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
