CF-LIBS quantification and depth profile analysis of Be coating mixed layers

• LIBS & SIMS depth profiles analysis of Be-based layers containing C, O, H, D-fuel. Deconvolution D α and H lines by Lorentz fitting for the quantification H. MESB plot Stark broadening line evaluation T e n , resp. Determination fuel content CF-LIBS comparison with TOF-ERDA IBA. Study variation elemental composition when changing . A remote system is being considered as an tool in ITER monitoring erosion retention first wall. This necessitates further investigation performance thick co-deposited consisting ITER-relevant materials. The main goal this work determining samples profile to compare results those obtained other methods. studied were mixed coatings on W substrates, some cases or both. These impurities are relevant not only ITER, but also fusion devices, such JET-ILW. laser ablation was performed at 10 mbar Ar pressure using a 5 ns pulse Nd:YAG 1064 nm. Suitable Be spectral employed electron temperature plasma multi-elemental Saha-Boltzmann (MESB) plots. density from following deconvolution. average each coating then calibration-free (CF-LIBS) agreement techniques (TOF–ERDA, IBA).
