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.
Journal ArticleDOI
The role of kinetic effects, including plasma rotation and energetic particles, in resistive wall mode stabilitya)
John Berkery,S.A. Sabbagh,H. Reimerdes,Riccardo Betti,Bo Hu,R.E. Bell,Stefan Gerhardt,J. Manickam,Mario Podesta +8 more
TL;DR: Hu et al. as discussed by the authors found that alpha particles are required for resistive wall mode stability at presently expected levels of plasma rotation, and tested this theory in an experiment in the National Spherical Torus Experiment (NSTX) with various energetic particle contents.
Journal ArticleDOI
Resistive wall mode instability at intermediate plasma rotation.
John Berkery,Steven Sabbagh,Riccardo Betti,B. Hu,R.E. Bell,S.P. Gerhardt,J. Manickam,Kevin Tritz +7 more
TL;DR: Good agreement is found between an experimental RWM instability at intermediate plasma rotation and the RWM marginal point calculated with kinetic effects included, by the MISK code.
Journal ArticleDOI
Progress in understanding error-field physics in NSTX spherical torus plasmas
Jonathan Menard,R.E. Bell,David Gates,S.P. Gerhardt,Jong-Kyu Park,S.A. Sabbagh,John Berkery,A Egan,J. Kallman,S.M. Kaye,B.P. LeBlanc,Yueqiang Liu,Aaron Sontag,D. Swanson,Howard Yuh,W. Zhu +15 more
TL;DR: In this paper, an extensive array of magnetic sensors has been used to analyse error fields, to measure error-field amplification and to detect resistive wall modes (RWMs) in real time.
Journal ArticleDOI

TL;DR: In this article, the influence of the q-profile and E x B flow shear on transport has been studied in MAST and equilibrium flow shears has been included in gyro-kinetic codes, improving comparisons with the experimental data.
