X-ray delivery

  • 9.3 keV, 1600-1700 uJ photon flux, beam down once due to Big Brother intervention. But the signal on HIREX was less than 10 counts.

Optical laser delivery

  • ns laser for particle illumination inside the chamber
  • another ns laser to visualize the tip of capillary on top of the chamber

Achievements/Observations

  • Measured granulovirus

  • Hit rate of defocused beam was similar or less than with focused beam, Q range is smaller than with focused beam.

  • Without dryer, hit rate is more than twice.

Issues

  • BIG BROTHER is intervened due to HIREX and beam was down due to that. But the count on HIREX with Al1.2 was less than 100 count.

Instrument status

  • AGIPD HV off.
  • AGIPD gate valve closed and pinned.
  • Attenuators set to thickest diamond.
  • Vacuum valves closed.
  • AGIPD breaks enguaged
  • ns Lasers off
  • HIREX is out
