X-RAY FOCUSING BY THE ZONE PLATE IN LAUE GEOMETRY

The experimental results on diffraction of a spatially inhomogeneous x -ray beam made in the Laue geometry are presented, A diffraction lens with a full aperture A = 168 mum, number of zones N = 23 and gold coat ing thickness t(Au) = 1.5 mum was fabricated to modulate the incident beam at the crystal entrance surface and focus the diffracted beam at the exit surface. A numerical simulation of the obtained image was pro duced and comparative analysis was carried out.
