ABSTRACT:
A charged-particle beam tube having an envelope of a dielectric material and a pattern yoke formed on the inner surface of the envelope. The pattern yoke has a pair of horizonal deflection electrodes and a pair of vertical deflection electrodes arranged alternately. The horizontal deflection electrodes have a greater circumferential width than the vertical deflection electrodes. The horizontal and vertical deflection electrodes are supplied with different bias voltages.
