Abstract

For ESA's XMM Telescope three mirror modules, each consisting of 58 thin walled highly nested Wolter I mirrors, a large number of mirror shells are required. The specified performance of the XMM mirror modules require new design concepts and application of new technologies for the production of the lightweight mirror shells. Under ESA contract Zeiss leads an European industrial/scientific con-sortium to develop the technologies which allow production of real size XMM mirror shells by a dedicated metal/epoxy resin replication technique. In late 1988 the first full size XMM mirror shell was successfully replicated having the following characteristics: Total length: 600 mm Max. shell diameter: 400 mm Carrier material/thickness: CFRP/0.8 mm Replication layers: Gold/epoxy Total replicated mirror surface: 7500 cm2 Development, preparation and mirror shell replication are described. First results of the performance of the mirror shell after measurements and X-ray testing are presented.
