Myasnikov,E. A. Soluyanova,V. I. Malygin +30 more
TL;DR: In this paper, the authors show that an increasing fraction of electron heating increases the transport in the ion channel mainly due to the dependence of the ITG dominated ion transport on the ratio Te/Ti in agreement with modeling.
Journal ArticleDOI
Comparison of Different Methods for Calculating Gyrotron Quasi-Optical Mode Converters
TL;DR: In this article, the authors present the use of combination of three methods for calculation and synthesis of high-efficiency microwave mode converters, such as radiators of gyrotrons.
Journal ArticleDOI
Microwave source of multigigawatt peak power based on a relativistic backward-wave oscillator and a compressor
V. L. Bratman,G. G. Denisov,N. G. Kolganov,Sergey V. Mishakin,Sergey V. Samsonov,Dmitry I. Sobolev +5 more
TL;DR: In this article, the effect of passive compression of frequency-modulated pulses in dispersive media is used to raise the microwave radiation peak power to a multigigawatt level.
Journal ArticleDOI
Multifrequency gyrotron with high-efficiency synthesized waveguide converter
A. V. Chirkov,G. G. Denisov,A. N. Kuftin,V. E. Zapevalov,V. I. Malygin,Mikhail A. Moiseev,S. Yu. Kornishin +6 more
TL;DR: The results of numerical simulation and experimental investigation of a prototype of a megawatt multifrequency gyrotron for controlled thermonuclear fusion facilities are presented in this article, which operates at six frequencies in the range 105-152 GHz with small diffraction losses in the internal quasi-optical system and a high Gaussian mode content in the output beam.
Journal ArticleDOI
Experimental observation of high-Q modes at the center of a resonance band of two-dimensional Bragg structures
N. Yu. Peskov,Naum S. Ginzburg,G. G. Denisov,V. Yu. Zaslavskiĭ,S. V. Kuzikov,A. S. Sergeev,Andrey V. Arzhannikov,Petr V. Kalinin,S. L. Sinitskiĭ,Manfred Thumm +9 more
TL;DR: In this article, the electrodynamic characteristics of two-dimensional Bragg resonance structures of planar geometry have been studied and the measured frequency dependences of the coefficients of transmission and transverse scattering agree well with theoretical analysis within the framework of the geometric optics approximation.
