ABSTRACT:
By application of a predetermined period of relatively higher magnitude of electron beam emission from the cathode of the electron gun to the anode maintained at high voltage the potential gradient on the inside of the neck portion of a cathode ray tube is stabilized and the phenomenon of electron beam drift is thus suppressed effectively.
