*********NEW BLUEJEANS CALL-IN INSTRUCTIONS*********
----------------------------------------------------
1. Dial Toll-Free Number: 1-888-240-2560 (U.S. & Canada)
2. International participants dial:
Toll Number: 1-408-740-7256
3. Enter meeting ID: 831693292

Agenda

No meeting room. Call in, or come to Dave's office.

General

  • Collaboration meeting 2 weeks away
  • Goals for meeting discussed at July 9 meeting:
    • Electron detector
      • Resolve discrepancy between runlet-based and laser-cycle based analyses
      • Assign final uncertainty for dead time/strip efficiency/trigger logic catch-all
      • Start to address remaining "small" sources of uncertainty
    • Photon detector
      • Updated comparison of photon det. and electron det. (time dependence)
      • Show updated "absolute" polarization (?) with new analyzing power
  • Presentations: who will be attending meeting and wants to speak?
    • DG will present Moller
  • Meet again next week?


Electron detector

  • Runlet vs. laser-cycle based analyses
    • Run-by-run comparison - AN fit to asymmetries: Edet elog 608
    • Run-by-run comaparison - AN fit to laser-cycle, VT fit to runlet-based: Edet elog 609
    • Run-by-run comparison - AN fit to runlet-based asymmetries, VT fit to runlet-based, refined set of runs Edet elog 610
  • Modelsim Updates (any?)
  • Application of deadtime (from Modelsim) to data
  • Comparison of asymmetries from scalers and accumulators (time-dependence over whole Run 2)
  • Run 1 analysis
  • Remaining items on big uncertainty table (helicity correlated positions and angles, etc.)

Photon Detector

  • Analysis updates
    • Pedestal extraction progress Plots
  • DAQ updates
  • Simulation

Laser

  • N/A
