Fig. 4 The distribution of diffracting crystallites creates the appearance of diffraction peaks at different 2theta values. The different channels in the detector are each assigned a different 2theta value during a measurement. Crystallites diffracting at the same Bragg angle, but from different positions in the beam footprint, will be detected at different channels, which will be converted into a range of 2theta values. When the crystallite size is small, the distribution of intensity across the detector channels will be uniform and observed as a single broadened peak (top illustration); when the crystallite size is large, only a portion of the beam footprint will be diffracted and this will appear as separate peaks on the detector (bottom illustration)
