Abstract
Perfect crystals with asymmetric surface cut were studied to evaluate their influence on the coherence of x-rays. An analysis of single- and double-crystal setups in both Bragg and Laue geometries is presented. The Bragg case was studied experimentally. The experiments were performed at Optics Beamline BM5 of the European Synchrotron Radiation Facility. A virtual source created by an asymmetric crystal was probed using an interferometry technique based on fringe analysis, which were produced by boron fiber. The conditions required to preserve coherence in a double-crystal setup are obtained theoretically, and proved experimentally in case of Bragg diffraction.
