Gyrokinetic-neoclassical study of resonant magnetic perturbations in DIII-D

POSTER

Abstract

The gyrokinetic neoclassical, total-f, particle-in-cell code XGCa is utilized to study the kinetic effects of resonant magnetic perturbations (RMP) on a DIII-D H-mode plasma. Compared to the earlier efforts by G. Y. Park et al., [Phys. Plasmas 17, 102503 (2010), APS invited talk, Bull. Am. Phys. Soc. 56 (2011)] using the guiding center code XGC0, the gyrokinetic code XGCa adds important new capabilities to the study, such as a 2D Poisson solver and a fully nonlinear collision operator, which enhances the fidelity of the simulation in the H-mode pedestal and the scrape-off layer.
