FEM模型及三层厚隔膜的Fourier分解
FEM models and Fourier decomposition of three thick septa
摘要：
CEBAF再循环直线加速器使用26个隔膜：8个薄隔膜、17个厚隔膜和1个Lambertson隔膜。我们在这里报告详细的有限元模型的一个厚的电流片隔膜，Lambertson，和一个新的厚隔膜的概念，其中包含的功能。最后一个具有高阶场分量，在电流片隔膜的两倍内，并且导体中的电流密度低得多，其被用作CEBAF中的插入式替换。有加速器布局，其中新概念在谐波含量和电流密度方面都优于当前的片状隔膜。
英文摘要：
The CEBAF recirculating linear accelerator uses 26 septa: 8 thin, 17 thick and one Lambertson. We report here on detailed FEM models of one thick current-sheet septum, the Lambertson, and a new thick-septum concept which contains features of both. The last has higher-order field components within a factor of two of the current-sheet septum and much lower current density in the conductor were it used as a drop-in replacement in CEBAF. There are accelerator layouts in which the new concept is superior to the current sheet septum in both harmonic content and current density.
