Paper Abstract

Recently NASA Marshall Space Flight Center has made good progress in employing computer numerical control (CNC) polishing techniques on electroless nickel mandrels, as part of our replicated grazing incidence optics program. CNC polishing has afforded the ability to deterministically refine mandrel figure, therefore improving mirror performance. The Marshall Grazing Incidence X-ray Spectrometer (MaGIXS) is a MSFC-led sounding rocket instrument that comprises some of the first mirrors produced at MSFC using this polishing technique. Here we present the predicted mirror performance obtained from metrology, after completion of CNC polishing, as well as the results of X-ray tests performed on the MaGIXS telescope mirror before, and after mounting.
