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.
Proceedings ArticleDOI

TL;DR: In this article, the first results of the direct grinding and polishing of prototypes shells made by fused silica with low thickness, representative of the WFXT optical design, are presented.
Proceedings ArticleDOI
Fitting X-ray multilayer reflectivities by means of the PPM code
Daniele Spiga,Alessandro Mirone,Claudio Ferrero,V. Cotroneo,Giovanni Pareschi,Manuel Sanchez del Rio,Dervis Vernani +6 more
TL;DR: In this paper, the authors present the layer-by-layer modelization of the characteristics of multilayer stacks (Ni/C, Pt/C) by a multi-parametric "global" automatic optimization to reach the best fitting performances.
Proceedings ArticleDOI
Soft x-ray reflectivity-enhancement in astronomical telescopes via overcoatings: alternative materials and deposition methods
G. Pareschi,Marta Civitani,Giorgia Sironi,Yang Yang,V. Cotroneo,Giuseppe Valsecchi,Luca Magagnin,Thorsten Döhring,Miranda Bradshaw,Vadim Burwitz,Carlo Pelliciari +10 more
TL;DR: In this article, a novel approach based on the use of thin layer of a Carbon-like materials deposited using a dip coating method is discussed, which can further enhance the soft X-ray effective area of future Xray telescopes.
