Abstract

This paper includes finding a mathematical relationship between the distance from the emitter to the width of the Wehnelt cylinder bore and the diameter of that bore, by studying the effect and correlation of these two parameters on the quality of the electron beam. A group of electron guns with identical and variable geometric parameters were designed for the values of the Wehnelt cylinder aperture radius for each case from the emitter site, which represents the distance from the emitter head to the Wehnelt cylinder aperture. As well as the calculation of the electron beam diameter and the brightness and emittance, as the mathematical relationship between these two parameters was found to be linear.
热离子电子枪发射极位置与Wehnelt圆柱孔径半径的关系
本文通过研究从发射极到Wehnelt筒腔宽度的距离和筒腔直径这两个参数对电子束质量的影响和相互关系,找到了两者之间的数学关系。设计了一组几何参数相同、几何参数可变的电子枪,每一种情况下的Wehnelt圆柱孔径半径值代表了从发射器头部到Wehnelt圆柱孔径的距离。并计算了电子束直径、亮度和发射度,发现这两个参数之间的数学关系是线性的。
