ABSTRACT:
The novel CRT has an electron gun mount assembly therein which is similar in construction to prior CRT's. The electron gun mount assembly includes a cathode for generating at least one electron beam and a plurality of successively spaced electrodes including a screen grid electrode, a focusing electrode and an anode electrode secured to one major surface of at least two longitudinally extending insulating support beads. A first gap of predetermined width extends between the anode electrode and one end of the focusing electrode. A second gap of predetermined width extends between the opposite end of the focusing electrode and the screen grid electrode. An opposite major surface of each of the support beads faces outwardly and has thereon an electrically-conducting coating having a longitudinal dimension, d. Suitable voltages are applied to the electrodes to generate electrical activity. The coating on each of the beads is spaced a distance 1.25.times.d from the end of the focusing electrode adjacent to the second gap.
