Subject: Shift summary 

X-ray delivery

  • 10.65 keV, 128 pulses at 1.13 MHz, 1.6-1.7 mJ.
  • Overall stable delivery.

Optical laser delivery

  • 800 nm, 50 fs, 226 pulses at 1.13 MHz.

Achievements/Observations

  • Continued characterisation of crystals (thermal measurement, interferometry, imaging) under different beam conditions ranging from direct to focused beam.
  • Spectral measurement in parallel to crystals characterisation.
  • Imaging of static samples with Zyla and Shimadzu.

Issues

  • We were not able to complete the last part of our programme since we were not allowed to change the number of bunches and repetition rate. Measurement ended at 21:00 and last two hours fo the shift were spent in discussion with SQS/BKR/RC/PRC with no positive outcome.
