    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.
