Michael Lehnen,K. Aleynikova,P. Aleynikov,David Campbell,P. Drewelow,N.W. Eidietis,Yu. Gasparyan,Robert Granetz,Y. Gribov,N. Hartmann,E. M. Hollmann,V.A. Izzo,S. Jachmich,S.H. Kim,M. Kocan,H. R. Koslowski,D. V. Kovalenko,U. Kruezi,A. Loarte,S. Maruyama,G. F. Matthews,P. B. Parks,G. Pautasso,R.A. Pitts,C. Reux,V. Riccardo,R. Roccella,J. A. Snipes,A.J. Thornton,P. de Vries,Efda Jet Contributors +30 more
TL;DR: In this paper, a brief overview on the disruption loads and mitigation strategies for ITER and the physics basis which is continuously refined through the current disruption R&D programs is discussed.
Journal ArticleDOI
Effect of transonic flow in the ablation cloud on the lifetime of a solid hydrogen pellet in a plasma
P. B. Parks,R. J. Turnbull +1 more
TL;DR: In this article, a scaling law for the ablation rate and lifetimes of a solid hydrogen pellet in a plasma is given, and the results of these calculations give good agreement when compared with experiments.
Journal ArticleDOI
Spatial Uniformity of Laser-Accelerated Ultrahigh-Current MeV Electron Propagation in Metals and Insulators
Julien Fuchs,Julien Fuchs,Julien Fuchs,Thomas E. Cowan,Thomas E. Cowan,Patrick Audebert,H. Ruhl,H. Ruhl,Laurent Gremillet,Andreas Kemp,Andreas Kemp,Matthew Allen,Abel Blazevic,J. C. Gauthier,M. Geissel,Manuel Hegelich,Stefan Karsch,P. B. Parks,Markus Roth,Yasuhiko Sentoku,Yasuhiko Sentoku,Richard B. Stephens,E. M. Campbell +22 more
TL;DR: It is found that electron flow through metals is uniform and can be laser imprinted, whereas propagation through insulators induces spatial disruption of the fast electrons.
Journal ArticleDOI
Improved core fueling with high field side pellet injection in the DIII-D tokamak
Larry R. Baylor,T.C. Jernigan,S.K. Combs,Wayne A Houlberg,Masakatsu Murakami,P. Gohil,K. H. Burrell,C. M. Greenfield,R. J. Groebner,C. L. Hsieh,R.J. La Haye,P. B. Parks,G. M. Staebler,Diii-D Team,G. L. Schmidt,D.R. Ernst,E. J. Synakowski,Miklos Porkolab +17 more
TL;DR: In this article, deuterium pellets from the magnetic high field side (HFS) have been used to generate peaked density profile plasmas [peaking factor (ne(0)/〈ne〉) in excess of 3] that develop internal transport barriers when centrally heated with neutral beam injection.
Journal ArticleDOI
Mitigation of tokamak disruptions using high-pressure gas injection.
Dennis Whyte,T.C. Jernigan,David Humphreys,A.W. Hyatt,C.J. Lasnier,P. B. Parks,Todd Evans,Marshall N. Rosenbluth,P. L. Taylor,A.G. Kellman,D. S. Gray,E. M. Hollmann,S.K. Combs +12 more
TL;DR: High-pressure gas-jet injection of neon and argon is shown to be a simple and robust method to mitigate the deleterious effects of disruptions on the DIII-D tokamak.
