Abstract

950,640. Electron multipliers. BENDIX CORPORATION. April 21, 1961, No. 14584/61. Heading H1D. An electron multiplier is formed with a continuous channel bounded by a secondarily-emissive surface 16, and having a length to width ratio at least equal to 10, situated between a source 22 of primary particles and a collector 18. Different voltages are applied to the opposite ends of surface 16 to create a longitudinal accelerating field within the channel. The particles are caused to strike surface 16 by the exclusive effect of the random initial velocity components of the primary particles without application of any transverse accelerating field. As shown, a glass tube 10 coated internally with a secondary-electronemissive, resistive material such as a tin oxide or a carbon compound is disposed between a photo-cathode 18 and an anode 22, potentials of - 1700, - 1500, +1500 and +1700 volts being applied to the cathode, the ends of the dynode and the anode, respectively. A plurality of tubular dynodes of narrow cross-section may be secured together in side-by-side relation between a photo-cathode and a fluorescent screen in an image intensifier tube, Fig. 4 (not shown). The light intensifier tube shown in Fig. 6, comprises a wafer 100, 0.012 inch thick, of secondaryemissive glass having a resistivity of 10<SP>-11</SP>ohm cm., and provided with perforations 0.001 inch in diameter, arranged between a photo-cathode 106 and a fluorescent screen 108. The wafer has silver coatings 104 on each side to which accelerating potentials are applied. In further embodiments of the invention, the facing surfaces of two flat, parallel plates or of two concentric cylinders are coated with secondaryemissive, resistive material to provide a multiplying region between a cathode and anode, Figs. 7 and 8 (not shown), and in the latter case the cathode may be annular. By use of secondary-emissive material which is also photoemissive, the cathode may be dispensed with, light being focused directly into the tube 10, Fig. 3.
