"Modelling of Impurity Transport and Plasma-Wall Interaction in Fusion Devices with the ERO Code: Basics of the Code and Examples of Application";
Contribution to Plasma Physics, 56 (2016), 6-8; 622 - 627.

The 3D ERO code, which simulates plasma-wall interaction and impurity transport in magnetically confined
fusion-relevant devices is described. As application, prompt deposition of eroded tungsten has been simulated
at surfaces with shallow magnetic field of 3 T. Dedicated PIC simulations have been performed to calculate
the characteristics of the sheath in front of plasma-exposed surfaces to use as input for these ERO simulations.
Prompt deposition of tungsten reaches 100% at the highest electron temperature and density. In comparison to
more simplified assumptions for the sheath the amount of prompt deposition is in general smaller if the PIC-
calculated sheath is used. Due to friction with the background plasma the impact energy of deposited tungsten
can be significantly larger than the energy gained in the sheath potential.
