Nonlinear Analysis of a Magnicon Output Cavity

Abstract

A nonlinear analysis of the wave-particle interaction in the output cavity of a frequency-doubling magnicon amplifier is presented. The cavity is immersed in an axial magnetic field wherein electronics interact with a rotating TM210 mode via a gyro-resonant mechanism. The electron equations of motion and the wave equation for the radio-frequency field are derived and expressed in terms of scaled variables in order to study the general scaling of the output cavity. Single-electron, time-dependent simulation of the interaction in the cavity is performed to assess the accessibility and stability of high-efficiency states for an X-band magnicon. Results from multi-electron, steady-state simulation are presented to show the effect of spreads in electron beam radius, energy and transverse momentum on the efficiency.
