Khlopuzyan}, howpublished={online}, abstract={In order to obtain monochromators and lenses with controlled parameters in the hard X-ray range (above 30 keV), we have considered the X-ray diffraction in Laue geometry influenced by the temperature gradient. It is shown that with the help of the temperature gradient impact it is possible to separate a beam with high angular and spectral width from a white beam, transfer it in the direction of reflection and focus it, i.e., control the parameters of the beam in a large range.}, title={FOCUSING OF HARD X-RAYS IN A QUARTZ CRYSTAL UNDER EXTERNAL TEMPERATURE GRADIENT}, type={Հոդված}, keywords={Physics, Atomic and molecular physics, Materials science}, }
