    Abstract: 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.

    Abstract: An object of the present invention is to provide a vacuum tube with a structure close to that of an inexpensive and easily available vacuum fluorescent display which easily operates as an analog amplifier. A vacuum tube subject to the present invention comprises: a filament which is tensioned linearly and emits thermoelectrons, an anode arranged parallel to the filament, and a grid arranged between the filament and the anode such that the grid faces the anode. The present invention is characterized in that a distance between the filament and the grid is between 0.2 mm and 0.6 mm, including 0.2 mm and 0.6 mm.
