Figure 5
(a) Image of the direct beam from the polycapillary at the detector on a log-scale. (b) Sum of the intensity across the detector. (c) Intensity of a vertical slice, out of the diffraction plane, at the middle of the fan. Each pixel is 172 µm and the FWHM of the fan in the vertical direction is 5.8 mm. The signal and background region, as described in the text, are shown. |
