文章以7注耦合腔行波管为例，分析了多注PPM （周期永磁）聚焦系统中横向磁场的产生位置和各处横向磁场的产生原因；总结了耦合槽、铁制加载头高度和通道孔所在半径对各处横向磁场的影响；针对各处横向磁场的产生原因，给出了可以从根本上改善横向磁场的方法，利用此方法设计的多注 PPM 聚焦系统的横向磁场与轴向磁场之比可达0.6％，电子通过率可达98％。

T he position and causes of the transverse magnetic fields of multi-beam periodic permanent magnet (PPM) focusing system are analyzed via the 7-beam coupled cavity traveling wave tube .The effect of the cou-pling slot ,the height of iron loading head and the radius of the channel holes on the transverse magnetic fields is summarized .The method to fundamentally improve the transverse magnetic field is proposed according to the causes of the transverse magnetic fields .With this method ,the ratio of transverse magnetic field to axial magnetic field can reach 0.6% ,and the electron transfer rate is up to 98% .
