Numerical study for the effect of angle between inner wall of Wehnelt electrode and its axis on beam dynamics in a thermionic electron gun
Welding electron guns are usually designed using the theory of electron optics, where a change in the size of the Wehnelt electrode in the electrostatic field causes variations in the motion behavior of the electron beam. In this study, the COMSOL software is used to carry out finite element simulat...
