Agenda

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

General

• Goals to achieve by collaboration meeting (DG thoughts)
  • 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

Electron detector

• Modelsim Updates (any?)
• Application of deadtime (from Modelsim) to data
• Runlet vs. laser-cycle based analyses
• 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
  • Updated Pedestals vs Cycle Number
  • Sample Laser Off Cycle 16 Channel 19 Pedestal
  • Sample Laser ON Cycle 16 Channel 19 Pedestal
• DAQ updates
• Simulation
  • Estimate of analyzing power including effect of nonlinearity due to photon collection Photon log 270

Laser

• N/A
