摘要： An anode structure for a magnetron includes T-shape anode vanes having a radially extensive component and a circumferentially extensive portion, the cylindrical faces of the circumferential portion facing a cathode in the complete magnetron. The use of T-shape vanes increases inductance and hence permits low frequency radiation to be generated without increasing the dimensions of the magnetron compared to those of a conventional magnetron. Also, capacitance is increased to give a further reduction in frequency by using more than two anode straps, and preferably four anode straps at each end of the anode structure. Preferably, the anode structure is incorporated in a magnetron in which a high magnetic field of the order of 500 Gauss for a magnetron operating at 100 MHZ is used. The anode shell itself may form part of the magnetic return path. Other anode vane configuration, for example L-shaped, may be used.

摘要： A collector for a linear beam has a segmented ceramic collector core that permits sustained operation at high temperatures and power densities. The collector provides efficient heat transfer from the while reducing stresses on collector components caused by thermal cycling and comprises a heat sink having a cavity providing interior vacuum walls for the collector a segmented ceramic insulator disposed inside the cavity, and an electrode disposed inside and against the insulator. The insulator comprises sectors separated from one another by gaps, and may be notched in its outer surface for high-voltage stand-off from the sink. The electrode is preferably not brazed/soldered to the insulator. A stage of the electrode may be probeless and comprise a depression. A molybdenum-fabricated heat sink and stage assembly utilizes an insulator constructed from beryllium oxide, aluminum nitride, or alumina; alternatively, a copper assembly, uses an aluminum nitride insulator.

摘要： A collector core of a microwave tube has an insulator and a radiator around a cylindrical outer peripheral portion thereof. The cylindrical insulator and radiator comprise a slit along a central axis of the collector core, respectively. These slits are arranged on mutually overlapped positions. Portions of the collector core corresponding to these slits are cut off so as to be flat or concave. These slits and the flat surface or the concave portion are arranged symmetrically in a section of the collector core.

摘要： An inductive output tube (IOT) of a multi-staged depressed collector provides improved efficiency by approximating a Brillouin electron beam flow. In one embodiment, an IOT is provided with an electron gun that generates an electron beam, a tube body, a multi-staged depressed collector for collecting the electron beam, and a magnetic solenoid. The electron beam travels through the tube body. The magnetic solenoid produces a magnetic flux that focuses the electron beam as it travels through the tube body. The magnetic flux includes a portion that threads through the electron gun. The IOT is adapted to reduce this portion of the magnetic flux in order to provide improvements in the efficiency of the IOT.
