Abstract

598,791. Electron multipliers. M-O VALVE CO., Ltd., and WARREN, G. W. Sept. 10, 1945, No. 23282. [Class 39(i)] An electron multiplier comprises within a sealed envelope an anode, a primary thermionic cathode and one or more secondary cathodes which form part of, or are electrically connected to, metal plates sealed through the envelope. The secondary cathodes may be in the form of plane grids covering apertures in the metal plates, or as shown in Fig. 2 are constituted by cylindrical skirts 14, 15, 16 secured to plates 18, 19, 20. Cylindrical accelerator grids 21 are connected to the anode 12 and the secondary cathodes, and arranged within the preceding cathodes. One or more control grids 13 may also be provided.
