Agenda

Laser

  • Laser repair today!
  • Shorts ok for laser work! Needs to be put in Atlis.

Photon Detector

Electron Detector

  • GEANT 3 simulation updates:
  1. MC uncertainty calculation comparisons: Edet log 388
  2. Effect of 2 vs. 3 parameter fit in the limit of very high precision: Edet log 389
  3. Chi-squared for fit to "tilted" detector: Edet log 390

Pass 2 analysis preparation

  • What is completed ?
  1. BCM Calibration
  2. EPICS in Slow_Tree
  • What needs to be checked/completed (Complete list)
  1. BPM Calibration
  2. Database ( list of laser-cycle variables to be extracted from the Pass-2 analysis )
  3. Macros
    1. Accum0,1,3
    2. Beamline
    3. eDet analysis...
    4. the photon-detector and electron-detector using same cut files on Laser and Beam
  • Goal: Start replay July 6-9

Miscellaneous

  1. Juan Carlos (photon detector)
  2. Amrendra (electron detector)
  3.  ??????? (polarimetry overview) --> see comment from Roger's email:
"Electron Beam Polarimetry at the sub-1% level": This could be a 
contributed talk that generally discusses the Qweak approach to 
polarimetry (Moller + Compton), the goals, and anticipated results after 
further analysis.  The emphasis would be on the coordinated approach, 
the general performance of the systems, and the effort to 
cross-calibrate (even though final results may not be available on that 
yet).
