Complicated Electrodynamic Systems for Sub-THz High-Harmonic Gyrotrons

Abstract

We describe a series of works aimed at creating high-harmonic gyrotrons with cavities of complicated shapes as a way to increase efficiencies of their operation and to improve their selective properties. These works are mainly aimed at the implementation of the large-orbit gyrotrons developed at our Institute on the basis of two experimental installations. At the same time, some approaches have proved attractive also for traditional gyrotron configurations.
