Typical intensity distributions on a two-dimensional X-ray detector behind the CS for a misalignment between the CS and the Debye–Scherrer cone. (a) The CS is not aligned along x. Projected onto the X-ray detector, the ring of the CS is smaller than the Debye–Scherrer cone. Only for a small range around the angle η is the Debye–Scherrer cone seen on the screen. (b) The CS is aligned along x. Parts of the Debye–Scherrer cone are seen at the angles η and η + 180° due to a misalignment of the orientation and the transversal position (yc and zc) of the CS. |
