Agenda

Presentations:

Updates to mollersim geometry (Juliette)
- rotated the phi-defining collimator so that there is a closed section to beam left
- modified field determination code to be somewhat general - can rotate the field easily now
- coded the upstream torus in GDML (see elog 202)
  - plan to also hard-code to maintain the ability to continue to use it - but I REALLY like the GDML
  - will compare the results for hard-coded vs. GDML defined
  - the GDML write from GEANT4 did NOT create tesselated volumes, but the parameterization is lost
  - if we code directly in GDML it is really easy to parameterize things AND to modularize things (see elog 205)
Changing code to write volume numbers of sensitive volumes to root file - need a better way of identifying them?
- 0-999 for actual detectors (possibly 0-99 for plane detectors and 100-999 for pieces quartz?, tracking?)
- 1000-1999 for collimators
- 2000-???? for coils
Incidentally, no luck with GEANT4 with GDML on windows - Mauri is working on a Fedora 15 package and I now have a Fedora 15 virtual machine

Collimator/field configuration comparison update (Sereres)
- Plots of asymmetries
- Plots of ee/ep separation and peak widths
