Abstract

The paper describes both simulated and experimental results observed in high cyclotron harmonic peniotron oscillators with magnetron waveguide resonators and discusses the operation modes of the oscillation. We made the modes clear by considering interactions between an axis encircling electron beam and the space harmonic components of the respective modes generated in the magnetron waveguides. To make it possible to operated at higher frequencies, we introduced a new concept for designing high cyclotron harmonic tubes based on a space harmonic of the 2 π mode interaction. We then presented design parameters for a number of peniotron tubes operable up to 300 GHz with relatively low magnetic field
