High-power gyrotrons for electron cyclotron heating and current drive
TL;DR: In many tokamak and stellarator experiments around the globe that are investigating energy production via controlled thermonuclear fusion, electron cyclotron heating and current drive (ECH&CD) are used for plasma start-up, heating, non-inductive current drive and MHD stability control.
Journal ArticleDOI
Method for synthesis of waveguide mode converters
TL;DR: In this paper, an iterative method for synthesis of waveguide mode converters is proposed, which offers fundamentally new solutions to the problems of mode converter development, and examples of synthesized converters calculated using this method are presented.
Journal ArticleDOI
Megawatt gyrotrons for ECR heating and current-drive systems in controlled-fusion facilities
TL;DR: In this paper, the results and main trends in developing megawatt gyrotrons used as microwave sources for electron-cyclotron wave systems in controlled-fusion facilities are discussed.
Journal ArticleDOI
High-efficiency wideband gyro-TWTs and gyro-BWOs with helically corrugated waveguides
TL;DR: In this article, the authors review the studies of gyrotron-type microwave devices whose electrodynamic system has the form of an oversized metal waveguide with a helically corrugated internal surface, such a corrugation changes radically the waveguide dispersion ensuring an almost constant group velocity of the eigenmode for a small (close to zero) longitudinal wave number in a wide frequency band.

TL;DR: In this paper, the first continuous wave gyrotron backward-wave oscillator with a helically rippled operating waveguide has been experimentally studied and a cyclotron harmonic with a maximum power of 7 kW and an efficiency of 15% at a frequency of 24.7 GHz was achieved.
