TL;DR: The National Compact Stellarator Experiment (NCSX) as discussed by the authors was designed to enhance the magnetohydrodynamic (MHD) stability without feedback or nearby conducting structures and provide drift-orbit confinement similar to tokamaks.

TL;DR: In this paper, the authors describe the construction of stepped-pressure equilibria as extrema of a multi-region, relaxed magnetohydrodynamic (MHD) energy functional that combines elements of ideal MHD and Taylor relaxation, and which they call MRXMHD.

TL;DR: Steady state solutions for anisotropic heat transport in a chaotic magnetic field are determined numerically and compared to a set of "ghost surfaces"-surfaces constructed via an action-gradient flow between the minimax and minimizing periodic orbits in remarkable agreement with the temperature contours.

TL;DR: In this paper, the authors consider the linear and nonlinear ideal plasma response to a boundary perturbation in a screw pinch and demonstrate that three-dimensional, ideal-MHD equilibria with continuously nested flux-surfaces and with discontinuous rotational transform across the resonant rational surfaces are well defined and can be computed both perturbatively and using fully nonlinear equilibrium calculations.

TL;DR: In this paper, a method to design coils for stellarators is presented, where each discrete coil is represented as an arbitrary, closed, one-dimensional curve embedded in three-dimensional space.
