ART-XC / SRG overview

ART-XC is an X-ray grazing incidence mirror telescopes array onboard the Spectrum-Roentgen-Gamma (SRG) mission, that is currently scheduled for launch in March 2019. This instrument was developed by the Space Research Institute (IKI) and the All-Russian Scientific Research Institute for Experimental Physics (VNIIEF). The NASA Marshall Space Flight Center (MSFC) has developed and fabricated flight X-ray mirror modules. Each mirror module is aligned with a focal plane CdTe double-sided strip detector which will operate over the energy range of 4−30 keV, with an angular resolution of <1′, a field of view of ~0.3 deg2 in double reflection and an expected energy resolution of about 9% at 14 keV. The ART-XC instrument will be used to perform an all-sky survey simultaneously with the other instrument of the SRG mission, eROSITA, operational in a softer energy range 0.3-10 keV. We present an overview of the ARTXC/SRG instrument and an update on the current status of the project.
