X-ray delivery

  • 7.8 keV, up to 260 pulses at 1.1MHz, ~3 mJ

Optical laser delivery

  • PP laser, stable delivery

Achievements/Observations

  • NKB focus optimized with reduced PSLIT (both MKB and EHU) opening
  • Found the orgin of the BG (mostly from AGIPD gun shield)
  • Stable AGIPD operation

Issues

  • Beam slitting with PSLITs & IRU_SLITs does not help in reducing the BG from the AGIPD Gun-shield
  • Placing additional Pb shield on the injector tip does not help (BG source is in between injector and AGIPD)
