X-ray delivery

• 10.65 keV, 128 pulses at 1.13 MHz and 16 pusles at 141 kHz.
• Overall stable delivery.

Optical laser delivery

• 800 nm, 50 fs, 1-226 pulses at 1.13 MHz.
• A few issues with minor impact on operation this week. Detail communicated to LAS.

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 Bragg magnifier.

Issues

• DAQ configuration failing multiple times. Repeating the same sequence of actions yield variable results.
  • Several times with unhelpful message "Failed to execute "assign" action".
  • On one occasion with the message "Assignment for data-source/group 'SPB_CFEL_JF1M/DET/JNGFR09:daqOutput'/'SPB_CFEL_JF1M_9' not specified." even though we used this group before without any issues.
• JUNGFRAU 1M acquisition could not be stopped. Restarting control and receiver servers and associated devices resulted in the control device being stuck in INIT state. Detector had to be power cycled to solved the issue.
