Shift summary for 2024-02-24 from 07:00 to 2024-02-25 at 14:00:

Self-seeding at 8.5 keV, with approximately 500 μJ per pulse. Following re-tuning around 10 am on the 25th, the energy per pulse increased to around 600 μJ.

The x-ray intensity and pointing stability have been excellent, resulting in a substantial amount of data being acquired by users just two days into the beamtime. Users have expressed satisfaction with the performance thus far.

There were a couple of brief beam downtimes, but they had minimal impact on beamline operations.

Achievements:

  • Successful laser delay scan (0 - 1000 ps) of wire compression dynamics under ultra-intense laser interaction (>10^21 W.cm-2).
  • Nanofocus Z scan imaging completed.
  • Online analysis tools (DAMNIT) are functioning properly.
  • Some minor issues with the automatic shot procedure using MDL were encountered but mostly resolved.
  • Ongoing issues persist with the off-axis-parabola mirror X axis (motor movement not stopping), which will require follow-up after the beamtime.
  • A minor issue was identified with laser timing jumps, possibly stemming from a trainID distribution issue with the ToD system. Increasing the sequence delay of the master timer from 10 to 30 appears to have mitigated this problem.
