AIOP Meeting Notes - 11/18/24

Attendees: David, Thomas, Torri, Naomi, Armen, Jiawei, Patrick

Note: With the holidays approaching, some work may need to be conducted through alternative means.

Progress Updates

Thomas

  • Will run queries to retrieve data on nudges again.
  • Plans to search for relevant anecdotes in the logbook.

Patrick

  • Shared slides on his investigation into backlash:
    • Used S2020 and removed outliers.
    • Ensured the beam was operational.
    • Observed fixed roll and three groupings of yaw:
      • Coherent edge spread (a few hundred MeV).
      • Question: Where is this spread originating?
    • Hypothesized that variation could be fit-driven:
      • Scalar values archived:
        • Requires refitting (current fits show errors).
        • Utilized Minuit fit.
        • Possible hue mismatch with run number (or another factor).
        • Need to calculate the error on the coherent edge.
      • Highlighted the difference between set point and position.

Naomi

  • Researched coherent peak movement instances:
    • Recalled the March 30, 2018 event, where the coherent edge appeared problematic:
      • A new diamond spot was located with a very narrow width.
      • After the accelerator resumed operation, the width increased significantly.
      • Hovannes relocated the beam to a new position for stability.
    • Plans to examine CPP logs for periods with significant beam movement.

Jiawei

  • Presented before-and-after plots of coherent peak changes using archived data:
    • Data source: HD:CBREM:ENH_REF.
    • While the reference plot appears static, it successfully illustrates the difference in coherence.
    • Mentioned that a “live plot” is harder to implement but feasible.

Action Items

  • Thomas: Follow up on nudge data and search for relevant logbook entries.
  • Naomi: Continue analysis in CPP logs for beam movement.
  • Patrick: Refine Minuit fit and further explore causes of variation in coherent edge spread.
  • Jiawei: Investigate feasibility of implementing a live plot for coherent edge monitoring.
