| This research investigates LIBS for the analysis of contamination of plasma vessel walls (that are a mix of High and Low Z materials (W and Be)). Samples were 2um thick Be/W coatings on a Mo substrate, which contained D inclusions. Analysis was undertaken at high vacuum. Depth profiles were also recorded. Concentrations were estimated using CF-LIBS. The researchers were also able to resolved the D and H peaks in the spectrum | |||||
