Validation of Ion physics
  • Reaction level validation
    • Neutron production
    • (Projectile) Fragment production
    • Isotope production (Target, Projectile)
    • Pion production
    • Often done by developers
  • Integrated Validation
    • Thick Target Neutron Yield
    • Shape of Brag Peak
    • Rate of Singe Event Upset in Space
    • Often done by users

Validations of G4QMD (and BC)
  • Double Differential Neutron Production Cross Section
      • Target: Carbon to Lead
      • Projectile: C12 to Ar40
      • Projectile Energy: 290MeV/n to 600 MeV/n
  • Double Differential Neutron Yield
      • Target: Carbon to Lead
      • Projectile: C12 to Xe132
      • Projectile Energy: 290MeV/n to 800 MeV/n
  • Charge Changing Cross Section and Fragment Particle Productions
    • Comparing simulation results to 131 combinations of projectile and target particles
      • Target: Carbon to Lead
      • Projectile: C12 to Fe56
      • Projectile Energy: 290MeV/n to 10GeV/n
    • 98% of the results of charge changing cross sections are within 15% error
    • 84% of the results of charge changing cross sections are within 10% error

  • Thick Target Neutron Yield (TTNY);
  • EXFOR database (CYRIC facility experiment, Tohoku University, Japan);
  • „Physics list“ test;
  • Targets Li, Be, C, Al, Ta, W;
  • Energy 20-70 MeV, 100-400MeV/n;
  • Reactions (p,n), (d,n), (Ion,n);
    • Ion-Ion targets 100-400MeV/n*

* – very recent settings in the ESA project G4DNA, - this data are different from Tatsumi data reports (D.Satoh, T.Kurosawa, T.Sato, et.al. „Reevalution of secondary neutron spectra from thick targets ...“, Nucl. Instr. Meth. Phys. Res. Sect. A, v.582, 2-3, 507-515)

validation
Validation
  • Below 100MeV/n
    • Several validations
    • Lower limit of QMD ??
  • 100 MeV/n ~ 500 MeV/n
    • Many validation
  • 500 MeV/n ~ 5 GeV/n
    • Upper Limit of QMD, BC
    • A few validations
    • Data AGS,GSI, DUBNA, MSU
  • 5 GeV/n ~ 50 GeV/n
    • FTF
    • Limited number of validations
    • Data AGS,DUBNA,SPS
  • Beyond 50GeV/n
    • RHIC, LHC?

summary
Summary
  • Because of interest from the field of particle therapy, 100MeV/n to 500MeV/n are most validate by both developers and users
  • Below the 100MeV/n, data exist, but not well validated. Lower limit of QMD is not clear.
  • Beyond 5GeV/n, Validation against FTF predictions are required.
  • Compare to two previous presentations, I should admire that organization of this area need to be improve.
  • So I have a lot of hope for the next presentation.
  • Are developers making the validation result done by others reflect in future developments?
