Heavy particle processes in high power plasmas

Based on the models developed for the heavy particle transport in high power plasmas in the second funding period, this subproject is now dedicated to a consistent and continuous description of heavy particle processes taking into account the inherent surface interactions and their feedback (i.e., from the target via the transport toward the substrate). Two complementary approaches are pursued: i) The present model of the gas phase is extended in terms of reactive processes; ii) The plasma – surface interaction (up to Ti-Al-O-N) is self-consistently investigated using classical molecular dynamics and coupled back to the model of the gas phase. Together with experimental results this allows for a unified, synergetic process investigation.
