Abstract

The invention describes a vacuum electronic device comprising an electron source having at least one cathode for emitting of electrons, at least one electron beam guidance cavity for concentrating electrons emitted from the cathode, said cavity having an entrance aperture and an exit aperture, a portion of an inner side of said cavity around the exit aperture being provided with an insulating material, and a first electrode being connectable to a first power supply means for applying, in operation, an electric field with a first field strength E1 between the cathode and the exit aperture to allow electron transport throught he electron beam guidance cavity, wherein the cathode comprises a carbon-based cold emitter.
