Agenda

Miscellaneous

• DAQ move next Monday --> EEL 126

1. DG has been documenting setup
2. Move VME crates and contents: NIM crates too?
3. Need to clean up in EEL a little
4. Meet in CH at 9:30 am, Monday if you want to help

• Collaboration meeting talk coordination

1. Compton overview (Dalton): to include transfer function, short edet and photon detector status, Monte Carlo studies, Pass 2 analysis preparations
2. Electron detector (Tvaskis): analysis improvements, studies, noise subtraction issues
3. Photon detector (Cornejo): Pass 1 slugwise results, linearity studies and first estimates

Laser

• Transfer function updates

Electron Detector

• GEANT 3 simulation, systematic test updates:

1. Effect of dead strips on measured asymmetry: Edet log 404
2. Simulating plane 4 w/half the strips not functioning Edet log 406
3. Extracted P accounting for detector tilt vs. not: Edet log 405
4. Various sensitivity tests (detector z, dipole field, detector tilt, beam energy): Edet log 407

• Effect of strip width vs. Compton edge: Edet log 408
  • Note: compare to Erik's MC study from last week: Edet log 402. Results seem pretty consistent.
  • Analysis issue: VT shows that if we can fit the Compton edge, our sensitivity to this goes away. Are we back to requiring a 3 parameter fit?

Photon Detector

• LED system update --> measurements with larger delta: any analysis of this data yet?
• Progress on Photon Detector Analysis Tasks
• Slug-wise analysis for Run 2 - any insight on shifts relative to Moller/edet?

Other analysis

• Radiative corrections: DAQ/Analysis log 259
