Agenda

Usual meeting room (L210A).

Analyzer

• BPM sensitivities - we had the wrong values in analyzer (so did Qweak) Qweak beam log 274.
  • Since we don't look at these often in our analyzer, it is not urgent that we fix them - but it should be done soon.
  • I suggest looking at a couple runs to see how much difference it makes.

Laser

• Estimate of upper limit on "depolarization" of laser as it travels to IP (Paschke)

Photon Detector

• GEANT simulation updates
• "Analysis" updates (time dependence of slugs, etc.).

Electron Detector

• Systematic error from "floating CE" instead of floating Strip width.
• Initial pass2b results:
  • Edet log 472
  • Edet log 473
  • Edet log 474
