Abstract: A sequential device for two perpendicular sets of conductive strips employed with a channel-type electron multiplier to allow only one hole through the multiplier to accept and emit electrons at a time. The device may utilize an electron gun for each set of strips to provide an electron beam to scan each set simply by use of a sawtooth deflection voltage. An effective raster-type scan of the multiplier may thus be accomplished. The device is an improvement because arrangements requiring counters or staircase generators are much more expensive.

Abstract: A flat panel cathode ray display in which a phosphor screen is selectively excited from an area cathode through a multichannel flat panel electron multiplier array. Electrons are permitted to flow substantially only through one hole of the multichannel array at a time as controlled by separate radial and circumferential scan components. The holes of the multichannel array are arranged in substantially concentric circles and also in radial lines, and a system of conductive strips provides a gating potential distribution means to effect sequencing of the required pattern of electron flow through the multichannel array holes. The aforementioned holes are through the bottom of a panshaped insulating body, the extensions of the radial and circular conductive strips overlapping the holes being drawn up over the insides of the pan-shaped body side flanges or walls. Separate electron beam scanning means for the conductive extensions of the circular and radial strips are provided by electron beam scanning means around selected portions of the inside surface of the side flange. Secondary emissive material on the individual conductive extensions provides a switching or gating effect during scanning electron beam impingement.
