144 MHz Niobium Sputtered Superconducting Cavity Physical Design for HI-13 Tandem Upgrade Project
【摘要】 为设计HI-13串列加速器升级工程中的QWR铜铌溅射超导腔,利用电磁场计算软件和力学结构计算软件分析了QWR腔的高频特性和机械振动频率。考虑到QWR腔在加工和运行时的环境温度差异,给出了QWR腔常温加工时的几何尺寸。本工作还分析了QWR腔电磁场的不对称性对束流输运的影响。
【Abstract】 In order to design the niobium sputtered superconducting cavity used in HI-13 tandem upgrade project,RF performance and mechanical frequency of QWR cavity is analyzed by numerical simulation.Considered the difference of cavity body temperatures in manufacture case and online case,geometry of cavity in room temperature environ- ment is given.Affection of asymmetrical electromagnetic field of QWR cavity to beam transfer is also analyzed in the paper.
