Vortrag: Seminar Institut für Allgemeine Physik (IAP), TU Wien; 05.11.2019.

Nuclear fusion could be a clean and climate protecting energy source of the future, but still a lot of physical
and technical issues need to be solved. In order to operate a future fusion power plant economically the first
wall in the reactor must withstand the tremendous heat load and the continuous particle bombardment long
enough. To investigate the erosion of such plasma facing materials (PFM) of a fusion device under welldefined
laboratory conditions, the TU Wien quartz crystal microbalance technique (QCM) is ideally suited. Insitu
studies with the QCM allow a unique insight into the dynamics of material mixing, erosion phenomena
and particle retention processes. In addition, experimental results can be used to benchmark new surface
morphology sensitive BCA (binary-collision-approximation) codes, like TRI3DYN and SDTrimSP-3D. We can
show that by taking surface morphology information into account, the agreement with the experimental
results is greatly improved.
