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 |

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. |

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).

At 21:29:20 today, the number of bunches in SASE1 was increased from 1 to 352 without intervention of the SPB/SFX shift crew. 30 seconds later, the number
of bunches was reduced to 1, again without intervention from the SPB/SFX shift crew (see attachments 1 and 2).
We were in the middle of a measurement at that time and the sudden increase from 10 mW to 3.5 W average power resulted in the destruction of |
