Abstract
979,687. Electron multipliers. BENDIX CORPORATION. March 26, 1963 [April 13, 1962], No. 11815/63. Drawings to Specification. Heading H1D. An electron multiplier comprises a tube with a secondary emissive, resistive, coating along which a P.D. is applied to produce a transverse electric field inclined to the axis, so that the electrons " hop " along the secondary emitter. The inclined field may be produced by inclining the ends of the tube, Fig. 1 (not shown), or forming an inclined conductive end coating inside the tube, Fig, 5 (not shown). The ends of the tube may not be parallel to produce a varying inclination along the tube and thereby reduce " noise," Fig. 4 (not shown). Alternatively a pair of parallel plates may be used coated with a resistive emitter, Fig. 6 (not shown); or a series of parallel multiplier tubes may be used with a photo-cathode and screen to form an image converter, Fig. 3 (not shown). Specifications 954,248, 965,044 and 971,773 are referred to.
