Jiawei Waymo internship: 3 months over summer. Will resume this work after.

Progress

• Jiawei looked into specific nudge events
  • 4 examples
    • 2018-03-29/30: Beam spot change
      • Unknown why the beam spot was changed
      • Before and after scalar ratio values are different... maybe the AMO had different beam current but not updated. Maybe fitter issues
    • 2018-03-05: Long accel down
    • Run 71350/71351: David failed to restore spectrum
    • 2022-06-25: Cristiano nudge
      • Mysteries abound: no 3 plateaus in beam position. Spectrum looks odd. Seems that there were 3 nudges and the edge dropped 60 MeV
      • We looked at Naomi’s nudge and there seems like little correlation before 12:18 but seems like strong PITCH to edge correlation
  • Todo: Take all nudge events, shuffle, take the first 10. Use that time with a +/- 5 min (or 10 min) window and make the Naomi plots.
• Naomi suggested maybe using PS pair energy instead of a microscope.
