Abstract

The paper deals with the development of laser induced breakdown spectroscopy (LIBS) into an in situmethod for studying erosion/deposition processes at the first walls of fusion reactors. To this end, sam-ples extracted from the divertor tiles of ASDEX Upgrade after the 2009 plasma operations were analyzedusing LIBS for their composition and the results were compared with other post mortem deposition data.Quantitative depth profiles for the elemental concentrations were extracted from LIBS spectra by apply-ing a novel data processing method. In addition, both multiline and multispot averaging procedureswere applied to reduce fluctuations in the data. The LIBS concentration profiles matched qualitativelywith those given by secondary ion mass spectrometry and quantitatively with the ion-beam data. Thedeuterium content of the samples could be reliably determined if the surface densities were >1017at/cm2.
