Abstract

We report measurements of the extreme ultraviolet reflectivity of gold from 44 to 920Å at grazing incidence. Gold was deposited using vacuum evaporation and electroplating on substrates of glass and polished nickel respectively. We also present measurements of the extreme ultraviolet reflectivity of electroless nickel in the same wavelength region, where one of the polished nickel substrates was used as a sample. Derived optical constants for evaporated and electroplated gold and electroless nickel are presented. Additional studies of the effects of various contaminants on the EUV reflectivity are also reported. The variations of the optical constants are discussed in terms of density variations, surface roughness and contamination effects. These results are reported as part of studies for the Extreme Ultraviolet Explorer satellite program to determine acceptance criteria for the EUV optics, contamination budgets and calibration plans.
