摘要

本文建立了具有非轴对称复合静电磁场结构的电子枪中具有横向热初速分布的三维曲线细电子束的空间电荷理论。作为本理论的应用

在无热初速零散的卡诺平面空间电荷流基础上

对卡诺长枪中一仅考虑横向麦氏初速分布的“热”细电子束的空间电荷密度作了数值计算。

Abstract

In this paper the space charge theory for a three-dimensional curvilinear beam-let with transversal initial velocity spread in electron guns composed of non-axisymmetric electron-optical systems is established.As a simple example of application

based on Kino’s plane space charge fluid theory

the space charge density of some three-dimensional curvilinear beamlet with transversal Maxwell initial velocity spread in a long Kino’ sgun is numerically calculated.
