Mirrors: X-Ray Telescopes
Scientific paper
A large number of mirror shells are required for ESA's XMM telescope three mirror modules, each of which consists of 58 thin walled highly nested Wolter I mirrors. The specified performance of the XMM mirror modules requires new design concepts and application of new technologies for the production of the lightweight mirror shells. The first full size XMM mirror shell was successfully replicated, having the following characteristics: total length 600 mm, maximum shell diameter 400 mm, carrier material/thickness graphite-epoxy/0.8 mm, replication layers gold/epoxy, and total replicated mirror surface 7500 cm2. The development, preparation, and mirror shell replication are described, and the first results of the performance of the mirror shell after measurements and X-ray testing are presented.
