摘　　要：为了减少目前SFC轴向注入系统中聚束器杂散电场对束流轴向注入效率的影响,提高新系统中SFC的束流俘获效率,参考原始设计,对目前聚束器的电极结构进行了设计改进．两种情况下的聚束器杂散场对注入效率影响的计算表明,改进后0802的聚束效率较目前有较大提高．同时计算了束流空间电荷效应对聚束效率的影响,据此对新SFC轴向注入系统中聚束器的位置进行了重新调整．In order to reduce the influence of the stray electric field of the buncher in the axial injection system of SFC and to improve the injection efficiency of SFC, the existing buncher electrode is investigated and a new electrode is designed. The influences of the electric field to the beams for the both cases are simulated. The simulation results show that the bunching efficiency is improved from 55% to 74% with the new electrode. At the same time, the influence of the space charge is computed and according to the results, the location of the buncher is readjusted too.
