Issue Date: | 2020 | Journal: | PROCEEDINGS OF SPIE | Volume: | Space Telescopes and Instrumentation 2020: Ultraviolet to Gamma Ray | Editors: | den Herder, Jan-Willem A.; Nikzad, Shouleh; Nakazawa, Kazuhiro | First Page: | 246 | Abstract: | IXPE (Imaging X-ray Polarimetry Explorer) is a NASA SMEX in a partnership with ASI. The focal plane Detector Units (DUs) and the Detector Service Unit (DSU) were developed by the Italian research Institutes INAF-IAPS and INFN and were manufactured by OHB-I. IXPE will investigate X-ray polarimetry in the 2-8 keV energy band. The payload comprises three identical telescopes, each composed of a mirror and a detector unit with an X-ray polarimeter based on the Gas Pixel Detector (GPD). A stray-light collimator (SLC) is mounted on the top of the DU to shield the GPD from background X-rays not coming from the optics. At the bottom of the SLC, an ions-UV filter is mounted to reduce the thermal load and to prevent ions and UV from entering the DU. The ions-UV filters consist mainly of 1 um LUXFilm (based on polyimide). During on-ground calibration activities of the IXPE DUs, X-ray transparency of DU-FM ions-UV filters was measured with monochromatic X-ray at 2.7 keV and 6.4 keV at INAF-IAPS. | Conference Name: | Space Telescopes and Instrumentation 2020: Ultraviolet to Gamma Ray | Conference Place: | California, United States | Conference Date: | 14-18 December, 2020 | URI: | http://hdl.handle.net/20.500.12386/31029 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/11444/1144463/IXPE-DU-FM-ions-UV-filters-characterization/10.1117/12.2567000.full?SSO=1 | ISSN: | 0277-786X | ISBN: | 9781510636750 9781510636767 |
