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 …

Poloidal and toroidal rotation has been recognized to play an important role in heat transport
and magnetohydrodynamic (MHD) stability in tokamaks and helical systems. It is well known …

Parametric scalings of the intrinsic (spontaneous, with no external momentum input) toroidal
rotation observed on a large number of tokamaks have been combined with an eye towards …

Abstract The Fusion Nuclear Science Facility (FNSF) is examined here as part of a two step
program from ITER to commercial power plants. This first step is considered mandatory to …

We present the first evidence for the existence of a neoclassical toroidal rotation driven in a
direction counter to the plasma current by nonaxisymmetric, nonresonant magnetic fields. At …

Stabilizing modes that limit plasma beta and reduce their deleterious effect on plasma
rotation are key goals for the efficient operation of a fusion reactor. Passive stabilization and …

An extensive study of intrinsic and controlled non-axisymmetric field (δB) impacts in KSTAR
has enhanced the understanding about non-axisymmetric field physics and its implications …

The resistive wall mode (RWM) instability in high-beta tokamaks is stabilized by energy
dissipation mechanisms that depend on plasma rotation and kinetic effects. Kinetic …

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

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 …
