Terahertz Gyrotrons at High Cyclotron Harmonics with Irregular Electrodynamic Systems
Two experimental gyrotron test benches in the terahertz frequency range with large-orbit electron beams operating at high harmonics of the cyclotron frequency are created at the Russian Academy of Sciences’ Institute of Applied Physics. An overview is presented of work aimed at developing advanced irregular microwave systems for these gyrotrons. The aim of this work is to reduce ohmic losses and improve the selectivity of operating wave excitation at high harmonics.
