Paper Abstract

The European Space Agency's high throughput X-ray Telescope XMM (X-ray Multi Mirror Mission) has three modules each consisting of 58 highly nested monolithic Wolter I mirrors. The mirrors have diameters in the range between 300 and 700 mm, an axial length of 600 mm and a focal length of 7.5 m. Due to the high packing density within the mirror module the mirror shells have to be sufficiently thin, and due to the high number of mirrors the shells have to be as light as possible. In order to meet these requirements Carl Zeiss and Dornier have developed the CFRP/EPOXY mirror shell technology under ESA contract. In this paper the development and production of carriers of various sizes will be reported. It will be shown that the CFRP laminate with the lay-up chosen by Dornier is a good substrate for the replication of x-ray mirror shells.
