SPECTRAL SLICING X-RAY TELESCOPE.

Academic Article

Abstract

  • Layered synthetic microstructure (LSM) x-ray optics may be used to couple a conventional glancing incidence x-ray mirror to a high sensitivity x-ray detector. The LSM mirror is a thin-film multilayer optic that effectively reflects only narrow spectral slices of the incident radiation by Bragg diffraction. By the use of figured LSM optics, it is possible to magnify the x-ray image produced by the primary mirrors so as to maintain their high inherent spatial resolution when used with currently available solid-state detectors. The results of theoretical design and analysis studies of several Spectral Slicing X-Ray Telescope (SSXRT) systems utilized LSM mirrors figured as hyperboloids, spheres, ellipsoids, and constant optical path aspheric elements are presented. The rms spot size and point response function calculations are given for telescopes in which the LSM optics are designed to yield magnifications of 2X , 6X , and 8X . The results of tilt and decentration studies are discussed.
