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

TL;DR: Control of the toroidal plasma rotation with external momentum input by injection of tangential neutral beams indicates that for large plasmas such as in future fusion reactors with low rotation, the requirement of the additional feedback control system for stabilizing RWM is much reduced.
Journal ArticleDOI

TL;DR: In this paper, the authors used a simple neutral gas shielding (NGS) model with inclusion of the effect of fast ions on the ablation and the subsequent behavior of the plasma have been investigated.
Journal ArticleDOI

TL;DR: In this article, a burst period increases as the drop ratio of the neutron emission increases, and the mode amplitude increases with the observed growth rate for fast frequency sweeping (fast FS) modes.
Journal ArticleDOI
Nonlocal energetic particle mode in a JT-60U plasma
TL;DR: Ishida et al. as mentioned in this paper used a simulation code for magnetohydrodynamics and energetic particles to investigate the instability in a Japan Atomic Energy Research Institute Tokamak-60 Upgrade (JT-60U).
