Use of Silicon Pore Optics for a SF Class Deployed Telescope

摘要

X-ray optics based on pore geometries have opened applications for X-ray telescopes in the planetary and astrophysics areas where very restricted resources are allowed. In this paper the mission design for a limited size X-ray telescope is presented, which is based on a stowed structure to be deployed in a L2 orbit. With the application of silicon based pore optics in the conical approximation of the Wolter geometry an appreciable effective area can be achieved at 1keV. The energy response function can be extended and optimised towards higher energies by the application of more complex reflective coatings including multiplayer designs. The angular resolution is kept compatible with this collecting area, avoiding source confusion. One of the workhorse launchers for the ESA science missions, the Soyuz Fregat, is assumed as vehicle. The main trade-offs of the mission design will be addressed and the performance of such a telescope is discussed.
