤波器的研制
Development of vector calculation function and fiber notch filter at Hefei light source
摘要
合肥光源横向束流反馈系统已经建成，着重介绍了系统中矢量运算单元和光纤陷波滤波器的研制。矢量运算单元中使用混频器控制信号的衰减，调节控制电压的大小以控制反馈信号的相位；光纤陷波滤波器创新性地提出用光纤延时制作陷波滤波器，很好地滤除了信号中的回旋频率分量，节省了反馈功率。
Abstract
The transverse bunch-by-bunch feedback system has been constructed at Hefei light source to cure and damp the coupled bunch instability. There are two important modules in the system: the vector calculation module and the notch filter. The vector calculation module is a signal processing module used to adjust the phase of the feedback signals and the notch filter can filter the revolution frequency component in a signal,which will save the feedback power.
