Figure 5
The homogeneity of the detector at a photon energy of (a) 10 keV and (b) 5 keV in ultra-high gain mode and with Ethresh = . The raw data were preprocessed by binning 10 × 10 pixels into one in order to overcome the quantum noise in comparison with the inhomogeneous detector response. The ring in the centre is an artefact which comes from the positioning of the beamstop to the centre of the scattering pattern. |
