摘　　要：纵向束流反馈系统是近年来国际上迅速发展并广泛应用的抑制储存环纵向耦合束团不稳定性的方法 ,冲击器是其中的关键部件之一 .结合BEPCⅡ设计参数 ,研制了纵向束流反馈冲击器模型腔 ,并且利用同轴线法测量了该模型腔的阻抗和带宽 ,满足设计要求 .该模型腔设计采用脊波导加载带鼻锥的pillbox腔体的方案 ,束流管道设计为BEPCⅡ标准跑道形 .Longitudinal beam feedback system is widely used to damp coupling bunch instability. Kicker is one of the key components of the longitudinal feedback system. A prototype cavity of longitudinal feedback kicker is developed according to the parameter of BEPCⅡ. The usage of nose cone in the kicker design increased the shunt impedance. In order to avoid the extra tapper in the storage ring, the racetrack shape beam pipe is applied in the kicker. The impedance and the bandwidth of the kicker is measured by the coaxial line impedance measurement platform and the result achieved the design goals.
