Abstract

One of the challenges faced within the astronomical X-ray community is how to produce lightweight high angular resolution optics for a future X-ray mission capable of probing the early X-ray universe. To this end, the differential deposition project at NASA Marshall Space flight Center (MSFC) is looking to improve current X-ray optic technology by applying a corrective coating with a goal of achieving arc-second-level resolution. This paper will focus on the correction of segmented glass optics fabricated at NASA Goddard Space Flight Center (GSFC) and the paper will highlight: the design of the vacuum chamber and internal mechanics; the algorithm used to perform the correction; metrology of the glass segments; and the improvement post correction that has been achieved to date.
