Abstract

532,025. Electron multipliers. BOSCH, F. J. G. VAN DEN, and VACUUM-SCIENCE PRODUCTS, Ltd. June 12, 1939, No. 17172. [Class 39 (i)] To arrest secondary electrons emitted from the accelerating anode of an electron-multiplier a second anode is arranged between the first and the cathode. The Figure shows an annular accelera. ting anode 13 and an annular arresting anode 16, the apertures of the anode 16 being greater than that of the anode 13. The twc anodes are in electric connection The invention is shown in connection with an electron-multiplier such as that described in Specification 516,621 with grids in front of the secondary electrodes.
