X-ray delivery
1-350 at 12.45 keV, 1700 uJ. Stable delivery

Optical laser delivery

None

Achievements/Observations

- collected data at different delay times 14s and 18s with over 7 hours of data collection
- the jet was stabilized again by removing the catcher and decreasing transmission to ~30%
- removing the catcher is critical to get stable jet, that allowed us to run for over 20 runs without stop.

Issues

- The jet was extremely unstable for 1.5 shifts; we needed to stop the runs intermittently with intervals less than 10 mins. 
- It seems difficult in principle to go for longer delay times with the current setting; may be elongating the distance in Y-axis with 400 pixel if the jet stable may help to reach 20s.
