Controlling the boundary layer in fusion-grade, high-performance, plasma discharges is
essential for the successful development of toroidal magnetic confinement power generating …

Progress 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. Recent theoretical …

The DIII-D tokamak evolved from the earlier Doublet III device in 1986. Since then, the facility
has undergone a number of changes including the installation of divertor baffles and …

The physics of non-axisymmetry is a far more important topic in the theory of toroidal fusion
plasmas than might be expected.(1) Even a small toroidal asymmetry in the magnetic field …

A small relaxation of the axisymmetric magnetic field of a tokamak into a non-axisymmetric
three-dimensional (3D) configuration can be effective to control magnetohydrodynamic …

The development of techniques for neoclassical tearing mode (NTM) suppression or
avoidance is crucial for successful high beta/high confinement tokamaks. Neoclassical …

In the last two years, three major technical improvements have been made on J-TEXT in
supporting of the expanded operation regions and diagnostic capabilities.(1) The successful …

A tokamak relies on the axisymmetric magnetic fields to confine fusion plasmas and aims to
deliver sustainable and clean energy. However, misalignments arise inevitably in the …

SPARC is being designed to operate with a normalized beta of that rises linearly with a
change in the plasma current. Massive material injection is planned to reduce the disruption …

Values of the normalized plasma pressure up to twice the free-boundary stability limit
predicted by ideal magnetohydrodynamic (MHD) theory have been sustained in the DIII-D …
