TL;DR: Menard et al. as mentioned in this paper presented the first run of NSTX-U, which achieved state-of-the-art performance in terms of the number of pulses and toroidal fields.
Journal ArticleDOI
Helicity-flux-driven α effect in laboratory and astrophysical plasmas.
TL;DR: Direct numerical simulations are presented for a dominant contribution to the α effect, which can be cast in the functional form of a total divergence of an averaged helicity flux, called the helicity-flux-driven α (Hα) effect.
Journal ArticleDOI
Absence of complete finite-Larmor-radius stabilization in extended MHD.
TL;DR: Simulation and theoretical calculations indicate that complete FLR stabilization of the interchange mode may not be attainable by ion gyroviscosity or the two-fluid effect alone in the framework of extended MHD.
