| Popis: | Aluminium and polypropylene filters in series were used to eliminate scattered light below 10 nm from a grazing incidence monochrometer on the Doublet III tokamak. The 1s-2p O VII and O VIII resonance lines near 2 nm were observed with good signal-to-background. The background signal is caused by scattered light of longer wavelength of which metallic impurities is an important part. (AIP) |
