X-ray beam recorded with a CMOS flat-panel detector (C7942, Hamamatsu Photonics) at the sample position. (a) Overview of the expanded beam. The spot at the top left is part of the direct beam. The horizontal beam at the top is the beam reflected by the horizontal mirror but not by the vertical mirror, while the vertical beam on the left is one not reflected by the horizontal mirror but reflected by the vertical mirror. The large rectangular bright area is the beam reflected by both mirrors. The peak X-ray energy was 12.4 keV. The field of view is 52 mm × 45 mm. (b) Horizontal intensity profile of part of the enlarged beam.
