The mm-wave cold cathode peniomagnetron

The distinctive features of the peniotron device-a millimeter wave source with a peniotron mechanism of the electron-wave interaction on the high harmonics of the cyclotron frequency are considered. This device uses an adiabatic electronic-optical system (EOS) with a cold cathode. The EOS generates a large-orbit helical electron beam which releases the energy to the high frequency (HF) field in the space interaction of the source electrodynamic system (EDS). The EDS represents a coaxial cavity based on the round-shaped waveguide with an azimuthal periodic vane structure and slot-type resonators (magnetron waveguide). The scheme of the source makes it possible to operate in the modes of through gyroresonance or autoresonance. The first results of the investigation into the cold-cathode electron gun holds a greater promise for the devices based on such a system
