Title: Electron discharge device using secondary emission for density modulation of an electronic beam
IPC: H01J25/10
Filed: 1947-05-07
Abstract: 645,837. Velocity-modulated tubes. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. May 7, 1947, No. 12396. Convention date, May 7, 1946. [Class 39 (i)] A velocity modulated beam of electrons is passed through a preferably constant electric and/or magnetic deflecting field before impinging on a secondary emissive target P. Since the deflection varies with the electron velocity the beam is caused to sweep over the target P of which the secondary emissivity varies from point to point so that the secondary beam is density modulated. The target P may be wholly covered by a number of layers of different secondary emissivity or alternatively only certain discrete areas spaced from one another by relatively non-emissive areas may be covered with secondary emissive material of the same secondary emissivity or a combination of both expedients may be used. A buncher AB and deflecting plates D, D<SP>1</SP> are shown ; the target P is concave and the bunched secondary beam excites catcher C. The primary beam is preferably flat, i.e. it has a small dimension parallel to the direction of deflection and a wide dimension at right angles to the first dimension, the secondary emissive layers being correspondingly shaped. The device may be used as a frequency multiplier. The catcher C may be a cavity resonator. The impedance of the secondary beam may be matched to the impedance of the catcher C.
