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.
