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: The first six months of MAST operations have been remarkably successful as discussed by the authors, with a plasma current of over 1 MA with central plasma temperatures (ohmic) of order 1 keV.

TL;DR: In this paper, the resonant magnetic perturbation (RMP) fields, including the plasma response, are computed within a linear, full toroidal, single-fluid resistive magnetohydrodynamic (MHD) model, and under realistic plasma conditions for MAST and ITER.

Abstract: Values of ${\ensuremath{\beta}}_{T}\ensuremath{\ge}30%$ have been achieved and sustained for several confinement times on the START spherical tokamak using additional heating provided by neutral beam injection. These values are more than twice the highest value previously obtained in a tokamak, and correspond to normalized $\ensuremath{\beta}$ values of ${\ensuremath{\beta}}_{N}\ensuremath{\ge}4$. In these shots values of ${I}_{p}g{I}_{\mathrm{rod}}$ (where ${I}_{\mathrm{rod}}$ is the current flowing in the central toroidal field rod) have been obtained, which are considered to be necessary for spherical tokamak power plant. The results are compared with ideal-MHD stability theory.

TL;DR: In this paper, the authors showed that the growth of the n = 1 resistive wall mode (RWM) can be influenced by an external magnetic field applied in closed loop feedback using a six element error field correction coil (C coil).
