Peter Friedrich,Heinrich Bräuninger,Bernd Budau,Wolfgang Burkert,Josef Eder,Michael Freyberg,Gisela Hartner,M. Mühlegger,Peter Predehl,Markus Erhard,S. Gutruf,D. Jugler,Dirk Kampf,G. Borghi,Oberto Citterio,Massimiliano Rossi,Giuseppe Valsecchi,Dervis Vernani,M. Zimmermann +18 more
TL;DR: In this article, the X-ray survey telescope eROSITA was designed for the Russian Spektrum-Roentgen-Gamma Mission (SPG) to be launched in 2011, and the angular resolution was targeted to be 15 arc seconds half-energy width (HEW) on-axis.
Proceedings ArticleDOI

Giovanni Pareschi,Vincenzo Cotroneo,Daniele Spiga,Dervis Vernani,Marco Barbera,Maria Antonella Artale,Alfonso Collura,Salvatore Varisco,Gabriele Grisoni,Giuseppe Valsecchi,Barbara Negri +10 more
TL;DR: In this paper, the impact of using soft X-ray multilayer mirrors in future Xray telescopes is discussed, and soft Xray reflectivity tests performed on prototype samples presented.
Proceedings ArticleDOI

TL;DR: In this paper, the authors present details of the work carried out to build silicon stacks for a 12 m optics and to integrate them into mirror modules, and also present results of x-ray tests taking place at PTB's XPBF with synchrotron-radiation and the PANTER test facility.

TL;DR: In this article, the first 12 m focal length mirror modules were produced and three different radii under study: mirror modules for the inner radii (Rmin = 250 mm), outer radii(Rmax = 1500 mm) and middle radii((Rmid = 737 mm) are being developed in parallel).
