Figure 15
FWHM of the measured diffraction peaks (blue dots) deduced from the data set shown in Fig. 13. The different contributions to the peak broadening are highlighted: incident photon spectral width (∼3 × 10−4, green), incident beam divergence (0.014°, magenta), crystallite size broadening (cyan), point spread function of the XPAD and the beam/capillary size (orange). The modelled resolution function (red curve) is calculated as a convolution of the various contributions. |
