X-ray tests of the MMs are currently performed at the PTB laboratory of the BESSY synchrotron facility in pencil beam configuration, but they require a PSF reconstruction. Full illumination X-ray tests could be performed using a broad, low-divergent X-ray beam like the one in use at PANTER (MPE, Neuried, Germany), but the large volume to be evacuated makes it impossible to perform the functional tests at the MMs production rate (3 MM/day). <BR /> To overcome these limitations, we started in 2012 to design a facility aimed at generating a broad (170 x 60 mm<SUP>2</SUP>), uniform and low-divergent (1.5 arcsec HEW) X-ray beam within a small lab (∼ 9 x 18 m<SUP>2</SUP>), to characterize the ATHENA MM. BEaTriX (the Beam Expander Testing X-ray facility) makes use of an X-ray microfocus source, a paraboloidal mirror, a crystal monochromation system, and an asymmetrically-cut diffracting crystal for the beam expansion. These optical components, in addition to a modular low-vacuum level (10<SUP>-3</SUP> mbar), enable to match the ATHENA SPO acceptance requirements. <BR /> The realization of this facility at INAF-OAB in Merate (Italy) is now on going. Once completed, BEaTriX can be used to test the Silicon Pore Optics modules of the ATHENA X-ray observatory, as well as other optics, like the ones of the Arcus mission. In this paper we report the advancement status of the facility. | Acknowledgments: | The development of the BEaTriX facility is funded by the ESA contract No. 4000123152/18/NL/BW, “Advanced and Compact X-ray Test facility for the ATHENA SPO module”, the AHEAD consortium activities financed by the EU Horizon 2020 grant No. 654215, and INAF internal funds. | Titolo del convegno: | International Conference on Space Optics — ICSO 2018 | Luogo del convegno: | Chania ,Greece | Periodo del convegno: | 9-12 October, 2018 | URI: | http://hdl.handle.net/20.500.12386/28806 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/11180/2535997/BEaTriX-Beam-Expander-Testing-X-ray-facility-for-testing-ATHENAs/10.1117/12.2535997.full?SSO=1 | ISSN: | 0277-786X | ISBN: | 9781510630772 | DOI: | 10.1117/12.2535997 | Bibcode ADS: | 2019SPIE11180E..26S | Fulltext: | open |
