Figure 7
(a) Experimental reflectivity curve $[I_{\rm R}(\Delta k)]$ collected for the (220) reflection at 12 keV in symmetric Bragg geometry with the 400 µm-thick diamond crystal. (b), (c) Intensity images collected with the detector placed at the vertical focus position of the incident beam for (b) a photon energy of 3 eV below the perfect Bragg condition, corresponding to point (1) in panel (a), and for (c) a photon energy centred perfectly at the Bragg condition, corresponding to point (3) in panel (a).
