Journal ArticleDOI
Observation of plasma toroidal-momentum dissipation by neoclassical toroidal viscosity.
W. Zhu,Steven Sabbagh,R. E. Bell,J.M. Bialek,M.G. Bell,B.P. LeBlanc,Stanley Kaye,Fred Levinton,Jonathan Menard,Ker-Chung Shaing,Aaron Sontag,Howard Yuh +11 more
TL;DR: Quantitative agreement between experiment and theory is found when the effect of toroidally trapped particles is included and the measured decrease of the plasma toroidal angular momentum profile is compared to calculations of nonresonant drag torque based on the theory of neoclassical toroidal viscosity.
Journal ArticleDOI

Jonathan Menard,S.P. Gerhardt,M.G. Bell,J.M. Bialek,A. Brooks,John Canik,J. Chrzanowski,M. Denault,L. Dudek,D.A. Gates,Nikolai Gorelenkov,W. Guttenfelder,R. Hatcher,J. Hosea,Robert Kaita,Stanley Kaye,C.E. Kessel,Egemen Kolemen,H.W. Kugel,R. Maingi,M. Mardenfeld,D. Mueller,B. A. Nelson,C. Neumeyer,M. Ono,E. Perry,R. Ramakrishnan,R. Raman,Yang Ren,S. Sabbagh,M.

TL;DR: The National Spherical Torus eXperiment (NSTX) is a MA-class spherical tokamak (ST) facility in the US actively developing the physics basis for an ST-based FNSF as discussed by the authors.
Journal ArticleDOI
Electromagnetic transport from microtearing mode turbulence.
W. Guttenfelder,Jeff Candy,S.M. Kaye,W. M. Nevins,E. Wang,R.E. Bell,Gregory W. Hammett,B.P. LeBlanc,D. R. Mikkelsen,Howard Yuh +9 more
TL;DR: This Letter presents nonlinear gyrokinetic simulations of microtearing mode turbulence, which include collisional and electromagnetic effects and use experimental parameters from a high-β discharge in the National Spherical Torus Experiment to predict the predicted electron thermal transport.
Journal ArticleDOI
Active stabilization of the resistive-wall mode in high-beta, low-rotation plasmas.
Steven Sabbagh,R. E. Bell,Jonathan Menard,D.A. Gates,Aaron Sontag,J.M. Bialek,B.P. LeBlanc,Fred Levinton,Kevin Tritz,Howard Yuh +9 more
TL;DR: The resistive-wall mode is actively stabilized in the National Spherical Torus Experiment in high-beta plasmas rotating significantly below the critical rotation speed for passive stability and in the range predicted for the International Thermonuclear Experimental Reactor.
Journal ArticleDOI
Advances in global MHD mode stabilization research on NSTX
Steven Sabbagh,John Berkery,R.E. Bell,J.M. Bialek,S.P. Gerhardt,Jonathan Menard,Riccardo Betti,D.A. Gates,B. Hu,O. Katsuro-Hopkins,B.P. LeBlanc,Fred Levinton,J. Manickam,Kevin Tritz,Howard Yuh +14 more
TL;DR: In this article, the stability of resistive wall modes and global kink/ballooning modes was investigated under active control. But the authors focused on the non-resonant n = 1 mode, and not on the n = 3 mode.
