借助三维静磁场分析软件,模拟仿真了两种非旋转对称PPM聚焦系统的内部磁场：极靴耦合槽分别呈180°和0°排列。根据仿真结果分析了阿良莫夫斯基关于PPM聚焦系统磁场实验中的横向磁场成因;总结了铁制加载头对PPM聚焦系统横向磁场的改善效果以及对磁饱和的影响。最后归纳出横向磁场的3种成因,分别阐述了铁制加载头对其影响;给出了耦合槽呈180°和0°排列两种情况下横向磁场的改善方法。

The internal magnetic fields of two asymmetric PPM focusing systems are simulated with 3D magnetic fields software in this paper.One of them,the coupling slot is arranged with 180,and another arranged in a line.Based on the results,we analyses the transverse magnetic fields of asymmetric PPM focusing systems and the reasons of the transverse magnetic fields in the two structures.The improved efficiency and magnetic saturation to asymmetric PPM focusing systems by adjusting the iron loading head are summarized.Finally,three different reasons of the transverse magnetic fields and the improved methods reducing the transverse magnetic fields of the two structures are presented.
