Juergen Rapp,P. Monier-Garbet,G. F. Matthews,R. Sartori,P. Andrew,Pierre Dumortier,T. Eich,Wojciech Fundamenski,M. von Hellermann,J.T. Hogan,L. C. Ingesson,S. Jachmich,H. R. Koslowski,A. Loarte,G. Maddison,D. C. McDonald,A. Messiaen,J. Ongena,V.V. Parail,V. Philipps,G. Saibene,B. Unterberg,Jet Contributors +22 more
TL;DR: In this article, the authors investigated methods for reducing divertor heat loads in order to increase the lifetime of divertor tiles in future fusion reactors and compared argon and nitrogen seeded type-III ELMy H-modes.
Journal ArticleDOI
Helium transport and exhaust studies in enhanced confinement regimes in DIII-D
M. R. Wade,D. L. Hillis,J.T. Hogan,R. Maingi,M. M. Menon,M.A. Mahdavi,W.P. West,K. H. Burrell,P. Gohil,R. J. Groebner,R.M. Hong,D. H. Kellman,J. C. Phillips,R. Seraydarian,D.F. Finkenthal +14 more
TL;DR: In this article, a detailed analysis of the helium profile evolution indicates that the exhaust rate is limited by the exhaust efficiency of the pump and not by the intrinsic helium transport properties of the plasma.
