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 manipulation of power deposition on divertor targets at DIII-D by the application of resonant magnetic perturbations (RMPs) for suppression of large type-I edge localized modes (ELMs) is analyzed.
Journal ArticleDOI

TL;DR: In this paper, a study of three-dimensional (3D) perturbed magnetic field structures and transport for edge localized mode control experiments with resonant magnetic perturbations at DIII-D is presented.
Journal ArticleDOI
Particle, heat, and sheath power transmission factor profiles during ELM suppression experiments on DIII-D
J. G. Watkins,Todd Evans,M. W. Jakubowski,R.A. Moyer,Oliver Schmitz,Andreas Wingen,M. E. Fenstermacher,Ilon Joseph,C. J. Lasnier,D.L. Rudakov +9 more
TL;DR: In this paper, a three-peak structure of a toroidal pattern predicted by the TRIP3D code was observed to get ∼2× larger during ELM suppression than between ELMs before the RMP is turned on.
Journal ArticleDOI

Brooks,M. E. Fenstermacher,Ch. Fuchs,A. Huber,A. Kallenbach,Anthony Leonard,A. Meigs,D.L. Rudakov,Diii-D Team,Jet-Efda Contributors +24 more
TL;DR: In this article, the UEDGE code of radiated power, and ion saturation currents and power loads to the target plates have been compared for density scans in ohmic and low confinement mode plasmas in DIII-D, ASDEX Upgrade, and JET simulations including cross-field drifts and assuming elevated chemical sputtering yields of 3%−4% move the numerical solutions closer to many of the measurements compared to omitting the drifts.
