Measurements to check the impact of bunch compression on FXE mono transmission were successful. We could change the peak current between 4 and 12 kA and saw changes in bandwidth between 17 and 100 eV (at 14 keV). Results are under evaluation.

SA1 brought to safe state:

• CRLs moved out
• Mono moved out
• CVDs in XTD2 ATT inserted
• PBLM-based feedback was started and kept running to avoid beam drifting off of M3
• Hirex shutter closed
• The M1/M2 offset was decreased a bit as compared to saturday mornings' value (was very close to total reflection limit and to safely use 100 bunches, it was decreased to be on the safe side). Should not affect further measurements for XFELO on sunday.
