双向聚焦电磁铁摇摆器磁场的数值模拟
-
摘要: 应用磁矢量势公式导出了螺线圈绕组的磁场计算公式,应用标量磁势并对电磁铁作局部均匀磁化近似,给出了电磁铁摇摆器磁场的积分方程式和相应的耦合系数。通过求解积分方程得到了摇摆器磁场的空间分布及摇摆器两端非均匀区的磁场分布。本方法可以为双向聚焦电磁铁摇摆器的设计提供参考数据。Abstract: A 3-D simulation code are developed for the x,y double-direction focusing electromagnet wiggler by integration equation method, and some simulated results for a high gain electromagnet wiggler is shown.
