Abstract
592,348. Electron discharge apparatus. RAYTHEON MANUFACTURING CO. April 28, 1944, No. 8056. Convention date, Dec. 1, 1941. [Class 39 (i)] In an electron discharge device comprising an anode structure including a plurality of anode arms, each pair of arms constituting with the intermediate portion of the anode structure a resonant circuit, low impedance means are provided for maintaining alternate anode arms substantially equipotential so as to avoid oscillation in undesired modes. The apparatus shown consists of a magnetron in which the anode block 4 is formed with cylindrical resonance cavities 14 communicating by slots 13 between adjacent arms 24, 25, &c. with a central space surrounding the cathode 6. Alternate arms 24, 26, &c. are connected by a copper ring 32 at the upper end of the block, the remaining arms 25, 27, &c. being cut away to avoid contact with the ring ; the arms 25, 27, &c. are similarly connected by a ring at the lower end of the block. Energy is withdrawn by a loop 17 fastened to the wall of one cavity and connected to a wire 18 passing through a glass seal 19 on a tube 20. A concentric conductor may be mounted on the tube 20. The block 4 is axially extended at the outside 1 to form upper and lower spaces closed by flat members the spaces enclosing cathode leads 8 which emerge through glass seals 10 on exit pipes 12 ; the cathode is indirectly heated. A getter such as barium may be provided in a glass bulb 22 connected to one of the end spaces by a tube 21 and may be vaporized by heating externally or by magnetic induction. The apparatus is mounted between the poles of a magnet.
