Year: 2023

Type: Doctoral dissertation

Plasma facing components (PFC) in fusion devices are exposed to plasma. Plasma-wall interaction processes are important as they impose a series of constraints on the components. The lifetime of the PFCs is dominantly determined by two processes: erosion and fuel retention. At the first wall the erosion is caused by …
