Neoclassical transport processes are important to the understanding of plasma confinement
physics in doubly periodic magnetized toroidal plasmas, especially, after the impact of the …

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

The objectives of NSTX-U research are to reinforce the advantages of STs while addressing
the challenges. To extend confinement physics of low-A, high beta plasmas to lower …

Key plasma physics and real-time control elements needed for robustly stable operation of
high fusion power discharges in ITER have been demonstrated in recent research …

The snowflake magnetic configuration is characterized by the presence of two closely
spaced poloidal field nulls that create a characteristic hexagonal (reminiscent of a …

A quantitative interpretation of the experimentally measured high-pressure plasma response
to externally applied three-dimensional (3D) magnetic field perturbations, across the no-wall …

In this paper, we review the thermal plasma confinement and transport properties observed
and predicted in low aspect ratio tokamaks, or spherical tokamaks (STs), which can depart …

This paper describes the range of variations in edge and SOL turbulence observed using a
gas puff imaging (GPI) diagnostic in NSTX discharges. The database consists of 140 shots …

We review progress made on the advanced tokamak path to fusion energy by the DIII-D
National Fusion Facility (Luxon et al. in Nucl Fusion 42: 614, 2002). The advanced tokamak …

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