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 …

Tokamaks have demonstrated excellent plasma confinement capability because of their
symmetry but has an intrinsic drawback because of their pulsed inductive operation. Efforts …

For stable and efficient fusion energy production using a tokamak reactor, it is essential to
maintain a high-pressure hydrogenic plasma without plasma disruption. Therefore, it is …

A principal pressure limit in tokamaks is set by the onset of neoclassical tearing modes
(NTMs), which are destabilized and maintained by helical perturbations to the pressure …

A new paradigm is presented to reconstruct the plasma current density profile in a tokamak
in real-time. The traditional method of basing the reconstruction on real-time diagnostics …

Neoclassical tearing modes (NTMs) will be the principal limit on performance in ITER in the
standard scenario, which has beta well below the ideal kink limit. Measurements of island …

Strongly-shaped diverted negative triangularity (NT) plasmas in the DIII-D tokamak
demonstrate simultaneous access to high normalized density, current, pressure, and …

Neoclassical tearing modes (NTMs) are magnetic islands which increase locally the radial
transport and therefore degrade the plasma performance. They are self-sustained by the …

Magnetic islands are a ubiquitous feature of magnetically confined plasmas. They arise as
the result of plasma instabilities as well as externally imposed symmetry-breaking …

A selection of achievements and first physics results are presented of the European
Integrated Tokamak Modelling Task Force (EFDA ITM-TF) simulation framework, which aims …
