Abstract
In a color picture tube, aberration is an important factor influencing the electron beam spot on the screen. This paper discusses a new meth od which is used to calculate the aberration of an electron gun in a C PT. In this method, electron trajectories are simulated directly in th e cathode and the pre-focus lens. In the main lens, the asymptotic abe rration is calculated to decide the size of the image. Some results of the calculation are shown in this paper.
