X-ray delivery

• 9.3 keV, 1400-1600 uJ pulse energy, ~1000 uJ for 10 minutes

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

• Installed new YAG and powder capillary
• Measured GV from defocused beam for 5 runs (run 6-10) and focused beam for the rest of the beamtime (run 11-24, 28-42). In total 34 runs (170 minutes)
• Hit rate with focused beam and high sample flow rate (15 sample, 15~20 EtOH) : ~0.02~0.03 %$
• Hit rate with 3ul/min sample + 3ul/min EtOH : ~0.08 % with this sample

Issues

• After take new darks for HIREX, the intensity was too high so BIG BROTHER was intervened. Solved by change filter from Al_1.1 to Al_1.2.
