X-ray diffraction and imaging

Several ways of tuning a higher asymmetry factor (>10) in V-channel X-ray monochromators, for metrological and imaging applications, were analysed. A more than sixfold intensity increase for compositionally and thermally tuned cases was achieved.

The reflectivity in Laue geometry of crystals bent by surface damage has been measured at 17, 59 and 120 keV X-ray energy. Despite the presence of a damaged zone several tens of micrometres deep, the crystals behave as self-standing bent nearly perfect crystals and are proposed as optical elements for focusing hard X-ray beams.
