ABSTRACT:
A CRT comprising an evacuated envelope having an electrically-insulating neck and a beaded electron-gun mount assembly in the neck. Portions of the surfaces of the beads facing the inner surface of the neck carry electrically-conducting coatings for suppressing arcing during the operation of the tube. The coatings and the claws of the electrodes embedded in the beads are positioned to minimize erosion of the patches during electrical processing of the electrodes.
