abstract = {ITER as the next-level fusion device is intended to
reliably produce more fusion power than required for
sustainably heating its plasma. Modeling has been an
essential part of the ITER design and for planning of future
experimental campaigns. In a tokamak or stellarator plasma
discharge, impurities play a significant role, especially in
the edge region. Residual gases, eroded wall material, or
even intentionally seeded gases all heavily influence the
confinement and, thus, the overall fusion performance.
Nitrogen is such a gas envisaged to be seeded into a
discharge plasma. By modeling the impurities kinetically
using the full three-dimensional Monte-Carlo code package
EMC3-EIRENE, we analyze the distribution of nitrogen
charge-state resolved in a seeded ITER baseline scenario and
draw conclusions for the hydrogen background plasma density.
Lastly, we compare the influence of a more refined kinetic
ion transport in EIRENE including additional physical
effects on the impurity density.},
