Agenda

Usual meeting room (L210A).

General Analysis

• Word on the street is that the photon detector samples were not getting filled in root tree. Update?
• Helicity correlated difference by slug: DAQ and Analysis log 271
• Helicity correlated differences by slug with correct BSEN factor: DAQ and Analysis log 272

Laser

• Estimate of upper limit on "depolarization" of laser as it travels to IP (Paschke)
  • Note from last week: trivial. Kent needs to dig up his notes.

Photon Detector

• GEANT simulation updates
• "Analysis" updates (time dependence of slugs, etc.)
  • Time dependence of accumulator 0 by slug [1]

Electron Detector

• Systematic error from "floating CE" instead of floating Strip width.
  • Updated systematic error table: Edet log 487
  • Estimate of uncertainty on detector z-position: Edet log 491
  • For reference, some of Erik's original studies with fixed CE can be found here: Edet log 407
