Large-orbit M-type oscillator with the adiabatic electron-optical system

The large-orbit M-type oscillator with the adiabatic electron-optical system in the specific drift-orbital resonance mode is considered. A theoretical analysis of electron trajectories is made. According to early estimates, this system is free from shortcomings typical for a gyrotron and a peniotron when an operating wavelength becomes shortened to a millimeter and submillimeter band.
