TL;DR: The National Spherical Torus Experiment (NSTX) is being built at the Princeton Plasma Physics Laboratory to test the fusion physics principles for the spherical torus (ST) concept at the MA level as discussed by the authors.

TL;DR: The two-dimensional radial vs poloidal structure and motion of edge turbulence in the National Spherical Torus Experiment (NSTX) were measured using high-speed imaging of the visible light emission from a localized neutral gas puff.

TL;DR: This Letter presents nonlinear gyrokinetic simulations of microtearing mode turbulence, which include collisional and electromagnetic effects and use experimental parameters from a high-β discharge in the National Spherical Torus Experiment to predict the predicted electron thermal transport.

TL;DR: Investigation of the combined database suggests that the threshold dependence Pthres approximately=0.3neBT2.5 shows reasonable agreement with the data, and therefore lower threshold power for ITER.

TL;DR: Menard et al. as mentioned in this paper developed a blanket system capable of tritium breeding ratio TBR ≈ 1, a poloidal field coil set supporting high elongation and triangularity for a range of internal inductance and normalized beta values consistent with NSTX/NSTX-U previous/planned operation, and a long-legged divertor analogous to the MAST-U divertor which substantially reduces projected peak divertor heat-flux and has all outboard field coils outside the vacuum chamber and superconducting to reduce power consumption.
