Formation technology of X-ray quasimonochromatic fluxes with nanosize width and small angular divergence

The phenomenon of X-ray fluxes waveguide-resonance propagation is presented briefly. There is described simplest design of the planar X-ray waveguide-resonator (PXWR) - device functioned in frame of the phenomenon. Advantages and drawbacks of the device are discussed in details. Experimental characteristics of the composite PXWR that decreased the angular divergence of its emergent beam at the integral intensity conservation are presented. A simplified model of the functioning of this device is formulated.
