Figure 1
Experimental reflectivities (solid curves) of C-coated (a), B4C-coated (b) and Ni-coated (c) mirrors versus the soft X-ray photon energy at three different grazing angles θ = 0.6° (1), 1.2° (2) and 1.8° (3). Dashed curves were calculated without a fitting procedure with the use of the atomic concentration profiles shown in Figs. 3(a), 4(a) and 5(a). Arrows indicate the position of the boron, carbon, oxygen and nickel K- and L-edges of absorption. |
