Abstract

PURPOSE: To prevent an increase in diameter and deformation of the beam spot by providing a method, which is able to control independently longitudinal and lateral scattering angles of beams corresponding to the variations of the deflection angle of electron beams, between the 2nd grid electrode and 3rd grid electrode of the electron gun.
