摘要
合肥 8 0 0MeV电子储存环的二期升级工程正在进行 ,其中高频腔的改造和加工将要完成 ,由于原有高频腔存在较多不合理因数 ,将要被新腔所替换。为了充分估计在将来运行时 ,高频腔的耦合阻抗对储存高流强的影响 ,需要对新旧高频腔宽带耦合阻抗进行比较计算。用电磁场计算软件MAFIA对高频腔的耦合阻抗及电子束在此结构中产生的尾场进行了计算 ,结果说明旧高频腔的耦合阻抗比新高频腔小。
The phase II upgrading project of Hefei 800 MeV electron storage ring is being done, and the important component of the project, the RF cavity, will be finished soon. The old RF cavity with many disadvantages will be replaced by the new one. To estimate the effect of RF cavity coupling impedance to storing bunch intensity fully, the wake potential and the broad band couple impedance of RF cavity were calculated with MAFIA program. And the calculation results were compared between new and old cavity, it is found that the impedance of the new is bigger than that of the old.
