Nonlinear Theory of the Orbitron Maser in Three-Dimensions.
Abstract
The nonlinear analysis of the Orbitron Maser is studied numerically for an amplifier configuration in which an electron beam propagates through a coaxial waveguide with a voltage applied between the inner and out conductors. A set of coupled nonlinear differential equations is derived in three dimensions which governs the self consistent evolution of either the TE, TM, or TEM modes in a loss-free coaxial waveguide as well as the trajectories of an ensemble of electrons. The saturation efficiency as well as the linear growth rate are calculated and, although the linear growth rate for the orbitron amplifier is moderately high (about 1.0 dB/cm), the efficiency is low (somewhat < 6.1%). Severe limitations arise in the high frequency operation of the orbitron amplifier in the fundamental mode due to the break-down electric field and extremely small radius of the inner conductor.
