ART-XC/SRG: joint calibration of mirror modules and x-ray detectors

The Astronomical RoentgenTelescope – X-ray Concentrator (ART-XC) is a hard x-rayinstrument with energy response 6–30 keV that will to be launched on board of the Spectrum RoentgenGamma (SRG) Mission. ART-XC consists of seven co-aligned mirror modules coupled with seven focal plane CdTe double-sided strip detectors. The mirror modules had been fabricated and calibrated at the NASA Marshall Space Flight Center (MSFC). The Russian Space ResearchInstitute (IKI) has developed and tested the X-ray detectors. The joint x-ray calibration of the mirror modules and focal plane detectors was carried out at the IKI test facility. Details of the calibration procedure and an overview of the results are presented here.
