Paper Abstract

MPE will provide the X-ray Survey Telescope eROSITA for the Russian Spektrum-Roentgen-Gamma Mission to be launched in 2013. It consists of a compact bundle of 7 co-aligned mirror modules with a focal length of 1600 mm and 54 nested mirror shells each. Therefore, its sensitivity in terms of effective area, field-of-view (61'), and angular resolution (15" HEW on-axis) will yield a high grasp of about 1000 cm2 deg2 around 1 keV with an average angular resolution of ~26" HEW over the field-of-view (30" including optical and spacecraft error contributions). After an extended test program on single mirror shells, assembled test modules (6 shells) and a qualification model we have now started integration of flight mirror modules. We give a résumé on the development and test program including key improvements to the shell integration method. Moreover, we report on the integration progress and present first results on the X-ray performance of partially integrated mirror modules.
