**X-ray delivery**
- 9.34 keV, 1200-1400 uJ pulse energy

**Optical laser delivery**
- illumination laser

**Achievements/Observations**
-  Managed to synchronize droplets for some runs, resulting in high hit, averaging rate ~ 8-10% and spiking up to 20%.

**Issues**
-  Synchronization and stable delivery  are challenging 
- Beam was down several times

**Instrument status**
- AGIPD HV off.
- AGIPD gate valve closed and pinned.
- Attenuators set to thickest diamond.
- Vacuum valves closed.
- AGIPD breaks engadged
- ns Lasers off
- HIREX  is handled by FXE, but maybe better to check in the morning
- PAM interlock on and shutter open
- Left the gas at 5 for 0 flow (and no noise) from GP13 flowmeter D, during the night it was at 0, and in the morning it was filled with air... Tonight we leave it this way and in the morning let us know if it worked or not.
