强流射频四极加速器耦合单元的物理设计研究
Computer simulation study on the design of the coupling cell in an RFQ with intense beams
摘要
用二维程序SUPERFISH 和三维程序MAFIA对射频四极加速器进行了计算机模拟.通过模拟,确定了射频四极加速器中工作模的射频电场的分布, 完成了射频四极加速器的耦合单元、调谐块和起始单元的设计.设计耦合单元必须使射频四极加速对干扰不敏感.对设计的方案进行了讨论和分析.
Abstract
Computer simulations are carried out for an RFQ in either 2-D coordinates (by SUPERFISH) or 3-D coordinates (by MAFIA), by which the RF field distribution of the operating mode is determined and the designing on the coupling cell is made. In the meantime, the tuners and the beginning cell of RFQ are also designed. The designing on the coupling cell must satisfy the condition that the RFQ is most insensitive to perturbations. To this end, the mode spacing of the two neighbour modes of the operating mode with respect to operating mode are chosen to be equal.
