| 摘 要： | 本文对四极磁透镜的磁场分布和电子的输运问题进行了研究和计算。文中阐述了四极磁透镜边缘场的三种处理方法,用这三种方法计算了透镜的输运矩阵。相互比较表明,四极磁透镜的边缘场采用传统的直角边近似就可以很好地解决问题。

| Abstract: | Field properties of magnetic quadrupole lenses and electron beam transport are studied in this paper. To calculate the transfer matrix in the fringe region of a quadrupole lens, three kinds of methods are used. According to the calculated results, it is shown that the result of the hard-edged model is in good agreement with that of numerical calculation. |
