Abstract

This paper discusses the design of the SODART multimirror x-ray telescope with grazing-incidence optics, which is being developed for the Spectrum-Röntgen-Gamma space observatory. The telescope has a transformable high-stability carbon-fiber-reinforced plastic design that can be deployed in space with monitoring and control of the size parameters, the temperature regime, and a mechanism for changing the focal devices. The large effective area of the mirror system, the objective Bragg spectrometer with high spectral resolution, and a complex consisting of eight focal devices included in the telescope make it possible to solve many problems of x-ray astronomy.
