摘　　要：通过设计并运用一种直流电子束轨迹简易测量方法,开展了永磁约束电子束轨迹实验研究,得到了永磁铁环对60~80 ke V电子束约束作用的实验数据。结果表明:该测量方法方便有效,结果较为准确;永磁铁对电子束聚焦作用明显,并呈现出一定的规律性。对永磁铁约束电子束研究工作奠定了基础。A simple measurement method of DC electron beam trajectory was designed. With this measurement method, some experimental studies of trajectory of electron beam confined by permanent magnet （PM） were researched. Some experiment data of PM ring which can restrain the electron beam at 60-80 keV were gotten. The results show that the measurement method is convenient and effective, the results are comparatively accurate, PM have an evident focusing effect on electron beam, and this effect has a certain regularity. It laid a foundation for future farther study on magnetically-confined electron beam by means of permanent magnets.
