Abstract

The Imaging X-ray Polarimetry Explorer (IXPE) mission, done in collaboration between NASA and the Italian Space Agency (ASI), has been successfully detecting x-ray polarization from celestial sources for more than one year. This mission comprises three x-ray optics and three x-ray polarization sensitive detectors. Four calibration sources based on ⁵⁵Fe nuclides, one producing polarized radiation (at two energies) and three producing unpolarized radiation, are present on board with each detector. In this contribution we present the in-flight monitoring and calibration of IXPE using these sources, with particular regard to the calibrations of the spectral and polarization response. We also show the monitoring of the optics half-power diameter.
