TL;DR: In this paper, the suppression of turbulence by the E×B flow shear and parallel Flow Shear in an arbitrary shape finite aspect ratio tokamak plasma using the two point nonlinear analysis was investigated.

TL;DR: In this article, the authors show that the addition of small resonant magnetic field perturbations completely eliminates ELMs while maintaining a steady-state high-confinement (H-mode) plasma.

TL;DR: Values of normalized beta, up to 4 ({percent}-{ital m}-T/MA), energy confinement are a factor of 3 better than {ital L} mode, and at least 50% of the noninductive plasma current in this regime demonstrates compatibility with requirements for a steady-state high-beta tokamak power plant.

TL;DR: A comparison of experiment with theory shows that shear in {ital E}{sub {ital r}} and {ital v}{ Sub {theta}} is sufficient to suppress edge fluctuations, and that ion-orbit loss is large enough to be the source of {itals v}{sub{theta}}, and that ions- orbit loss may play a causal role in the {ital L}-{ital H} transition.

TL;DR: In this paper, the authors compared the effect of small n = 3 resonant magnetic perturbations (RMP) in low average triangularity plasmas and in ITER similar shaped (ISS) plaasmas, with ITER relevant collisionalities.
