  • Patent number: 6486604
    Abstract: For a traveling-wave valve arrangement with a traveling-wave valve and a linearizing circuit arrangement, it is proposed to design the linearizing circuit arrangement and the traveling-wave valve as one constructional unit and, for the thermal protection of the linearizing circuit arrangement in the simultaneous presence of a high permissible temperature of the valve housing, to maintain the circuit arrangement by means of an active cooling element at a nondamaging temperature lower than the one of the wall of the valve or of a common wall. The cooling element is preferably a Peltier element.

  • Patent number: 5260623
    Abstract: An electron-beam tube with an electron collector for an electron-beam entering the electron collector in an electron-beam direction. A plurality of large-area projections are provided for heat radiation including a funnel-shaped projection expanding in the electron-beam direction. The funnel-shaped projection includes a smaller opening which is one of directly and indirectly fastened to the collector and including an upstream projection including a surface which is first with respect to the electron-beam direction, the surface facing the arriving electron-beam and the surface being provided with low heat radiation properties. All other surfaces of the plurality of projections having high heat radiation properties higher than the low heat radiation properties. The collector and the plurality of projections being supported by a satellite as a travelling-wave tube with the electron collector radiating into space.
