Crystal mosaic physics

WebTechnically, the PST is achieved by a rotating disc carrying mosaic crystals on its circumference. Here a new analytical framework to describe the Bragg reflection of a divergent polychromatic beam from a moving mosaic crystal is discussed. Results obtained using this framework are compared with detailed Monte Carlo numerical simulations. WebTo go further, the mosaicity is defined as the full width at half maximum (FWHM) of diffraction peaks and it is an intrinsic property of each crystal affected by the hydrodynamic and mechanical...
