X-ray delivery

  • 6.0 keV, up to 202 pulses at 564 kHz 1.3-1.8 mJ.
  • Decaying intensity through the day. Recovered once at 15:15 and slowly decaying again after that.

Optical laser delivery

  • 770 nm, up to 202 pulses at 564 kHz and 101 at 282 kHz.
  • Wavelength drift due to problem with BCC piezo stage. Mitigated by LAS.

Achievements/Observations

  • Collected time-resolved diffraction from gold and gold-platinum nanorods/spheres at multiple laser fluences.

Issues

  • Problem with the four ASICs in module Q2M1 of AGIPD could not be solved. Operated without those for today. Will be further investigated later on.
