Abstract

This study reports development and testing of coatings on silicon pore optics (SPO) substrates including pre and post coating characterisation of the x-ray mirrors using Atomic Force Microscopy (AFM) and X-ray reflectometry (XRR) performed at the 8 keV X-ray facility at DTU Space and with synchrotron radiation in the laboratory of PTB at BESSY II. We report our findings on surface roughness and coating reflectivity of Ir/B₄C coatings considering the grazing incidence angles and energies of ATHENA and long term stability of Ir/B₄C, Pt/B₄C, W/Si and W/B₄C coatings.
