Agenda:

  1. Previous Meeting
  2. Activities:
    • CPP
      • CPP Calibrations (Naomi)
    • Quantification of bad gain calibrations
      • Looking at initial results comparing traditional GCF compared to roboCDC GCF in progress
      • HVB Currents during initialization are not consistent with what we see during actual running, but are consistent with data from the HVBs from EPICS
      • Naomi identified why our model never learned anything useful from HVB current, related to the CDC alcohol swap between 2018 and 2020 run periods. This affects the gains. See also the data in these plots GCF_gasdensity that Diana's model used for training. GCFs vs gas density for 2018 and 2020 should not overlap.
      • CPP plans
      • CPP preparations
    • Grafana CDC dashboard
    • PrimeX Preparations:
      • In regards to the look back: HVB current will be fixed and ignored, so there really is no need for a look back for Primex.
      • Thomas added in auto-off for Empty Target runs
    • Capstone Students
      • Won't start until the middle/end of October.
      • Oct. - Dec. will purely be EDA and basic project understanding
        • 4 - 6+ hours of meetings to be expected in this timeframe
      • Really get going on the project in January.
    • FDC calibration
      • Reach out to Lubomir alternative FDC for cosmics- David.
      • 2020 CDC-FDC model results: CDC-FDC model slides
      • Potentially give capstone students FDC calibration model development
      • Discuss with Simon how useful FDC calibration constants are for physics analyses
    • Next steps
      • CLAS12 Polarized Targets
        • Update from James (8/25): concern about poor fits that give polarization (i.e. Diana's eventual target values). Can begin initial data exploration whenever we have time.
        • data from fits to obtain polarization AND relevant EPICS data are stored in json files located in /group/poltar/HallB/RGC and should be readable
      • **AIEC Auto Control Wish List:**
      • GlueX TOF
      • BCAL baseline (slides) - David follows up:
        • Do we need another sensor?
        • What are the limitations on existing sensor and logging of temp value?
  4. Workshops
  5. Talks/Presentations
    • Torri and Diana presenting at QNP (QNP)
    • Diana presenting at ACAT2022 (15 min talk + 5 min questions)
  6. Publications:
