Figure 2
Flux at the sample position for the X-ray beam focused with the toroidal mirror M1 and monochromated by the W/Si multilayer. The beam size at the focal position is about 300 µm × 500 µm (h × v). The decrease towards small energies is due to absorption in air (about 300 mm air path), and the dip at around 12 keV is due to the W L absorption edges of the multilayer.
