Paper Abstract

The Advanced X-ray Astrophysics Facility--Imaging is one of two complementary space-based x-ray observatories being developed by NASA. Utilizing grazing incidence mirror elements in a Wolter Type I configuration, it will image x-ray sources over an energy range of 0.1 to 10 KeV. This paper describes the deposition of iridium/chromium coatings on Zerodur substrates using DC magnetron sputtering for use in grazing incidence configuration. Included are a description of the configuration and parameters of the deposition process, the results of x-ray performance measurements, and the implications of the results for scaling the deposition process to the full scale AXAF-I mirror elements.
