Description
Summary:We present the design and instrumentation of a novel holography endstation for the P10 coherence beamline at PETRA III at DESY. The experimental imaging scheme is based on a highly coherent and divergent (cone) beam illumination, achieved by fixed curvature focusing mirrors with additional spatial and coherence filtering by x-ray waveguides. The optical elements along the beam path and the instrument under construction are described. Preliminary results obtained in a similar setting under comparable parameters are given as a benchmark, and first simulations of one of the two mirrors are presented to study the effect of imperfections on the field distribution in the focal plane.
