摘　　要：SSC加速电压的提高对于HIRFL整体运行水平的提高具有重要的意义 .利用三维电磁场计算程序MAFIA对SSC高频腔体作了更为细致的分析 ,重新计算了腔体的主要参数 ,结合运行中的实际结果 ,对电压提高的可行性进行了初步分析 ;由于在大功率运行状态下 ,少量的功率损失都可能影响腔 -机系统的稳定性 ,所以同时利用MAFIA计算得到的结果 ,对功率耦合系统重新做了分析 ,得到了功率反射的理论极值及改进方案 .It is important for HIRFL to improve the whole operation level if SSC accelerating voltage can be increased. In order to increase the voltage, it should firstly analyze the maximum voltage that SSC RF cavity can achieve in theory. SSC RF cavity was thoroughly analyzed and the main parameters of the cavity were obtained by using a three-dimensional electromagnetic calculation code. Based on the simulation results and the practical operation parameters the possibility of increasing the voltage is discussed. Since the little power loss in high-power operation may affect the stability of the cavity-amplifier system, the power coupling system was also analyzed. The limit of power reflection is got and the improving methods are discussed too.
