An X-ray image and rocking curve maps of a reference silicon crystal in the 531 Bragg reflection. (a) An X-ray image at the peak of the crystal-integrated rocking curve. (b) A color map of the Bragg reflection angular widths (FWHM) and (c) a color map of the center of mass (COM) of the Bragg reflection angular dependences. All color maps presented in the paper are calculated with binning number N = 10. The contrast observed in (a) is mostly due to wavefront distortions in the beamline Be window (see Appendix B). |
