Analysis and Efficiency Optimization of Gyroresonance Devices with Traveling-T-Wave Cavities

摘要

Four types of two-beam gyroresonance devices with traveling-T-wave cavities and an accelerating electrode (gyromonotrons with vertically and horizontally polarized T waves and with the wave propagating at an angle to the beam and cascaded systems) are studied. The efficiency at the first (second) harmonic of the cyclotron frequency in one- and two-stage devices reaches 30 (20) and 60 (50)%, respectively. High-powered wide electron beams can be used in the devices under study owing to the absence of the effect of dynamic beam stratification.
