摘要: 中国科学院近代物理研究所设计的工作频率为325 MHz、最优β为0.52 的双柱超导Spoke 腔的电磁已经完成。详细地描述了Spoke 基部横截面形状和大小对腔体射频性能的影响，采用了跑道形来取代通常的圆形Spoke 基部截面。从归一化峰值电磁场和分路阻抗两方面出发，比较了横截面为横向跑道和纵向跑道的Spoke 基部。Spoke 基部横截面的形状为横向跑道时能得到较好的射频参数，满足中国ADS(C-ADS) 的工程需求。最后利用CST 粒子工作室对得到的腔体进行了二次电子倍增分析，在工作电压附近不存在二次电子倍增，验证了该腔体形状的可行性。The EM design of a 325 MHz β= 0.52 superconducting double Spoke cavity has been finished at Institute of Modern Physics (IMP), Chinese Academy of Sciences(CAS). In this paper, the optimization of the Spoke base is described in detail. The goal is to minimize the peak surface field and maximize the shunt impedance. The common cylinder is replaced by the racetrack shape for the Spoke base. The transverse racetrack Spoke base can offer a better RF property than the longitudinal racetrack Spoke base, which meet the requirement of the C-ADS. The simulation of multipactor finished by CST Particle Studio is also presented, which gives a promising result that there is no multipactor around working voltage.
