Issue Date: | 2016 | Volume: | Advances in X-Ray/EUV Optics and Components XI | Editors: | Khounsary, Ali M.; Goto, Shunji; Morawe, Christian | Series: | PROCEEDINGS OF SPIE | Number: | 9963 | First Page: | 996304 | Abstract: | The BEaTriX (Beam Expander Testing X-ray facility) project is an X-ray apparatus under construction at INAF/OAB to generate a broad (200́60 mm2), uniform and low-divergent X-ray beam within a small lab (6́15 m<SUP>2</SUP>). BEaTriX will consist of an X-ray source in the focus a grazing incidence paraboloidal mirror to obtain a parallel beam, followed by a crystal monochromation system and by an asymmetrically-cut diffracting crystal to perform the beam expansion to the desired size. Once completed, BEaTriX will be used to directly perform the quality control of focusing modules of large X-ray optics such as those for the ATHENA X-ray observatory, based on either Silicon Pore Optics (baseline) or Slumped Glass Optics (alternative), and will thereby enable a direct quality control of angular resolution and effective area on a number of mirror modules in a short time, in full X-ray illumination and without being affected by the finite distance of the X-ray source. However, since the individual mirror modules for ATHENA will have an optical quality of 3-4 arcsec HEW or better, BEaTriX is required to produce a broad beam with divergence below 1-2 arcsec, and sufficient flux to quickly characterize the PSF of the module without being significantly affected by statistical uncertainties. Therefore, the optical components of BEaTriX have to be selected and/or manufactured with excellent optical properties in order to guarantee the final performance of the system. In this paper we report the final design of the facility and a detailed performance simulation. | Conference Name: | Advances in X-Ray/EUV Optics and Components XI | Conference Place: | San Diego, CA, USA | Conference Date: | 31 August-1 September 2016 | URI: | http://hdl.handle.net/20.500.12386/24421 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9963/1/Design-and-advancement-status-of-the-Beam-Expander-Testing-X/10.1117/12.2238952.short | ISSN: | 0277-786X | ISBN: | 9781510603172 | DOI: | 10.1117/12.2238952 | Bibcode ADS: | 2016SPIE.9963E..04S | Fulltext: | open |
