Figure 3
Geometry related to CS movements. Illustration of one Debye–Scherrer cone and a misaligned slit. The Debye–Scherrer cone is diffracted by a thin powder sample illuminated with a narrow beam. The direct beam is along the x-axis. For a given angle η the misaligned ring in the CS selects the direction SM′ instead of the beam direction SM leading to an angular offset of δ2Θ with respect to the Debye–Scherrer cone.
