Issue Date: | 2021 | Volume: | Optics for EUV, X-Ray, and Gamma-Ray Astronomy X | Editors: | O'Dell, Stephen L.; Gaskin, Jessica A.; Pareschi, Giovanni | Series: | PROCEEDINGS OF SPIE | Number: | 11822 | First Page: | 118220K | Abstract: | The ATHENA X-ray telescope will be the largest X-ray optics ever built. The ground calibration of this mirror assembly raises significant difficulties due to its unprecedented size, mass and focal length. The VERT-X project aims at developing an innovative calibration system which will be able to accomplish to this extremely challenging task.The design is based on an X-ray parallel beam produced by an X-ray source positioned in the focus of a highly performing X-ray collimator; the beam will be accurately moved by a raster-scan mechanism covering all the ATHENA optics at different off-axis angles. The main driving factor in the VERT-X design is the ATHENA calibration requirement on the accuracy in the HEW measure which is 0.1", all over the field of view. The VERT-X project, started in January 2019, is financed by ESA and conducted by a consortium that includes INAF together with EIE, Media Lario, BCV Progetti and GPAP. | Conference Name: | Optics for EUV, X-Ray, and Gamma-Ray Astronomy X | Conference Place: | San Diego, California, United States | Conference Date: | 1-5 August, 2021 | URI: | http://hdl.handle.net/20.500.12386/36664 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/11822/2593670/The-VERT-X-calibration-facility--development-of-the-most/10.1117/12.2593670.short https://api.elsevier.com/content/abstract/scopus_id/85117766401 |
