General

• This meeting will focus on short-term tasks and goals
• References for discussion (collaboration meeting talks):
  • Edet/overview: pdf
  • Photon detector: pdf

Electron detector

• Run 2 analysis issues
  • Find/analyze missing runs (23674-23764) - why missing? Are there more?
  • Understand behavior near run 24000 - nothing strange going on?
• Need to work on generating polarizations for Run 2
  • Find appropriate way to scale the Compton results - using info from Moller
  • Generate "constant" polarizations where appropriate - figure out best way to fit/describe periods when polarization changing rapidly
• Run 1
  • Latest iteration of root trees ok?
  • If yes - need to replay run 1, run analysis script over data
  • Systematic errors the same?

Photon Detector

• GEANT4/snapshot comparisons
  • Different approaches to getting analyzing power result in at most ~1% deviations
  • Given Juan Carlos' timeline for defending and other required tasks before then, should move on from simulation work and produce latest photon detector and edet comparisons

Laser

• N/A
