Tungsten-rhenium alloy as a high-density absorber in ultra-short-period multilayer for hard X-ray mirrors

Ultra-short-period multilayer mirrors (period d below 5 nm) are key components for hard X-ray optics in the 20 keV–40 keV range, but their performance rapidly degrades when the period approaches a few nanometers due to density loss and/or interfacial defects (roughness or intermixing). In this work,...
