Figure 10
Longitudinal positions and sizes of the KB vertical and horizontal foci before (a) and after (b) the alignment in zero-order monochromator operation. The insets show the shape of a single-shot imprint as an example. Measurements were carried out at 13.5 nm. The maximum FEL pulse energy was ∼100 µJ but has been attenuated to 10–0.5% transmission during the measurement series. Further details are given in the text. |
