A larger-diameter boss 61a in the end hat 61 extends to the interior of an interaction space, a smaller-diameter boss 61b and one end 3a of the filament 3 are secured to each other, and the other end 3b is secured to a boss 7a of the end hat 7. Here, the dimension of an axial free length part F which forms an electron emission part which is not secured to the end hats 61 and 7 of the filament 3 is set to 50% or more and 80% or less of the axial dimension H of plate-like vanes 2, and the electron emission part is arranged so as to be displaced to the output side.

Abstract: The present invention relates to electronics and particularly to field emitters used in M-type microwave devices. The design of a multi-layer field emitter is proposed which has at least one operating film and supporting films, providing mechanical strength and preventing penetration of corrosion materials into the operating film at high operating temperatures. The supporting films could be produced from the same material or material with linear expansion coefficients equal or close to that of the operating film material. Built-in mechanical stress can cause not only deformation but also a break of the film during its exploitation in a wide range of temperatures. In the inventive structure the thermal stresses in the operating film during an emission from its surface are lower due to good thermal contact with supporting films.

Abstract: A radio frequency magnetron device for generating radio frequency power includes a cathode at least partially formed from a diamond material. An anode is disposed concentrically around the cathode. An electron field is provided radially between the anode and the cathode. First and second oppositely charged pole pieces are operatively connected to the cathode for producing a magnetic field in a direction perpendicular to the electric field. A filament is provided within the electron tube which when heated produces primary electrons. Alternatively, a voltage is applied to the anode which causes primary electrons to emit from the diamond coated cathode. A portion of the primary electrons travel in a circular path and induce radio frequency power. Another portion of the primary electrons spiral back and collide with the cathode causing the emission of secondary electrons. The secondary electron emission sustains operation of the magnetron device once the device has been started.
