Abstract

It has been known for quite some time that thin, low atomic number (Z) overcoats on x-ray mirrors with high-Z coatings, for example, carbon on iridium, can provides acceptable reflectivity response at high x-ray energies while boosting reflectivity in the low energy range. Recent published work has complemented this idea by adding an intermediate-Z coating interposed between the low and high Z coatings—a so-called graded-Z coating—which also offers improved reflectivity response at mid-range x-ray energies. In this paper I discuss a simple methodology for designing and optimizing graded-Z coatings in the 0.1-10 keV energy band.
