14 July 2008 Large effective area high angular resolution x-ray optics
Author Affiliations +
The future large X-ray astrophysics observatories after XMM and Chandra will require novel optics to be developed, in order to provide the combination of large effective area, low mass and adequate angular resolution. In particular the XEUS mission candidate [1,2], as selected in the first slice of the Cosmic Vision 1525 programme, has stringent and demanding requirements on the performance of the required X-ray optics forming the core of the mission concept. A summary of the specific requirements and boundary conditions for the XEUS X-ray optics is provided, followed by an outline and status of the options being considered in the XEUS studies and technology preparations. A discussion of the main design parameters is done, in particular of the impact of the focal length choice, and the application of coatings. The feasibility of the mechanical implementation of the considered telescope optical design in a flight model is not addressed in this study.
