Journal ArticleDOI
Blob birth and transport in the tokamak edge plasma: analysis of imaging data
James Myra,D.A. D'Ippolito,D.P. Stotler,Stewart Zweben,B.P. LeBlanc,Jonathan Menard,R.J. Maqueda,Jose Boedo +7 more
TL;DR: In this article, high-speed high-spatial-resolution data obtained by the gas puff imaging (GPI) diagnostic on the National Spherical Torus Experiment (NSTE) is analyzed and interpreted in light of recent theoretical models for electrostatic edge turbulence and blob propagation.
Journal ArticleDOI
Blob structure and motion in the edge and SOL of NSTX
Stewart Zweben,J.R. Myra,W. Davis,D.A. D'Ippolito,T.K. Gray,S.M. Kaye,B.P. LeBlanc,R.J. Maqueda,D. A. Russell,D.P. Stotler +9 more
TL;DR: In this paper, the structure and motion of discrete plasma blobs (a.k.a. filaments) in the edge and scrape-off layer of NSTX was studied for representative Ohmic and H-mode discharges.
Beta-limiting MHD Instabilities in Improved-performance NSTX Spherical Torus Plasmas
J. E. Menard,M. G. Bell,R. E. Bell,E.D. Fredrickson D.A. Gates: S.M. Kaye,B. Leblanc,R. Maingi,D. Mueller,S. A. Sabbagh,D. Stutman,C.E. Bush,D.W. Johnson,R. Kaita,H.W. Kugel,R.J. Maqueda,F. Paoletti,S. F. Paul,M. Ono,Yueng Kay Martin Peng,C. H. Skinner,E. J. Synakowski +19 more
TL;DR: The NSTX global magnetohydrodynamic stability limits in the National Spherical Torus Experiment (NSTX) have increased significantly recently due to a combination of device and operational improvements as mentioned in this paper.
Journal ArticleDOI
Edge and SOL turbulence and blob variations over a large database in NSTX
Stewart Zweben,W. Davis,S.M. Kaye,J.R. Myra,R.E. Bell,B.P. LeBlanc,R.J. Maqueda,Tobin Munsat,S.A. Sabbagh,Y. Sechrest,D.P. Stotler +10 more
TL;DR: In this paper, the authors describe the range of variations in edge and SOL turbulence observed using a gas puff imaging (GPI) diagnostic in NSTX discharges, and evaluate these variations with respect to both the global and local edge plasma parameters, and compared with simplified theoretical models.
Journal ArticleDOI

Stewart Zweben,R.J. Maqueda,J.L. Terry,Tobin Munsat,J.R. Myra,D.A. D'Ippolito,D. A. Russell,John A. Krommes,B.P. LeBlanc,T. Stoltzfus-Dueck,D.P. Stotler,Kyron Williams,C.E. Bush,R. Maingi,Olaf Grulke,S.A. Sabbagh,Anne White +16 more
TL;DR: Ono et al. as discussed by the authors compared the structure and motion of edge turbulence observed in L-mode vs H-mode plasmas in the National Spherical Torus Experiment (NSTX).
