六层加侧混合型摇摆器磁场的理论计算与数值模拟
-
摘要: 利用文献[1，2]给出的结果，提供了六层加侧混合型摇摆器中永磁体磁场的计算公式和软铁磁场计算的积分方程式。对周期长度lw =1.6cm，磁极间隙g=0.5cm的情况，计算了单向聚焦和双向聚焦两种不同构形的磁场分布，并得到了g /lw =1/3条件下，峰值磁场Bw超过1特斯拉的设计指标。Abstract: In this paper, we suggest a new hybrid wiggles with six lagers and side –blocks which has two direction focusing function, and simulate the magnetic field of the new hybrid wiggles. Under the limitation g/l w =3, the peak magnetic field of new hybrid wiggles is in excess of 1T.
