Mirror Systems for X-Ray Telescopes
As is known, studies of the soft x radiation of cosmic objects using proportional flow counters of large area are associated with considerable technical difficulties. At the same time, the use of reflecting x-ray optics is possible in this region of the spectrum (softer than l keV). It is advisable to examine the use of reflecting x-ray telescopes in two aspects. On the one hand, the reflecting optics makes it possible to have a comparatively large collecting area with small detector dimensions, which decreases the technical difficulties to a considerable extent and increases the signal-to-noise ratio; on the other hand, reflecting objectives open up the possibility in principle of obtaining an image analogous to that provided by telescopes in the visible region of the spectrum.
