ABSTRACT:
An evacuated envelope includes front and back walls and a plurality of spaced, parallel supports between, and perpendicular thereto which form a plurality of parallel channels. A gun structure at one end of the channels directs one or more electron beams along each of the channels. In each of the channels is at least one beam guide which confines the electrons of the beam but permits selective deflection of the electron beam out of the guide toward a phosphor screen on the inner surface of the front wall. The beam guide includes electrodes on the inner surface of the back wall and either a single grid plate or a pair of spaced, parallel grid plates spaced from and parallel to the back wall. The beam guide also includes means for laterally confining the electrons of the beam which may include spaced parallel wires between the back wall and the grid plates and extending along the channel or a special configuration of the electrodes on the back wall.
