(a) Attenuation in the phantom of 0–11 paper layers plus a Lucite rod of diameter 10 mm. The thin broken lines indicate the bands where curves in (c) and (d) were calculated. (b) Top image of the phantom with intensity curves across the rod: experiment (left) and calculation (right). (c) Transmitted intensity (thin line), non-scattered portion ξ (thick line) and refraction angle (broken line) along the horizontal band in (a). (d) Transmitted intensity (thin line), refraction angle (broken line) and portion of the non-scattered beam (thick line) along the diagonal band in (a). For the pseudo-Voigtian fit (21) the full data set of 33 points between −12.5 µrad and +11.0 µrad are used. |
