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: In this paper, the authors describe a two-stage MHD instability, where the first stage is caused by a loss of energy from the central region and the second stage is due to an increase in impurity radiation.

TL;DR: Early operation of the Alcator C-MOD tokamak [I.H. Hutchinson et al., 1990] is surveyed and the edge plasma shows a wealth of marfe-like phenomena, including a transition to detachment from the divertor plates with accompanying radiative divertor regions.

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.

TL;DR: A series of pellet-fueling experiments has been carried out on the Alcator $C$ tokamak as mentioned in this paper, where high-speed hydrogen pellets penetrate to within a few centimeters of the magnetic axis, raise the plasma density, and produce peaked density profiles.
