Abstract

Abstract In this study, 3D orbit-following simulations with the ASCOT code of a tracer injection experiment on ASDEX Upgrade (AUG) are carried out to investigate the influence of toroidal field (TF) ripple and resonant magnetic perturbations (RMPs) on global ¹³C transport in the scrape-off layer (SOL). The conducted ASCOT simulations predict ripple to induce toroidal periodicity into the ¹³C deposition pattern. For resonant magnetic perturbations, the deposition pattern was observed to be locally influenced in the vicinity of the in-vessel coils creating the perturbations. In both cases, however, the global large-scale deposition of ¹³C remained unchanged compared to the case of an axisymmetric magnetic field.
