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.

TL;DR: In this article, the authors summarize recent experimental findings on properties of the stochastic boundary in DIII-D tokamak, showing that the interaction of the magnetic perturbation and the magnetic equilibrium is of a resonant nature.
