Issue Date: | 2015 | Volume: | Optics for EUV, X-Ray, and Gamma-Ray Astronomy VII | Editors: | O'Dell, Stephen L.; Pareschi, Giovanni | Series: | PROCEEDINGS OF SPIE | Number: | 9603 | First Page: | 96030L | Abstract: | Athena (Advanced Telescope for High Energy Astrophysics) is an x-ray observatory using a Silicon Pore Optics telescope and was selected as ESA's second L-class science mission for a launch in 2028. The x-ray telescope consists of several hundreds of mirror modules distributed over about 15-20 radial rings. The radius of curvature and the module sizes vary among the different radial positions of the rings resulting in different technical challenges for mirror modules for inner and outer radii. We present first results of demonstrating Silicon Pore Optics for the extreme radial positions of the Athena telescope. For the inner most radii (0.25 m) a new mirror plate design is shown which overcomes the challenges of larger curvatures, higher stress values and bigger plates. Preliminary designs for the mounting system and its mechanical properties are discussed for mirror modules covering all other radial positions up to the most outer radius of the Athena telescope. | Conference Name: | SPIE Optical Engineering + Applications, 2015 | Conference Place: | San Diego, CA, USA | Conference Date: | 9-13 August, 2015 | URI: | http://hdl.handle.net/20.500.12386/23545 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9603/1/Silicon-pore-optics-mirror-modules-for-inner-and-outer-radii/10.1117/12.2187486.short | ISSN: | 0277-786X | ISBN: | 9781628417692 | DOI: | 10.1117/12.2187486 | Bibcode ADS: | 2015SPIE.9603E..0LW | Fulltext: | open |
