Figure 3
Two schematics showing the geometry of the diffractometer and its parameters for measurement. (a) The diffractometer configuration, similar to a two-axis diffractometer, and (b) a side view of the configuration from the sample to the detector, and the machine parameters (X, Y) of Bragg spots with their equivalent angular parameters (2[theta]B, [chi]d) in an image data frame (the detection area) of the area detector.  [article HTML]
