Abstract
537,276. Electron multipliers. STANDARD TELEPHONES & CABLES, Ltd. Dec. 22, 1939, No. 32813. Convention date, Dec. 29, 1938. [Class 39 (i)] In an electron multiplier a magnetic control field H is parallel with the direction of emission from the thermionic cathode 1; the flow is past a control grid 2 and screen grid 3 on to an electrode 4 which is either biased to act as a reflector or is the first secondary emission electrode. In a modification with a horizontal field, Fig. 5, the cathode is arranged to give two streams in line with the field. A screen 13, Fig. 7, at cathode potential prevents return of secondaries towards the cathode.
