Figure 4
Laue diffraction image for an NaCl spherical crystal integrated in ToF with (a) the double-layer WLSF detector and (b) the current SXD detector. In order to obtain the same reflections on both detectors, the sample was measured at a fixed position and rotated 37.5° anti-clockwise for the current SXD detector measurements. The two plots are depicted in a sketch to illustrate the geometry and positions of the two detectors on the SXD instrument. The angle α is defined in equation (1). The colour bars represent the ToF integrated counts on a linear scale. |
