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)
