Abstract
This brief document reports the characterizations of X-ray reflectivity and scattering performed on platinum coating samples deposited at DTU on superpolished (rms < 2 Å) fused silica substrates. The samples represent preliminary tests for the deposition of the reflective coating on the parabolic mirror (in HOQ310 fused quartz) of the BEaTriX X-ray facility, in construction at INAF-OAB. The X-ray characterizations that have been performed at INAF-OAB encompass XRR tests at 8.045 keV, and low-res XRS measurements at the same energy. While the former returns a single roughness rms value within a non-precisely identified spatial frequency range, the latter return a reliable method for an independent measurement of the surface PSD.
