Figure 4
Testing of the integration algorithms for finite rocking angles. (a) Convergence plot for the screw-dislocation test case at $[\phi]$ = 300 µrad. (b) Spatial profile of the scattered beam as a function of rocking angle. (c) Transmitted beam in a cross section of the crystal at $[\phi]$ = 300 µrad. (d) Scattered beam in a cross section of the crystal at $[\phi ]$ = 300 µrad. (e) Integrated rocking curve of the dislocation test case overlaid on the same curve calculated for a perfect crystal and the angular spectrum of the incident beam.
