Shift summary
X-ray delivery
9.3 keV, 2000 uJ pulse energy. Beam was unstable at the beginning.
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 GV for ~ 2 hours
Issues
PSI from the first reservoir was leaking
Concentration of PSI seems low (judged by seeing camera for liquid jet delivery).
We could not see any diffraction from PSI by both AGIPD preview and OnDA (same setting with GV used)
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
