Figure 5
Design of the in-line XUV split-delay and focusing optics. Shown are the FEL beam path, the split-mirror, the ellipsoidal mirror and the REMI with gas jet. Also depicted is the generation of a pump (blue) and a probe (green) pulse by translating the upper split-mirror along the mirror normal axis. Pump and probe pulses are temporally delayed by td. The figure is adapted from Schmid (2018). |
