In the promising framework of coherent x-ray scattering, the use of hard x-rays of energy in the few keV range has not been developed as far as its soft x-rays counterpart, in particular at large diffraction angles. The increased difficulty compared to soft x-rays and small angle scattering arises mainly from a smaller coherence volume at higher energies and a rapid smearing of the contrast at large diffraction angle because of an optical path length difference that increases beyond the longitudinal coherence length.
A special setup was developed on the ID20 Magnetic Scattering beamline at ESRF to perform coherent scattering experiments at large diffraction angles up to 75° in Special care was taken to lessen the number of windows in the x-ray path. A secondary source was defined by means of a set of slits placed 3 meters away from the collimating pinhole. The size of the source was adjusted so that the transverse coherence length would match the size of the pinhole. A monochromatic undulator beam from a double Si111 monochromator was used and a total coherent flux of 3109 ph/s at 190 mA ring current through a 10 m pinhole was obtained at 8 keV.
Poster Abstracts

The recent development of experiments taking advantage of the partial coherence of the x-ray beams produced by high-brilliance low-emittance x-ray sources has naturally stimulated the development of new optics. For techniques based on phase contrast imaging, severe requirements on the wavefront distortion are indeed necessary for being able to retrieve information on the sample under study. In the case of tomography, it was shown
1 that, a multilayer with an energy resolution one to two order of magnitude that of a perfect crystal would make an ideal optics, providing it could conserve the homogeneity and the coherence of the beam.
In this presentation we report on our effort to improve the quality of multilayer mirrors in terms of coherence preservation. The quality of the mirror substrate turned out to be the key factor since multilayer coatings would generally mimic the substrate surface. In principle, the mirror surface slope errors should be smaller than /2, representing the angular source size However, the progress in mirror technology is constantly challenged by the advent of better sources. For a substrate with a given shape error the phase distortion of the wavefront increases with the beam incidence angle. This was demonstrated by imaging a series of multilayer coatings (W/B4C, Ru/B4C) with different d-spacing made on substrates of same quality. Recent results on a 300-mm long silicon mirror coated with a 4nm (Ru/B4C)80 multilayer are also presented. The slope error was measured to be around 0.2 µrad. The quality of the bare substrate and of the multilayer-coated substrate was assessed by a number of means, including the Talbot imaging and hard x-ray shearing interferometry2 techniques.
