摘要：

It is known that polycapillary half-lenses and lenses limit x-ray energy both in low and high energy area, i.e. they create an energy transmission range from 2 to 20 KeV. This enables use of the lenses as filters within a wide energy range. The effective transmission range for each x-ray optical system was determined. To obtain a monochromatic beam within a narrow energy range, the spatial collimation of x-ray beam by means of Kumakhov's half-lens and deflection it from a flat monochromator was performed. The block scheme of X-ray monochromator is described. Using the second half-lens, it is possible to focus monochromatic CuKalpha1 radiation. Such super-high monochromatization is required for phase analysis of complex structures characterized by low symmetry.
