Fluctuations in the oscillations of a magnetron type backwardwave oscillator
Abstract
An attempt is made at developing a simple approximation procedure for calculating the spectral density of amplitude and phase fluctuations in the oscillations of a magnetron type backwardwave oscillator (MBWO) due to lowfrequency fluctuations in the electron beam current. The initial equations used are those expressing the equivalent line length, continuity, and motion. The amplitude and phase noise power, and rms fluctuations in frequency due to random variations in electron beam current, in particular shot effect, are determined. All calculations were carried out within the framework of the adiabatic approximation based on the thin beam model, for sake of simplification.
