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.
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
Structure and motion of edge turbulence in the National Spherical Torus Experiment and Alcator C-Moda)
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).
Journal ArticleDOI
Saturation mechanisms for edge turbulence
TL;DR: In this paper, a Braginskii-type fluid model using the scrape-off-layer turbulence code is used to study the interaction of edge and scrape-offslayer turbulence, blob generation, momentum transport, and shear flow generation in 2D turbulence.

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.
