End of in-house beamtime

X-ray delivery

• 9.3 keV, 2.2-2.5 mJ pulse energy, up to 202 pulses at 0.5MHz, stable over the week

Optical laser delivery

• PP laser used but several issues with experiment master switch

Achievements/Observations

• Collected SFX data from deoxymyoglobin crystals mixed with an oxygen cage compound before illumination with the PP laser to release oxygen

SPB/SFX shift summary inhouse experiment 9456, shift 16./17.06.2025

**X-ray delivery**
- 6.51 keV, 1.4 mJ, 352 pulses/train at 1.1MHz rep rate

**Optical laser delivery**
- none

**Achievements/Observations**
- collected data on Ag cubes with two x-ray beam profiles
- tunnel CRL (Arm 1) increased intensity in focus by 30-40% (max intensity in NKB_focusing scene)
- collected data on gold spheres and encapsulin together from the double flow nozzle 

**Issues**
- beam trip due to vacuum spike in OH (PSLIT section)
