摘要:
双梁结构超导偏转腔可对带电粒子束进行快速的偏转或旋转,具有紧凑、高效的特性,在超导自由电子激光、高能粒子对撞机等加速器装置中具有广泛的应用前景。该类型超导腔设计研究的一个重点是双梁形状的选择和尺寸的优化。针对中国科学院高能物理研究所提议建设的、基于超导直线加速器的 X 射线自由电子激光装置,采用 CST MWS,CST PS,COMSOL,ANSYS 等软件仿真手段,结合理论分析,完成了一款双梁形状为梯形的超导偏转腔的优化设计。该梯形双梁结构偏转腔具有良好的电磁和机械性能,同时,腔的尺寸更加紧凑,加工难度也有所降低。
Abstract:
Superconducting parallel-bar deflectors are deflecting/crabbing cavities with attractive properties,such as com-pact structure and high efficiency.Aiming at the application in the XFEL proposed by Institute of High Energy Physics,a 325 MHz superconducting deflector with trapezoid parallel-bars is investigated and optimized.This paper presents the details on the design method and results of this deflector as follows:the simulation codes of CST MWS,CST PS,COMSOL,ANSYS are em-ployed,the electromagnetic and mechanical parameters of the deflector are competitive,and the machining process is improved.
