High-Harmonic Large-Orbit Terahertz Gyrotrons for Physical Applications

  • Published:
Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

An overview is presented of research performed at two experimental facilities with large-orbit gyrotrons (LOGs) operating in the subterahertz frequency range at the high harmonics of the frequency of electron cyclotrons. The pulsed LOG facility (80–100 keV/0.7–1.0 A) is developed as a source of radiation with a frequency of 1 THz with a kilowatt level of output power intended for use in plasma applications. A continuous subterahertz LOG (30 keV/0.7 A) is developed as a prototype of a universal multifrequency source for spectroscopic applications. Complicated electrodynamic systems intended to improve the selectivity and efficiency of high cyclotron harmonics excitation in these devices and allow tuning of the frequency of generation are described as well.
