The pursuit of steady-state economic production of thermonuclear fusion energy has led to
research on the stabilization of the external kink and the resistive wall mode. Advances in …

Experimental observations of driven and intrinsic rotation in tokamak plasmas are reviewed.
For momentum sources, there is direct drive from neutral beam injection, lower hybrid and …

A self-consistent kinetic model is developed to study the stability of the resistive wall mode in
toroidal plasmas. This model is compared with other models based on perturbative …

MAST plasmas with a safety factor above unity and a profile with either weakly reversed
shear or broad low-shear regions, regularly exhibit long-lived saturated ideal …

Abstract Small three-dimensional (3D) magnetic field perturbations have many interesting
and possibly useful effects on tokamak and quasi-symmetric stellarator plasmas. Plasma …

In the absence of any auxiliary torque input, the DIII-D plasma consists of nonzero toroidal
angular momentum, in other words, it rotates. This effect is commonly observed in tokamaks …

The intrinsic toroidal velocity, V ϕ, in DIII-D (Luxon 2002 Nucl. Fusion 42 614) H-modes is
measured to be nonzero in the pedestal region, in the direction of the plasma current, co-I p …

The low-aspect ratio, low magnetic field and wide range of plasma beta of NSTX plasmas
provide new insight into the origins and effects of magnetic field errors. An extensive array of …

Externally applied, non-axisymmetric magnetic fields form the basis of several relatively
simple and direct methods to control magnetohydrodynamic (MHD) instabilities in a …

Recent high-β DIII-D (Luxon JL 2002 Nucl. Fusion 42 64) experiments with the new
capability of balanced neutral beam injection show that the resistive wall mode (RWM) …
