Figure 2
X-ray interference pattern from a boron fiber. (a) Intensity distribution acquired with the X-ray camera placed at a distance of 5 m from the point of intersection between the boron fiber and the 12.7 keV X-ray beam. (b) The cross-section of (a) (red) and the predicted intensity distribution for an effective source size of 35 µm (black). X-ray intensity (in arbitrary units) is measured as a function of distance from the core of the fiber. The experimental profile was obtained by averaging over ten pixel columns [red line in (a)]. (c) shows a magnification of the rectangular inset in (b). |
