Preparation for user expt #7944

X-ray delivery

• since pulses (10 Hz) at 9.3 keV, 3 mJ
• Pointing stability 55 um RMS in the horizontal plane on FXE PI, which is lower as compared to earlier values

Achievements/Observations

• Aligned xrays into FXE vacuum/cryo setup
• Performed ice depositions in-situ and characterized by Xray

Handover

• Beam transport to SPB and 11 keV recovered
• We left Hirex inserted during FXE operation, but closed the GH2 shutter. It is still closed.

Issues

• XTD2 crl lens3x motor moving in wrong direction and already past all limits. Created ticket with EEE (no DOC available) #216784. Lens3x is not needed for the ongoing experiment, but the situation is potentially dangerous.
