ABRIXAS (A BRoad-band Imaging X-ray All-sky Survey) was a German astronomy spacecraft intended to monitor X-ray emissions in the universe. The imaging telescope, operating in the 0.5-10 keV X-ray range, was to map an estimated 10,000 new sources. The instrument was actually seven Wolter-1 telescopes of focal length 160 cm each with 27 nested mirrors of length 30 cm and diameters shrinking from 16.3 cm to 7.6 cm. The seven fields of view, each of 40 arc-minutes diameter, were separated by 7 degrees from each other. Additional details may be seen at:
