| 摘 要： | 本文由曲线坐标系下的相对论修正普遍轨迹方程出发,考虑包含阴极物面的宽电子束聚焦的情况,推导了曲线坐标系下的主轨迹方程与曲近轴轨迹方程,研究了满足正交条件的近轴系统的特性。曲线坐标系下的细电子束聚焦问题以及非相对论修正的宽电子束聚焦问题均可视为本文的特例。

| Abstract: | Based on the relativistic general trajectory equations solved by the tensor method in a Frenet lecal coordinate system, considering the characteristics of wide electron beam focusing possessing a cathode surface, equations of the principal trajectory and the curvilinear "paraxial" trajectory are deduced. The characteristics of the curvilinear "paraxial" system satisfying the orthogonal condition are studied. Problems concerning narrow electron beam focusing or non-relativistic wide electron beam focusing in a curvilinear coordinate system can be regarded as special cases thereof. |
