摘要
文章给出了北京正负电子对撞机二期工程(BEPCⅡ)未来预注入器中571.2 MHz次谐波聚束腔结构的物理设计步骤和方法。分别使用二维有限差分法分析软件Superfish和三维有限积分法分析软件MAFIA对优化后的聚束腔结构进行了计算,得到了比较一致的结果。另外,对Superfish和MAFIA在设计聚束腔结构上的优缺点进行了比较。
The paper concerns in the physical design method of 571. 2 MHz subharmonic buncher. The two dimensional finite difference method software-Superfish and the three dimensional finite integration method software-MAFIA were used to simulate the structure of the sub-harmonic buncher. Both of the simulation results are in good consistency with the design data. In addition, the characteristics in the RF cavity simulation with the two softwares are compared.
