Abstract

Terahertz gyrotrons in harmonic operation offer the magnetic-field reduction, but they also easily generate various competing modes that operate at low harmonics. In this paper, we used a nonlinear multi-mode code to comparatively analyze the second-harmonic TE8,9-mode backward-wave-driven gyrotron, forward-wave-driven gyrotron, and gyrotron traveling-wave amplifier (gyro-TWA).
