(a) Simplified geometrical construction of the different contributions to peak broadening of reflections on the area detector. In the calculation, all parameters are expressed in terms of the diffraction angle 2θ, the respective sample-to-detector distance SDD, the given sample dimensions and beam height. (b) Individual contributions to peak broadening and the Gaussian convolution according to equation (1) for a given measurement geometry (sample-to-detector distance 387 mm, capillary diameter 0.57 mm). |
