A progress report on grazing incidence optics fabrication and evaluation
The progress being made on a mirror array telescope for high energies (MARTHE) project is reported. As a first step, small mirror flats and full-size Wolter I mirrors are produced that are lacquer coated (mandrels) and then coated with gold or palladium. The up-to-date results of fabricating and testing these mirrors are presented. Currently, results can be provided on the micro-roughness, marco-figure, X-ray scattering, and reflectivity up to 8 keV from flats and Wolter I mirrors as well as optical measurements of the flats.
