TL;DR: In this paper, a prototype Eletroformed-Nickel-Replicated (ENR) mirror module is presented for the Constellation-X mission, which consists of 5 shells of diameters from 150 mm to 280 mm and of 426 mm total length.

TL;DR: In this paper, a process to fabricate metal-ceramic replicated optics which will be lighter weight than current nickel replicated technology is presented. But this process is not suitable for X-ray astronomy missions, as it requires large diameter mirrors with thin cross sections allowing maximum nesting and increase in collecting area.

TL;DR: In this article, the first results concerning the effect of high-density materials on the reflectivity of X-ray observations were presented at the photon energies of 200 eV (i.e. below the carbon K absorption edge).

TL;DR: In this paper, a multilayer coating of integral cylindrical optics is developed to focus hard x-ray optics for future X-ray astronomy missions, and the results from both longitudinal and azimuthal uniformity coating tests are presented.

TL;DR: In this paper, the authors have shown how a thin layer of a light material, like carbon, on top of a traditional reflecting coating, can enhance the reflectivity in the soft x-ray spectral region (below 5 keV) without degrading the performances for higher energies.
