Figure 7
Diffraction from a circular pinhole of diameter µm, Å, detector with 22 µm pixels at 1.8 m. This image results from the accumulation of 2000 DI-CCD frames. For each frame, the CCD was transformed in a photon-counting detector, as described in Livet et al. (2000). Intensities correspond to counts, and the log units show the large dynamics obtained (unpublished results obtained at the ID20 beamline of ESRF). |
