Paper Abstract

ABRIXAS is a German satellite project - to be launched in spring 1999 - which will perform the first imaging x-ray all-sky survey in the 0.5-10 keV band thus being a complement to the ROSAT all-sky which covered the 0.1-2.4 keV range. The motivation of the project is a complete survey of sources that are missed by the ROSAT survey due to absorption. ABRIXAS will be also an ideal pathfinder for the forthcoming missions XMM and AXAF which will be launched in 1999, too. The ABRIXAS observatory will contain seven identical mirror modules, each consisting of 27 nested gold coated nickel shells of Wolter type I with a maximum diameter of 16 cm and a focal length of 160 cm. The optical systems are constructed by Carl Zeiss in replication technique and reach an on-axis resolution of better than 30 arcseconds. The focal planes of the seven telescopes share a 6 cm by 6 cm monolithic CCD detector of pn type developed by MPE and IAAT. It is nearly identical to that used for the XMM/EPIC camera and has the main advantages of high quantum efficiency and short readout cycles.
