FLAT ELECTRON BEAM ADDRESSED DEVICE . Abstract An evacuated envelope has a rectangular addressing section and a gun section at one edge of the addressing section. The addressing section includes front and back walls in closely spaced, parallel relation, and a plurality of spaced, parallel support walls between the front and back walls forming a plurality of parallel channels. The gun section extends across one end of the channels and includes gun structure which will selectively direct electrons along each of the channels. In each of the channels are electrostatic guides to confine the electrons in a beam which is spaced from the walls of the channel and also guide the beam along the length of the channel. Electrostatic deflection permits selective deflection of the electron beams toward a target, e.g., a phosphor screen, which is disposed along the inner surface of the front wall. -1-
