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)
