Steven Sabbagh,Stanley Kaye,Jonathan Menard,F. Paoletti,M.G. Bell,R. E. Bell,J.M. Bialek,Manfred Bitter,E.D. Fredrickson,D.A. Gates,Alan H. Glasser,H.W. Kugel,L. L. Lao,B.P. LeBlanc,R. Maingi,Ricardo Maqueda,E. Mazzucato,D. Mueller,Masayuki Ono,S.F. Paul,M. Peng,C.H. Skinner,Dan Stutman,G. A. Wurden,W. Zhu +24 more
TL;DR: In this paper, the evolution of the plasma equilibrium between discharges is analyzed with an automated version of the EFIT code and reconstructed magnetic signals are fitted to the corresponding measured values with low errors.
Journal ArticleDOI

Wampler,Leonid E. Zakharov +29 more
TL;DR: Ono et al. as discussed by the authors applied lithium coatings to plasma facing components found previously in limited plasmas can occur also in high-power diverted configurations, and the results showed that benefits from the coatings were sometimes, but not always, seen.
Journal ArticleDOI
Plasma response to lithium-coated plasma-facing components in the National Spherical Torus Experiment
M.G. Bell,H.W. Kugel,Robert Kaita,Leonid E. Zakharov,H. Schneider,B.P. LeBlanc,D.K. Mansfield,R. E. Bell,R. Maingi,S Ding,Stanley Kaye,S.F. Paul,S.P. Gerhardt,John Canik,J. C. Hosea,G. Taylor +15 more
TL;DR: Experiments in the National Spherical Torus Experiment (NSTX) have shown beneficial effects on the performance of divertor plasmas as a result of applying lithium coatings on the graphite and carbon-fiber-composite plasma-facing components as mentioned in this paper.

TL;DR: In this article, the stability limits in the National Spherical Torus Experiment (NSTX) have increased significantly recently due to a combination of device and operational improvements, reaching (not simultaneously) βT = 35%, βN = 6.4, βN/li = 10, and βP = 1.4.
