Agenda

Usual meeting room (L210A).

Miscellaneous

• Dave G. out of town next week - anyone want to run the meeting?
• Ideas for laser work that we can sub-contract? FEL is looking for work.

Analyzer

• BPM sensitivities - we had the wrong values in analyzer (so did Qweak) Qweak beam log 274.
  • Still need to look at a couple examples to examine impact.
• Scripts - any progress on the photon detector samples?

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.
  • Magnetic field variation: Edet log 477
  • Detector Z position variation: Edet log 478
  • For reference, some of Erik's original studies with fixed CE can be found here: Edet log 407
• Systematic examination of distribution of residuals for a given strip
