Impact of screening of resonant magnetic perturbations in three dimensional edge plasma transport simulations for DIII-D
Original language description
The impact of resonant magnetic perturbations (RMPs) on the plasma edge can be analyzed in detail by three dimensional computer simulations, which take the underlying magnetic field structure as input. Previously, the "vacuum approximation" has been usedto calculate the magnetic field structure although plasma response effects may result in a screening (or even an amplification) of the external perturbations. Simulation results for an ITER similar shape plasma at the DIII-D tokamak are presented for the full vacuum perturbation field and an ad hoc screening case in comparison to the unperturbed configuration. It is shown that the RMP induced helical patterns in the plasma edge and on the divertor target shrink once screening is taken into account. However, a flat temperature profile is still found in the "open field line domain" inside the separatrix, while the "density pump out effect" found in the vacuum RMP case is considerably weakened.
