Abstract

Beam adjustment apparatus for converging a plurality of spaced apart coplanar electron beams of a cathode ray tube, characterized by a first assembly (25) adapted to be adjustable rotatably mounted around the neck region of said tube, said first assembly (25) including at least one set (25b) of a plurality of equally circumferentially spaced permanent magnets (27), all magnets of a set having like poles (N) disposed toward the center of said neck region for producing opposite direction motion of substantially only the outside ones of said beams; and a second assembly (24) adapted to be adjustably rotatably mounted around the neck region of said tube, said second assembly (24) including at least one set (24a) of a plurality of equally circumferentially spaced permanent magnets (27), ail magnets of a set having like poles (S) disposed toward the center of 3aid neck region for producing the same direction motion of substantially only ths outside ones of said beams.
