LASER-INDUCED PLASMA SPECTROSCOPY OF PLASMA FACING MATERIALS

Abstract

Abstract Qualitative elemental analysis of ASDEX divertor plates' material was performed by laser-induced plasma spectroscopy. The spectra show a decrease in impurity signals and an increase in substrate signal during the layer-by-layer ablation. The selective detection of the plasma light is reasonable for obtaining emission spectra resembling those attained using time-gated detectors
