MPE/Garching and the Astrophysical Institute in Potsdam developed the scientific payload, a set of seven hard X-ray imaging telescopes with an X-ray CCD detector which will carry out an all-sky survey in the 1-10 keV band with 30 arcsecond resolution.

The imaging pn-CCD detector used for ABRIXAS including electronics is identical with the EPIC-Maxi detector developed by MPE/IAAT for XMM.
