TL;DR: The framework made possible the design and automation of a workflow that enables self-consistent predictions of kinetic profiles and the plasma equilibrium, and it was found that the feedback between the transport fluxes and plasma equilibrium can significantly affect the kinetic profiles predictions.

TL;DR: In this article, a new sustained high performance regime, combining discrete edge and core transport barriers, has been discovered in the DIII-D tokamak, where edge localized modes are replaced by a steady oscillation that increases edge particle transport, thereby allowing particle control with no ELM-induced pulsed divertor heat load.

TL;DR: Fusion power has been increased by a factor of 3 in DIII-D by tailoring the pressure profile to avoid the kink instability in H-mode plasmas by controlling the plasma pressure profile width.
The role of zonal flows in the saturation of multi-scale gyrokinetic turbulence
TL;DR: In this paper, the 2D spectrum of the saturated electric potential from gyrokinetic turbulence simulations that include both ion and electron scales (multi-scale) in axisymmetric tokamak geometry is analyzed.

TL;DR: In this article, the radial profiles of two fluctuation fields were measured and compared to nonlinear gyrokinetic simulations in neutral beam-heated, sawtooth-free low confinement mode (L-mode) plasmas in DIII-D [J. L. Luxon, Nucl. Fusion 42, 614].
