Possibilities of the use of polycapillary optics in x-ray astronomy

Abstract

Possibility of creating the x-ray telescope with use of polycapillary optics have been discussed during approximately ten years. However, only later this idea is getting reality owing to the improvement of manufacturing technology. Possibility of creating the telescope for a broad energy range is considered. For choice an optimal version of the telescope the experiments on transmission the x-ray beams of different energies through polycapillaries with channel diameters from 0.5 micrometers up to 30 micrometers carried out. As basic module the version of telescope with 100 sq.cm entrance area and focal distance from 1 to 2 meters is considered. For improvement of the angular resolution of proposes to arrange the polycapillary collimator with angular resolution of the order of 10-4 a radian before the telescope.
