TL;DR: A review of recent advances in the area of MHD stability and disruptions, since the publication of the 1999 ITER Physics Basis document (1999 Nucl. Fusion 39 2137-2664), is reviewed in this paper.
Journal ArticleDOI

TL;DR: To calibrate diagnostics and benchmark dust dynamics modeling, precharacterized carbon dust has been injected into the lower divertor of DIII-D, and spectroscopic diagnostics observe an increase in carbon line (CI, CII, C(2) dimer) and thermal continuum emissions from the injected dust.
Journal ArticleDOI
Complete suppression of the m = 2/n = 1 neoclassical tearing mode using electron cyclotron current drive in DIII-D
Cc Petty,R.J. La Haye,T.C. Luce,David Humphreys,A.W. Hyatt,John Lohr,Ron Prater,E. J. Strait,M. R. Wade +8 more
TL;DR: The first suppression of the important and deleterious m = 2/n = 1 neoclassical tearing mode (NTM) was reported using electron cyclotron current drive (ECCD) to replace the missing bootstrap current in the island O-point as discussed by the authors.
Complete suppression of the m=2/n-1 neoclassical tearing mode using electron cyclotron current drive on diii-d
TL;DR: In this paper, the first suppression of the important and deleterious m=2/n=1 neoclassical tearing mode (NTM) was reported using electron cyclotron current drive (ECCD) to replace the ''missing'' bootstrap current in the island O-point.
Journal ArticleDOI

TL;DR: In this article, the authors used the peeling-ballooning modes model of edge magnetohydrodynamic stability as a working hypothesis to organize the data; several predictions of this theory are consistent with the experimental results.
