Integrated modelling of impurity transport in ASDEX Upgrade — •Daniel Fajardo1, Clemente Angioni1, Giovanni Tardini1, Emiliano Fable1, Pierre Manas2, Rachael McDermott1, and the ASDEX Upgrade Team1 — 1Max-Planck-Institut für Plasmaphysik, Garching, Germany — 2CEA/IRFM, Saint-Paul-les-Durance, France
A database of experimentally measured boron (B) density profiles at ASDEX Upgrade (AUG) [R.M. McDermott et al 2022 Nucl. Fusion 62 026006] is studied via 1.5D integrated modelling with ASTRA. An additional tungsten (W) impurity is evolved and the profile predictions are compared to experiments, which feature variations of the NBI–ECRH heating power mixture. The turbulent transport is calculated with the quasilinear codes TGLF and QuaLiKiz, allowing us to validate the impurity transport predictions of these models. The neoclassical component of B is calculated with NCLASS, whereas the FACIT model is used for W due to the stronger effects of rotation-induced poloidal asymmetries on heavy impurities. The correlation between the predicted logarithmic impurity density gradients and the main plasma gradients is discussed, also in comparison with gyrokinetic results. Moreover, in an additional set of simulations STRAHL is used for the self-consistent calculation of radiated power profiles, which are compared to experimental bolometry estimations.
