Figure 11
Spiderweb slits are used to select diffraction from either a nickel or ceria reference powder, both in the direct X-ray beam and 6 mm apart. (a) Diffraction intensities for three positions of the spiderweb slits. (b) A top-down view of (a), for a z-scan with 0.5 mm increment. The nickel selection at z = 0 mm is shown on the top of the graph, while ceria selection at z = 6 mm is shown on the bottom. Arrows at the top of (b) indicate the diffraction peaks from nickel, while arrows at the bottom indicate diffraction peaks from ceria. |
