Generic Processes & Materials - Workplan 2018

Version 2.0

 

• Geometry Biasing with Importance:
• Comparison between generic and importance biasing
• Investigation B03 rare crashes
• Investigate extension of design to support for multiple particle types
• Differential Cross-section class:
• Design and implementation of at least an elastic diff. cross-section class to be used in DXTRAN option
• Make use of this class in some processes
• Discuss access of this cross-section class : eg adding method(s) to G4VProcess
• Generic Biasing:
• Continue enriching event biasing options:
  • Leading particle (alternative to existing one in HAD)
  • DXTRAN-like biasing
  • Implicit capture
    • Clarify MCNP scheme for implicit capture
• Extend generic biasing scheme for at rest case
• Statistical test suite to verify correctness of biasing wrt to analog
• Feasibility studies and prototyping
  • Biasing of charged particles, with cross-section changing over the step
  • Use of occurence biasing to allow continuous density change inside a same volume
  • Material/isotope biasing
  • Woodcock tracking
• Discuss interest of sharing same limiters (scoring, biasing, fast. sim., etc.) for parallel geometries
• Fast Simulation:
• Improve usability enriching physics list constructor of fast simulation
• Revision and C++11 adoption for GFlash models
• Materials:
• Redesign of G4MaterialPropertyTable
  • Provide better interface 
  • Run-time performance
  • Thread safety
• Support for materials category
• Radiotherapy & radioprotection:
• Work items imported from user’s requirements 4302 - 4305
• Tallying of the ambient dose equivalent H*(10) (value + error or tally)
• Dose H*(10) resulting from radioactive decay at different time windows
• Computation of activation in bunker therapy by protons, neutrons, and gammas
• Definition of irradiation profile for radiation therapy.
