摘要
本文导出了用积分方程法计算三维混合型磁铁（永磁铁和软铁的组合体）磁场强度的方程组，以及磁体计算网格为长方体时的耦合系数，相应地编制了数值计算程序。给出了软铁的磁化强度与永磁铁布局关系的数值模拟结果。最后对一种实验型高效微型混合磁铁摇摆器进行了数值计算。
AbstractIn the hybrid wiggler,permanent magnets are used in conjunction the steel blocks to producelarged field amplitudes than Halbach wiggler.We suggest a new hybrid design shown in Fig.1.Theblocks,with arrow are peimanent magnets and the blocks without arrow are steel blocks.In ourdesign,the new idea is that the steel blocks are used in conjunction permanent magnets in the side(the V_2,V_3,V_6 and V_7 blocks in Fig.1).We hope the new idea will further increase the fieldamplitudes.In order to demonstrate our idea,we have been develo ped 3-dimensionalional code of the hybridwiggler magnetic fields on integrated equations,and have been given simulating results of a hybridnlicro-wiggler with side-blocks(see table 2 and Fig.4,6).The results are shown that the fieldamplitudes with side-blocks wiggler are more 25 % than the field amplitudes without s ide-blocks.
