Agenda

  1. PREX-2 runlist spreadsheet: [1] Github repo
    • There were a few runs that Cameron still hadn't changed from needs cuts, but that was because they had required some custom tuning of burp/stability that changed after the burp bug was fixed. He wasn't sure how best to deal with them yet.
    • I think we should go ahead and move forward without worrying about tweaking cuts yet. Respin1 will give us a survey of all the runs, and we can reconsider changes that might go in for a respin2
    • As we do the respin, the RCDB will have a new comment field that we can use to describe changes based on respin analysis
  2. Tao : additional combined plots looking at statistical self-consistency Git-repo
  3. Weibin and Tao: table of cuts. [2]
    • I think we're basically ready with the cuts.
  4. Robert: pedestals
    • He had raised a question on slack about uncommited files on the adaq cluster
    • Need to check on the blinded PMT and stubby test runs
    • There are some single-run channel maps for the beamline; Caryn thinks they may be PITA scans. We should check
  5. Victoria: beam modulation (raw data quality, residuals)
    • Paul will work with Victoria today to get the belssed slopes brought in as new corrector definitions for the respin
  6. Devi: blinded tubes
    • Devi will get beam-off pedestal files ready for all of the blinded-tube runs.
    • Last week, he had shown a discrepancy between the yield ratios and the asymmetry width changes between normal and blinded-pmt runs. He looked at the event signal distribution in HAPPEX Log 3935. Need to check for overflow events
  7. BCM & DD resolution; stripline and cavity and complementary bpm resolution and performance.
    • Yufan and Devika are working on these together; Devika is focused on BPM resolution, and Yufan is on the BCM resolution
    • Devika is looking at the 4A abd 4E normal and complement BPM resolution and combinations of them
  8. Overloaded regression (Tao?)
    • The overloaded regression has been set up on the ifarm
      • Std: five beam monitors as variables
      • Overloaded: All BPMs in the hall line
      • "Dithering Energy": 4A, 4E, and the dithering-based combination of 11 and 12 for energy
    • The Langrange analysis first pass is also set up on the ifarm machines; once respin1 is done we would be able to evaluate stable slope periods for Lagrange analysis similar to the "belssed slopes" for dithering
  9. Multiplet plots: haplog3936
    • The 50uA plots have broad tails. Is that dues to beam current cuts, or something else? Actually, when the single arm runs are excluded, the tails drop
    • Dithering distributions have large tails for both 50uA and 70uA running. Maybe this is coming from slugs where dithering slopes have a transition in the middle of the run?
    • Next would a set of left-arm and right-arm plots for all runs when those arms are working.
