Figure 4
Experimental images of the focus obtained at the beamline with a contoured crystal (filled squares) and with a rectangular crystal (hollow squares). Images (a), (b) and (c) correspond to Bragg-reflected beams centred at the Fe (7.112 keV), Cu (8.979 keV) and Ge (11.103 keV) K-edge energies, respectively. These diagrams point out the effectiveness of contour tailoring, especially at high energy. |
