Figure 6
Repeatability of the area detector shown by means of (a, b) XRD patterns of LaB6 collected at short and long sample-to-detector distance (SDD), respectively, and (c) laser interferometer measurements of repeated back-and-forth movement with a total travel range of 20 mm within the detection range of the interferometer. Each inset scales up the data in intensity and relative position, respectively, to emphasize the corresponding small errors in diffraction angle and position. |
