X-RAY OPTICS

BRIEF DESCRIPTION

We propose the development of new advanced technologies for future X-ray astrophysics missions of ESA with focus on for large, precise and light-weight mirror shells. Technologies considered for detailed study and development include glass technologies, glossy (amorphous) metals, glossy carbon, and light ceramics replication. Results from the proposed project will match general needs of ESA for innovative technologies as well as they will be linked directly to the XEUS ESA mission under study.

The XEUS telescope design requires numerous thin mirror shells. Nearly 7 000 such shells will create the telescope mirror assembly.  Due to the use in space, the shells must not be only of very high accuracy, and surface quality, but also must be very light-weight. These requirements make the application of old technologies such as nickel electroforming replication less advantageous, since the classical nickel shells are relatively heavy. The mirror shells for the XEUS mirror assembly must be light-weight while keeping all other desired features.

The light weight but precise X-ray optics will be required for all major X-ray telescopes in the 21. century (requirements analogous to XEUS has also the US Constellation X project). Relevant various innovative technologies will be carefully exploited and tested.
