Abstract

482,026. Electron multipliers. FARNSWORTH TELEVISION, Inc. May 26, 1937, No. 14587. Convention date, June 1, 1936. [Class 39 (i)] A multiplier has alternately cylindrical and plane secondary cathodes. As shown, short cylindrical members 11, 12, 14 alternate with discs 17, 19, 24 of increasing diameter the last of which is the output electrode. The current from the primary cathode 9 is controlled by a grid 10. The first secondary cathode and the output electrode may be either discs or cylinders. The secondary emitting surfaces may be thin films of thorium, or caesium, or potassium, or calcium.
