Figure 5
Examples of beam profiles with 2, 20, 30, and 38 CRLs inserted at 35.00 keV recorded with a beam viewer on the PXRD2D sample position (13.4 m from the CRLs). The top panels show the intensity distribution on a normalized linear color scale. The scale bars are 100 µm in all images. The images are magnified by a factor of two for every step from left to right (increasing number of CRL). The beam profiles below show the normalized intensity profiles either horizontally or vertically over the whole image. The gray shaded area shows the FWHM.
