Figure 4
The experimental reflectance curve (solid line) of the multilayer compared with the reflectance curve (dashed line) calculated by solving Fresnel equations. A Gaussian distribution with a 3.8 Å width is used to take into account the interface roughness. Also plotted here is the response of the 13-element Ge detector (Canberra Gl 0110) (dotted line) versus incident photon energy. The single-channel analyser (model 2031) was set to a center energy corresponding to 8.07 keV and an energy window corresponding to 8 eV. A model 2020 spectroscopic amplifier was used, with a shaping time of 1 µs. The incident beam had a bandwidth of a few eV.
