CERN Accelerating science


Version 1.0

  • Geometry Biasing with Importance:
    • Investigate the differences between Generic Biasing importance biasing and the existing intrinsic geometrical biasing.
    • Debug the geometrical biasing for the case of deleted and reinstantiated geometries.
    • Investigate the "switchability" between generic and geometrical biasing
    • Clean up and revise test33 to correctly test biasing in MT mode
    • Command line and "smart" biasing scheme

  • Reverse Monte Carlo:
    • Improvments of EM ReverseMC for case of thick shielding (1/2)
    • Continue/Finish Migration of ReverseMC to MT (2/2)

  • Generic process:
    • Consider interest of new method G4VProcess::StartEvent()

  • Generic Biasing:
    • Continue enriching event biasing options (1/2 - 2/2):
      • Brem. splitting (alternative to existing one in EM); refactor existing example to source
      • Leading particle (alternative to existing one in HAD)
    • Statistical test suite to verify correctness of biasing wrt to analog (1/2)
    • Improvements:
      • Use of generic track extension to consolidate bookeeping (1/2)
      • Allow/demonstrate use of parallel worlds (2/2)
    • Feasibility studies and prototyping (2/2)
      • Biasing of charged particles, with cross-section changing over the step
      • Use of occurence biasing to allow continuous density change inside a same volume
      • DXTRAN-like biasing
      • Material/isotope biasing
      • Woodcock tracking

  • Materials:
    • Verify and improve handling of gases (bug report 1704 indicate a problem)
    • Prospective: coping with molecular aspects for low energy ? (1/2 - 2/2)
