In many tokamak and stellarator experiments around the globe that are investigating energy
production via controlled thermonuclear fusion, electron cyclotron heating and current drive …

Long-term options for a steady-state DEMOnstration power plant may require the availability
of gyrotrons with an operating frequency significantly above 200 GHz together with an RF …

We propose a robust way of advancement of the gyrotrons into the region of terahertz
frequencies and MW-level power of radiation while retaining high efficiency and high …

High frequency (> 230 GHz) megawatt-class gyrotrons are planned as RF sources for
electron cyclotron resonance heating and current drive in DEMOnstration fusion power …

We present the results of the development of a highly stable gyrotron (with long‐term
stability of an operating frequency of 170 GHz being equal to 10− 9) for experiments on …

This article presents the realistic initial design studies of a 300-GHz, 1-MW, conventional-
cavity gyrotron for its probable application in the next-generation thermonuclear fusion …

High-power, high-frequency gyrotrons are the only promising sources for the electron
cyclotron resonance heating and current drive (ECRH&CD) in the present thermonuclear …

We show that during phase locking of the oscillations of a megawatt-level gyrotron by a
relatively weak external monochromatic signal, the phase and frequency modulation of the …

The primary problem that gyrotrons encounter is mode competition during their
development, especially multi-mode multi-frequency gyrotrons. In this paper, the influence of …

We analyze the effect of non-ideal characteristics of a tubular electron beam (spread of initial
transverse velocities, finite beam thickness, displacement, and misalignment of the electron …
