    摘要： The vacuum tube subject to the present invention comprises a filament and two pairs of a grid and an anode. The filament is tensioned linearly and emitting thermoelectrons. Both of the anodes are formed on the same face on a planar substrate. The filament is arranged parallel to the planar substrate at a position facing both of the anodes. Each of the grids is arranged, such that the grid faces the anode in the same pair at a first predetermined distance from the anode and has a second predetermined distance from the filament, between the anode and the filament. The vacuum tube comprises an intermediate filament fixing part fixing the filament at a position corresponding to an intermediate point between the anodes of the two pairs.

    摘要： An electron beam device includes a diamond layer positioned downstream from and in the path of an electron beam. This diamond layer has a conductance that is responsive to the electron beam. Two electrical contacts on the diamond layer provide connections to a power source and a load. When the electron beam is on, the diamond layer becomes conductive allowing electrical power to flow from the power source through the diamond layer to the load. Accordingly, the electron beam device can act as a switch, or the electron beam can be modulated to provide an amplifier. The diamond layer is capable of high temperature operation, resists crystal damage, resists corrosion, and provides a high breakdown voltage. At least one of the electrical contacts on the diamond layer preferably comprises a degeneratively doped diamond surface portion. The degeneratively doped diamond surface portion is relatively transparent to the electron beam, has a coefficient of thermal expansion that is matched with the diamond layer, and resists damage caused by the electron beam.

    摘要： An electron emitter that consists of: a low work function material including Lanthanum hexaboride or Iridium Cerium that acts as an emitter, a cylinder base made of high work function material that has a cone shape where the low work function material is embedded in the high work function material but is exposed at end of the cone and the combined structure is heated and biased to a negative voltage relative to an anode, an anode electrode that has positive bias relative to the emitter, and a wehnelt electrode with an aperture where the cylindrical base protrudes through the wehnelt aperture so the end of the cone containing the emissive area is placed between the wehnelt and the anode.
