Abstract

A fully relativistic theory of axial injection orbitron maser (AXIOM) oscillators has been completed. The theory models the interaction of axially injected electrons in helical trajectories with the fields of a coaxial cavity resonator. The theory treats TE or TM modes with sinusoidal axial field profiles. The power transferred from the electron beam to the cavity fields is calculated in terms of a general distribution function and the cavity parameters. A cold beam distribution function is used to evaluate the theory. The results of the theory are presented in terms of the threshold value of the cavity Q times the electron beam current IBeam required for self-oscillation.
