The physics of magnetically confined plasmas has had much of its development as part of
the program to develop fusion energy and is an important element in the study of space and …

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 …

A basic theoretical framework is developed for the investigation of tearing mode interactions
in cylindrical geometry. A set of equations describing the coupled evolution of the amplitude …

An investigation is made into the electron temperature perturbations associated with tearing
modes in tokamak plasmas. It is found that there is a critical magnetic island width below …

Experimental results from the COMPASS-C tokamak reveal a sharp threshold in amplitude
above which externally applied static resonant magnetic perturbations (RMPs) induce …

Disruptions and related vertical displacement events pose a major problem to the design
and operation of future tokamak reactors. The cause and dynamics of disruptions will be …

We apply “rotating wall” electric fields to spin up a non-neutral plasma in a Penning-
Malmberg trap, resulting in steady-state confinement (weeks) of up to 10 9 Mg+ ions. The …

Theoretical guidance is needed on two disruption questions:(1) When is a tokamak
operating in a metastable state in which loss of control is credible (avoidance question)?(2) …

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 …
