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

The cross on the FEL imager, which we use as a reference for BKR crew, is not centred on the GATT aperture. when was this changed, and why?
att. 1 and 2 show the current position (the saturated image aids the positioning of the GATT aperture).
att. 3 is from two weeks ago. then, the cross was centred on the GATT aperture. |

X-ray delivery
1 to ~332 pulses at 6 keV, 4.5 mJ
Stable delivery
Number of pulses limited by the Photon Beam Power local limit
that is set to 16 W. Is this intentional? All other limits are set to 40 W

*Achievements :
- Generally rather successful with very high quality beam parameters
- We had a nearly steady 800 uJ+ HXRSS flux during the user run and ~ 4mJ SASE during the setup at HED. |

| Like after the previous winter maintenance period, the shutter of FXE appears as opened in DOOCS panels even though it is closed (https://in.xfel.eu/elog/OPERATION-2023/58). |

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 |
