Divertor stray light analysis in JET-ILW and implications for the H- diagnostic in ITER

We report on the first results for the spectrum of divertor stray light (DSL) and the signal-to-background ratio for D-alpha light emitted from the far SOL and divertor in JET in the recent ITER-like wall (ILW) campaign. The results support the expectation of a strong impact of DSL upon the H alpha (and Visible Light) Spectroscopy Diagnostic in ITER.
