X-ray delivery

  • 9.3 keV, 1800 uJ pulse energy
  • 1 - 202 pulses at 564 kHz

  • Poor beam stability overall. Lots of intensity fluctuations and rather long time to recover after change of number of pulses in any beamline.

Optical laser delivery

  • 800 nm, 113 pulses, 564 kHz stable delivery

  • Illumination laser aligned

Achievements/Observations

  • Aligned instrument

  • Prepared illumination laser
  • Shot PCS sample for a few minutes

Issues

  • PCS sample clogged (at filter not nozzle) after a few crystal shots

  • A few clogs with nozzle with lyzo, when X-ray were on, even far from the nozzle somehow the splash from the explosion grew on the tip
