The VERT-X project, financed by ESA and started in January 2019 by a Consortium led by INAF and which includes EIE, Media Lario Technologies, GPAP, and BCV Progetti, aims to design an innovative calibration facility. In the VERT-X design the parallel beam, needed for calibration, is produced placing a source in the focus of an X-ray collimator. This system is mounted on a raster-scan mechanism which covers the entire ATHENA optics. The compactness of the VERT-X design allows a vertical geometry for the ATHENA calibration facility, with several potential benefits with respect to the long horizontal tube calibration facilities.ELETTRONICOenConference paper10.1117/12.25307132-s2.0-85076884150000535242800017https://www.spiedigitallibrary.org/conference-proceedings-of-spie/11119/2530713/VERT-X--VERTical-X-ray-raster-scan-facility-for/10.1117/12.2530713.short?SSO=12019SPIE11119E..0OMFIS/05 - ASTRONOMIA E ASTROFISICA
