X-ray delivery

  • 9.3 keV, 1.4-1.8 mJ and 12 keV, 1.1 mJ. 202 pulses most of the day.
  • Reduced slope after afternoon tuning, down to 20%.
  • Change to 12 keV with file prepared earlier this week did not work (no lasing). Tuning to 12 keV took 40 minutes.
  • 30 minutes downtime in the morning.

Optical laser delivery

  • NA

Achievements/Observations

  • Optimised slits to protect the nozzle from X-ray damage.
