X-ray delivery

  • 6 keV, ~3.0 mJ, stable delivery

Optical laser delivery

  • ns laser for particle visualization

Achievements/Observations

  • measured 1 sample roughly for 9 hours (hit rate went down in the afternoon)
  • Julabo chiller (AGIPD) is still on target (-32 degree)

Issues

  • NKB mirror drifted in vertical direction: it was optimized again at around 9pm
  • extremely low hit rate even with sucrose (extremely few particles were observed in sidemic, 1 particle within a few seconds): maybe the aerodynamic lens should be cleaned
