Subject: Shift summary 

X-ray delivery

  • 12.4 keV 200 pulses / train, relatively stable intensity ~1.2 mJ / pulse

Optical laser delivery

  • 420 nm PP laser
  • ns laser for jet imaging

Achievements/Observations

  • NKB focus checked and defocused to have about 3um(H) x 6um(V) beam
  • Collected a few hours data with PP laser on both jet and nozzle excitations (AGIPD in adaptive gain mode)

Issues

  • IRU Chamber LED was ON until 2:51am 
  • Nozzle damage found after ~1 hour measurement 
  • Hit rate seems too low still (less than 1%)
  • Nozzle exploded close to the end of the shift
