Abstract

1,127,382. Electron beam apparatus; electron multipliers. BENDIX CORP. 1 Dec., 1965 [7 Dec., 1964], No. 10215/67. Divided out of 1,127,381. Heading H1D. An electron accelerating device comprises an insulating tube 50 provided with an internal or an external resistive coating 52 across which a voltage is applied, the radial thickness of the coating decreasing down the tube thus providing an increasing resistivity to current flow such that there is established a longitudinal potential gradient which changes as a function of axial displacement and creates an electrostatic accelerating field having a longitudinal component and a radial component directing the electrons towards the central axis of the channel. The longitudinal potential gradient may increase linearly with distance or at a lesser or greater rate while the radial potential gradient may be constant or increase or decrease linearly. The tube 50 may be of glass and the resistive coating of a predominantly tin, antimony or lead oxide composition. A number of tubes 50 may be bonded together to form a mosaic structure for use in an image intensifier tube, the fluorescent screen being mounted in electrical contact with the end of the mosaic structure. In electron multiplier structures the, or each, insulating tube is provided with an initial section of uniform resistivity where electron multiplication takes place.
