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 .
The improvement of accelerating voltage of SSC is of great significance for the improvement of the overall operation of HIRFL.Using three-dimensional electromagnetic field calculation program MAFIA to make a more detailed analysis of the SSC high frequency cavity, recalculating the main parameters of the cavity, As a result, the feasibility of voltage increase is analyzed preliminarily. Because a small amount of power loss may affect the stability of the cavity-machine system under high power operation, at the same time, by using the results of MAFIA calculation, the power coupling system Re-analysis, get the theoretical value of power reflection and improve the program.
