An electron gun code is used to simulate the electrontrajectory, the influence of electrode shape, magnet field, electrontrajectory on the electron beam have been studied.
The cathode of the gun may be partially shielded magnetically. The paraxial-ray equation for describing the electrontrajectory in the accelerating region is solved in closed form.
