X-ray delivery
1-352 pulses at 10 keV, 1200 - 400 uJ.
Significant pulse energy slope within the train. Action on the kickers was eventually
performed leading to some reduction of the slope, though remaining still far from ideal. Decision to take the action took a very long time (2.5 hours).

Goal Achieved.
- Finished flat field measurement for AGIPD at different scenarios for upcoming user experiments.
- Aligned the spectrometer at DES and obtained the energy spectrum of 9 keV SASE. |

check of the optimized focussing options at 10 keV using only one arm in CRL2 - results still to be evaluated
successful check of the mirror chamber in the experiment hutch of MID - it was possible to reflect the direct beam down and use it under a shallow
angle on the sample position |

Beam conditions:
Used photon energies between 6 and 7 keV, including short undulator scans
Continuously got 1 mJ despite the short pulse mode
that's running
Bandwidth was found to be 18 eV FWHM at 6.07 keV (0.3%) by monochromator scan against fixed undulator setpoint
