ADVANCED MATERIAL FOR REFRACTIVE X-RAY OPTICS
The estimation of the various elements and substances for their potential use as optical materials in the compound refractive lens was made. It is shown that in the geometrical optics approximation for the different x-ray energy ranges could be selected materials, characterized by the best combination of refractive and absorptive capacity. The possible options for the practical use of advanced materials in creation of the new types of x-ray devices are presented.
