X-ray delivery: stable and flat over 250 pulses per train. 1.1 MHz with 400 uJ

Optical laser delivery: NA

Achievements/Observations:

  • Beam optimization and characterization
    - Short pulses tuned
    - HIREX setup and used to characterize the number of SASE SPIKES per pulse (~10)

Issues

  • 10 SASE spikes per pulse is more than desired
    - discussion with BKR and AccRC regarding possibilities for optimization (feedback in the morning)
    -HIREX data proc is not correct as dark processing fails

    - DOC informed and working on it
    - one issue was gothard II appeard to have timed out - does the number of triggers need increasing?
    -sample jetting setup

    - electrospray working but saw exactly 1 hit in run 32
    - tried to alighn with silver nano-cubes but had to switch to sucrose to increase hit rate to aid alignment
    - no hits with sucrose seen with scanning X +- 1mm
