X-ray delivery
9.3 keV, 1.8 mJ, 202 pulses most fo the day. Pronounced (~30-40%) slope across the train.
Pointing initially far off the reference
crosshair. One hour required at the start of the shift to go to 9.3 keV and align the beam to the crosshair.

X-ray delivery
9.3 keV, 1.6 mJ, 202 pulses msot of the day.
Slope across the train reduced comapred to yesterday, now about 25%.
Changes
in number of pulses in SASE3 not always automatically picked-up by kickers adaptation and requiring a nudge from BKR to restore performances.

X-ray delivery
9.3 keV, 1.4-1.8 mJ and 12 keV, 1.1 mJ. 202 pulses most of the day.
Reduced slope after afternoon tuning, down to 20%.
Change
to 12 keV with file prepared earlier this week did not work (no lasing). Tuning to 12 keV took 40 minutes.
30 minutes downtime in the morning.

X-ray delivery
9.3 keV, 1.8 mJ, 202 pulses most of the day.
Attempted tuning to 14.8 keV during the first hour fo the shift did not work
out. More time will be spent tomorrow morning tuning to that photon energy.
Overall stable delivery. Only a magnet failure at 20:25 resulted |

10.7 keV, up to 339 pulses at 1.1 MHz.
Large slope through the train, up to 70% with 339 bunches. BKR was not able to find
the cause so far, we agreed to pursue this further tomorrow.

Slope reduced at the start of the shift. Approximately 20% slope
after that with the patterns used for data collection today.
