Abstract

PURPOSE: To permit ready manufacture and maintenance control by forming an end plate of a focusing electrode on the side of an accelerating electrode with non-circular opposite side electron beam holes such that the actual center thereof is deviated with respect to the axis of the respective opposite side electron beams formed in the accelerating electrode.
CONSTITUTION: Of three electron beam holes g33, g33' and g33" formed in an end plate G33 of a focusing electrode on the side of an accelerating electrode the opposite side holes g33' and g33" have a horizontally oval form, with their outer centers C1' and C1" respectively aligned to the axes a2' and a2" of opposite side electron beam holes g2' and g2" of the accelerating electrode G2. Thus, the actual centers of the holes g33' and g33" are in inwardly deviated positions with respect to the axes a2' and a2" of opposite side electron beam holes g2' and g2" of the accelerating electrode G2.
