Figure 3
Theoretical E/ΔE, including the spot size and diffraction contribution, as a function of photon energy. The three bunches of lines correspond to the three gratings (indicated on the right) and the individual lines within each bunch to variation of Cff by integer numbers (within the limits indicated on the left). The shaded bands display E/ΔE without the diffraction contribution, with their edges corresponding to the Cff limits of the bunches. The insert shows a typical spot at the exit slit. |
