TL;DR: A review of recent advances in the area of MHD stability and disruptions, since the publication of the 1999 ITER Physics Basis document (1999 Nucl. Fusion 39 2137-2664), is reviewed in this paper.
Journal ArticleDOI
Cross–machine benchmarking for ITER of neoclassical tearing mode stabilization by electron cyclotron current drive
R. J. La Haye,R. Prater,R.J. Buttery,Nobuhiko Hayashi,Akihiko Isayama,M. Maraschek,L. Urso,H. Zohm +7 more
TL;DR: In this article, a common methodology is developed for fitting the saturated m/n = 3/2 island before (or without) ECCD in all four experimental devices, ASDEX upgrade, DIII-D, JET and JT-60U.
Journal ArticleDOI

TL;DR: In this paper, integrated simulations are performed to establish a physics basis, in conjunction with present tokamak experiments, for the operating modes in the International Thermonuclear Experimental Reactor (ITER).
Journal ArticleDOI
Stabilization of neoclassical tearing modes by electron cyclotron current drive in JT-60U
Akihiko Isayama,Naoyuki Oyama,Hajime Urano,T. Suzuki,Manabu Takechi,Nobuhiko Hayashi,Kazunobu Nagasaki,Yutaka Kamada,Shunsuke Ide,Takahisa Ozeki +9 more
TL;DR: In this article, an active control of neoclassical tearing modes (NTMs) by electron cyclotron current drive (ECCD) in JT-60U is described, showing the possibility of the coexistence of sawtooth oscillations and a small-amplitude NTM without large confinement degradation.
Journal ArticleDOI
