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.

TL;DR: It is shown in the Joint European Torus that NTMs can be readily destabilized by long-period sawteeth, such as obtained by sawtooth stabilization from ion-cyclotron heating or current drive, which has important implications for burning plasma scenarios, as alpha particles strongly stabilize the saweeth.
Journal ArticleDOI
Cross–machine benchmarking for ITER of neoclassical tearing mode stabilization by electron cyclotron current drive

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
Error field mode studies on JET, COMPASS-D and DIII-D, and implications for ITER

TL;DR: In this article, the critical scalings of error field sensitivity and harmonic content effects were identified, enabling predictions to be made of the requirements for larger devices such as ITER Thresholds are lowest at low density, a regime proposed for H mode access on ITER.
Journal ArticleDOI
Dimensionless scaling of the critical beta for onset of a neoclassical tearing mode
TL;DR: In this paper, a database from high-constraint H-mode with ELMs and periodic central sawteeth was compiled from the tokamaks ASDEX Upgrade (AUG) [Plasma Phys. Controlled Fusion 41, 767 (1999)], DIII-D [Nucl. Fusion 38, 987 (1998)], and JET (Joint European Torus) [PLasma Phys., B1 (1999)] and a comparison was made of the measured critical beta for onset of the m/n=3/2 mode (m and
