Figure 2
Beamline flux as a function of photon energy. Below 2.0 keV, calculated values for the 400 lines mm−1 (green) and 1200 lines mm−1 (red) gratings are displayed. In this energy range, the first harmonics of the U50 undulator structure (below 0.8 keV) and of the U28 structure (above 0.8 keV) are used. The curve above 2.0 keV (blue) shows the flux measured with the Si(111) reflection of the DCM and a calibrated photodiode in the second experimental station. For the undulator, the U28 structure with harmonics ranging from third (at ∼2 keV) to 25th (at ∼16 keV) were used.
