The calibration of flight mirror modules for the ART-XC instrument on board the SRG mission

MSFC is fabricating x-ray optics for the Astronomical Roentgen Telescope - X-Ray Concentrator (ART-XC or ART for short) instrument under agreements with the Russian Space Research Institute (IKI). ART-XC is one of two instruments that will be launched on the Russian-German Spectrum-Roentgen-Gamma (SRG) Mission to be launched in 2016(1). Delivery of the flight optics for ART-XC (7 mirror modules) is currently scheduled for summer/fall of 2014(2). MSFC has to date completed assembly of four modules and has performed extensive calibration on two of these. These calibrations show that the modules meet effective area requirements and greatly exceed the angular resolution requirements. Details of the calibration procedure and an overview of the results obtained to date are presented here.
