Direct fabrication of full-shell x-ray optics

Abstract

The next generation of astrophysical missions will require fabrication technology capable of producing high angular resolution x-ray mirrors. A full-shell direct fabrication approach using modern robotic polishing machines has the potential for producing stiff and light-weight shells that can be heavily nested, to produce large collecting areas, and are easier to mount, align and assemble, giving improved angular resolution. This approach to mirror fabrication, is being pursued at MSFC. The current status of this direct fabrication technology is presented.
