Abstract
728,932. Velocity-modulated tubes. RAYTHEON MANUFACTURING CO. Nov. 11, 1952 [April 8, 1952], No. 28442/52. Class 39 (1). The repeller electrode in a retarding field oscillator tube is constructed at its end nearer the accelerating anode to provide an electrical field which can return to the outer surface of the accelerating anode those electrons which penetrate furthest into the repeller electrode. The tube shown comprises a hollow spheroid cathode 11 heated by a coil 12 and emitting electrons through an anode in the form of a conical member 13 forming part of the wall of a resonant cavity 14 into a hollow cylindrical repeller electrode 15 comprising a tube of insulating material coated inside and outside with conductive material. The tube 15 is mounted so as to be electrically isolated for direct current from the wall of the opening 18 in the cavity 14 but coupled capacitively to the cavity at radio frequency through a virtual short-circuit. Tuning is effected by moving the repeller tube 15 relative to the anode 13 by means of a rod 20 passing through the envelope 10 by way of a bellows 21 which permits the rod 20 to be moved in either of the directions indicated by the arrows 22 and 23. A rod 24 of conductive material is mounted inside the tube 15 and is provided with a terminal 26 for connection to a source of potential which for tuning purposes may be different from that of the tube 15, in which case the rod 24 must be suitably insulated from the tube 15. A spike 25 formed at the end of the rod 24 distorts the repelling field so that those electrons which penetrate furthest into the repeller tube 15 are returned to the outer surface of the anode 13. In an alternative arrangement the repeller electrode is a hollow conductive cylinder and is provided with openings near the end of the wall of the cylinder near the anode to distort the repelling field. The openings may be slots in the wall or may be provided by connecting a short section of tube to the main electrode by a plurality of rods lying in the cylindrical surface of the tube.
