Deuterium inventories have been measured in plasma facing components of ASDEX Upgrade. Nearly 60% of the total D-inventory was observed in the lower inner divertor target plate in redeposited layers of low-Z material. The outer divertor, however, was found to be dominated by erosion processes and correspondingly retained a much lower amount of deuterium. The D-inventory at the main chamber plasma facing components can be explained by a model employing implantation of charge-exchange neutrals, which yields very good agreement with the experimental findings for all surfaces not exposed to direct ion fluxes.
