X-ray delivery

• 7.8keV, 2.4mj, stable delivery, homogeneos intra train energy most of the time.

Optical laser delivery

• ns laser for particle imaging

Achievements/Observations

• AGIPD BG optimized by opening Q2 & Q4 quadrants a few pixels and adding Pb shield on IRU_SLIT4
• NKB focused optimized
• Data (75 nm Ag cube) and gas BG (no sample) measured with two different gases (N2 and He)

Issues

• AGIPD BG near the center (1-2 pixels) were quite strong even with tight sliting, but issue solved by opening two quadrants (Q2 & Q4) and moving CSS about 1-2 pixels (elog:12731)
• Found additional AGIPD BG in Q2M1 module (mid-Q range), but issue solved by adding Pd shield on IRU_SLIT4 (elog:12734)

Instrument status

• AGIPD HV off.
• AGIPD gate valve closed and pinned.
• Attenuators set to thickest diamond.
• Vacuum valves closed.

To do for next shift

• Check focus and slit position and continue the program (data measurement).
