Abstract
An ellipse-shaped electron gun designed for sheet beam devices is presented. At present, two different focus electrodes have been respectively studied by using the CST simulation. It is found that the electron gun with a rectangle-shaped focus electrode can produce greater beam current, higher aspect ratio, and better laminarity than that with an ellipse-shaped one.
