Operation of the induced resonance electron cyclotron maser at higher harmonics
Abstract
The induced resonance electron cyclotron (IREC) maser operates at Doppler unshifted frequencies a = gammasq Omega sub 0/gamma, where gamma is the relativistic factor and Omega sub 0 is the cyclotron frequency. The frequency can be further increased by operation at higher cyclotron harmonics. A set of fasttime averaged nonlinear equations of motion is derived for the particle motion near an arbitrary harmonic. Startup currents are computed from the linear efficiency. The nonlinear efficiency is studied numerically for the first few harmonics. Minimization of the detrimental effects due to pitch angle and energy spread are investigated by selecting the optimum angle between the beam and the resonator.
