The experimental background and the model description for the waveguide-resonance propagation of X-ray radiation through a planar narrow extended slit

The work is devoted to the experimental investigation of special features of X-ray flux propagation through a planar narrow extended slit at its parameter variation and is devoted to the model description of those peculiarities. It is shown that mechanisms of the direct flux propagation and the multiple total reflection of CuKα dominate for wide slits (>3 μm). On the contrary, for supernarrow slits (<0.1 μm), the X-ray flux spreads by the waveguide-resonance propagation. We called this waveguide-resonance unit the planar X-ray waveguide resonator (PXWR). Our experiments showed that, in conditions of X-ray waveguide-resonance propagation, a partial angular tunneling of the radiation flux in a gap between two PXWR placed one after another is observed. Based on the tunneling effect measurement, a hypothesis was proposed that X-ray flux can be manipulated by an external influence on the interference field of a standing wave initiated by the flux. The ways to upgrade the waveguide resonator are discussed briefly. Various fields of the efficient and practical usage of the waveguide resonator are pointed out.
