Abstract
518,553. Electron multipliers. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and BANKS, G. B. Aug. 26, 1938, No. 25173. Addition to 511,449. [Class 39 (i)] In a multiplier the secondary emissive electrode 4 is " out of sight " of the barium coated cathode 1 the electrons being deflected by electrostatic means ; either the plate 8 or a coating on the envelope is used. The anode 6 is of grid form and with a second grid 5 forms a lens to direct the primary electrons on the electrode 4. A plate 7 shields the cathode from direct access to the electrode 4 ; the cathode is end on to the latter and the grid supports 2 assists in the shielding.
