The peniomagnetron with barrel-shaped resonator

A source of millimeter (mm) waves with a peniotron mechanism of electron-wave interaction on high harmonics of cyclotron frequency for generation of high stability coherent radiation is suggested. An adiabatic electronic-optical system (EOS) is applied in the generator design. The EOS produces a large helical-orbit axis-encircling electron beam (EB), which gives up power to a high-frequency field in the interaction space of a generator electrodynamic system (GES). GES is constituted of the field-coupled resonator systems based on the gridwork cylinder waveguide with an azimuthally periodic structure of cutting slots and coaxially arranged barrel-shaped open resonator. The generated power is extracted from the barrel-shape cavity by a standard waveguide
