چکیده
The Imaging X-ray Polarimetry Explorer is a mission dedicated to the measurement of polarization from tens astrophysical sources belonging different classes. Expected be launched at end 2021, payload comprises three mirrors and focal plane imaging polarimeters, latter being designed built in Italy. While calibration always an essential phase development high-energy space missions, for IXPE it has been particularly extensive both calibrate response polarization, which peculiar IXPE, achieve statistical uncertainty below expected sensitivity. In this paper we present equipment that was INAF-IAPS Rome, Italy, polarization-sensitive detectors on-board IXPE. Equipment includes sources, polarized unpolarized, stages align move beam, test their mechanical assembly. all these equipments were fit specific needs Instrument calibration, versatility could also used future other projects.
