Agenda
No meeting room. Call in, or come to Dave's office.
General
- Unblinding: Run 2 complete by December of this year?
- Last meeting: let's see how ACCUM/SCALER ratio looks before committing
- This meeting: ACCUM/SCALER results cause for concern?
- Rootfiles for the runs 23677 - 23764 missing (these had a different laser period)
Electron detector
- ACCUM/SCALER polarization comparisons
- Initial comparisons of polarization and aggregate rates: DAQ & Analysis log 313
- Aggregate rate comparisons with background (noise) subtraction: DAQ & Analysis log 314
- Application of deadtime corrections?
- Beam energy: what to use?
- ARC measurement ~ 1158 MeV (~ 1 MeV higher than Teifenback)
- What's the sensitivity of the polarization extraction? Erik found small numbers for fixed COmpton edge analysis (0.07%/MeV) Edet log 407.
- Run 1 analysis
- Remaining items on big uncertainty table (helicity correlated positions and angles, etc.)
Photon Detector
- Analysis updates
- Pedestal extraction progress (complete?)
- DAQ updates
- Simulation
- Analyzing power for different detector shielding configurations
Laser
- N/A
