Abstract
PURPOSE: To enable independent control of frame astigmation of horizontal and vertical field of deflector to a certain extent, by employing a controller comprised of a circular board and tubular member.
CONSTITUTION: Convergence electrode 41 is provided at the beam discharging side of electron gun 40 while a deflecting device 42 is provided in said electrode 41 or in the advancing direction of beam, while furthermore a rear field 43 and a controller 44 made of magnetic member are provided in electron beam passing region between the deflecting device 42 and the convergence electrode 41. The controller 44 is formed with a circular board and tubular member.
