摘要
利用电子束实验仪进行电子荷质比测定的磁聚焦实验原理,通过对同一实验多组实验数据的分析处理,提出了磁聚焦法测荷质比实验电子束螺旋线起点位置的方法.
Introduced the use of electron-beam experiment for the determination of electronic charge-mass ratio of the magnetic focusing experiment principle. Through analysising the same groups of experimental data, proposed magnetic focusing method experimental charge-mass ratio of electron beam cross-point location of the initial determination.
