Shift summary for 2024-02-25 from 11:00 to 2024-02-25 at 14:00:

Self-seeding at 8.5 keV, with approximately 500 μJ per pulse. 

Overall, the performance of x-ray self-seeding remains good, and users are happy. Pointing stability is also exceptional. However, enhancing photon energy slightly (600 uJ as we had yesterday) would further improve the signal-to-noise ratio.

Key Achievements and Current Challenges:

  1. Ongoing data accumulation.
  2. Issue with the sample motor (stepper motor). The encoder ceases to update values although the motor is actually moving. While a temporary workaround has been implemented, a thorough investigation is needed post-beamtime. More details: [Link]
