Evolution of Nonlinear Alfven Waves in Streaming Inhomogeneous Plasmas
B. Buti,V. L. Galinski,V. I. Shevchenko,Gurbax S. Lakhina,Bruce T. Tsurutani,Bruce E. Goldstein,Patrick Diamond,Mikhail V. Medvedev +7 more
TL;DR: In this article, a nonlinear evolution equation for Alfven waves propagating in streaming plasmas with nonuniform densities and inhomogeneous magnetic fields is obtained by using the reductive perturbation technique.

The negative triangularity tokamak: stability limits and prospects as a fusion energy system
S. Yu. Medvedev,S. Yu. Medvedev,Mitsuru Kikuchi,Laurent Villard,Tomonori Takizuka,Patrick Diamond,Hideki Zushi,Kazunobu Nagasaki,Xuru Duan,Y. Wu,A.A. Ivanov,A.A. Martynov,Yu.Yu. Poshekhonov,Ambrogio Fasoli,Olivier Sauter +14 more
TL;DR: In this paper, the edge stability, beta limits and power handling issues for negative triangularity tokamaks were discussed, and it was shown that plasmas with reactor-relevant values of normalized beta(N) > 3 can be stable to global kink modes without wall stabilization with appropriate core pressure profile optimization against localized mode stability.
Journal ArticleDOI
Theory of the Spatio-Temporal Dynamics of Transport Bifurcations
TL;DR: In this article, the development and time evolution of a transport barrier in a magnetically confined plasma with non-monotonic, nonlinear dependence of the anomalous flux on mean gradients is analyzed.
Journal ArticleDOI
Shear-induced Reynolds stress at the edge of L-mode tokamak plasmas
TL;DR: In this article, the structure of the flux-surface-averaged stress in the edge region of an L-mode tokamak plasma was investigated in the case of ballooning modes.
Journal ArticleDOI

TL;DR: In this article, the experimental fluctuation levels and turbulence characteristics can be reproduced by considering the nonlinear evolution of fluid-type equations, incorporating thermal and ionization drives, and the experimental results on the Texas Experimental Tokamak (TEXT) [Nucl. Technol/Fusion 1, 479 (1982)] and the Advanced Toroidal Facility (ATF) torsatron [Fusion Technol. 10, 179 (1986)].
