摘要： A helix slow-wave circuit for use in a linear-beam microwave tube device, comprises a first helix formed by a first wire-like member wound in a first sense at a plurality of turns, and a second helix formed by a second wire-like member wound at a plurality of turns in a second sense opposite to the first sense so as to coaxially surround and superpose on the first helix so that the first and second helixes intersect each other at suitable intervals along an axial direction of the helixes. The first helix is fixed to the second helix in at least some of intersecting points between the first and second helixes.

摘要： A helix type traveling wave tube comprises an evacuated envelope containing an electron gun assembly at one end thereof for forming and projecting a beam of electrons over an elongated beam path to an electron collector electrode at the opposite end of the envelope. A helix slow-wave circuit is arranged along the beam path intermediate the electron gun and the beam collector for electromagnetic interaction with the beam. In order to extract an amplified signal from the downstream end of the slow wave circuit, there is provided an coaxial line including an outer conductor air-tightly fixed at one end thereof to the evacuated envelope and an inner conductor having one end connected to an output end of the slow wave circuit. An output waveguide is air-tightly fixed to the other end of the coaxial line outer conductor in such a manner the other end of the coaxial line inner conductor extending into the output waveguide. Further, a ceramic hollow cylindrical member is positioned in the output waveguide to surround the other end of the coaxial line inner conductor, and is air-tightly fixed at opposite ends thereof to an inner wall of the output waveguide.

摘要： A traveling-wave tube has a slow wave circuit consisting of a constant phase velocity section extending from the electron gun side of the tube, and a phase velocity tapering section extending from the collector side of the tube in which the phase velocity of the electromagnetic wave is lower than in the constant phase velocity section. An attenuator is located at about the center of the constant phase velocity section. The ratio of the length of the phase velocity tapering section to the distance between the end of the attenuator which faces the collector side of the tube and the electron gun side end of the phase velocity tapering section is equal to, or less than 0.4.BACKGROUND OF THE INVENTION

摘要： A solid heat-dissipating member having an axial aperture to slidably receive a collector of a traveling-wave tube, includes at least one radial hole opening to the axial aperture. A contacting element having a spherical surface is accommodated in the radial hole so as to be held in pressure contact with the collector under the action of a biasing spring arranged in the radial hole. The collector can be held in good thermal-conducting relation with the heat-dissipating member without the danger of seizing and can be smoothly withdrawn therefrom when required.
