Agenda

Usual meeting room (L210A).

Miscellaneous

• Collaboration meeting coming up. Note from Mark Pitt:

This will be an important meeting.  We will be carefully assessing our
progress to determine how realistic our goal of putting forward an April
2014 invited talk nomination by the deadline of October is (the final
decision would be made at our October collaboration meeting).

Laser

• Haven't started measurements, but PC is working and filters have arrived.

Photon Detector

• Look at backgrounds via scalers - correlate with extracted asymmetries.
• Follow up from a couple weeks ago:
  • Few events that deposited more energy than the incident photon [1] --> any conclusions?
  • Checks using "default" GEANT routine for summing energy?

Electron detector

• Efficiencies from tracking mode data (accounting for angle of electrons on detector)
  • Efficiency from straight tracks: Edet log 532
• Effect of efficiency (at trigger level) on extracted polarization
  • Elog from last week: Edet log 531 --> need more statistics to get reasonable error estimate
