TL;DR: In this paper, a series of carefully designed validation experiments has been performed on the DIII-D tokamak to obtain comprehensive multifield, multipoint, multiwavenumber fluctuation measurements and their scalings with key dimensionless parameters.

TL;DR: In this paper, it was shown that the relaxation oscillations are coupled core-edge modes amenable to wall-stabilization, and that fast ion losses which previously dictated a large plasma-wall separation to avoid wall over-heating, can be reduced to classical levels with sufficient plasma density.

TL;DR: The observation of stiff fast-ion transport suggests that reduced models can be used to effectively predict alpha profiles, beam ion profiles, and losses to aid in the design of optimized scenarios for future burning plasma devices.

TL;DR: In this article, the evolution of the q profile is measured using motional Stark effect polarimetry and the integer qmin crossings are further pinpointed in time by the observation of Alfven cascades.

TL;DR: Ono et al. as discussed by the authors used nonresonant magnetic fields for spinning the plasma and found that the torque from these fields can be enhanced at low rotation, which assists in spinning the plasmas from rest, and offers increased resistance against plasma slowing.
