Validation of neutrons in Geant4 using TARC data: production, interaction and transportation

The TARC (Transumatation by Adiabatic Resonance Crossing) experiment has been simulated with the Geant4 toolkit. The experiment measured neutron production from 2.5 GeV/c and 3.5 GeV/c protons incident on high purity lead. The Geant4 simulation utilised either the Bertini or Binary nuclear cascade m...

Descripción
Sumario:The TARC (Transumatation by Adiabatic Resonance Crossing) experiment has been simulated with the Geant4 toolkit. The experiment measured neutron production from 2.5 GeV/c and 3.5 GeV/c protons incident on high purity lead. The Geant4 simulation utilised either the Bertini or Binary nuclear cascade models together with the low energy Neutron_HP extension. The neutron time-energy correlation, absolute fluence spectrum, and radial fluences are compared between data and simulation. Recent improvements to the PreCompound and De-excitation modules within Geant4 are presented and their influence on the TARC simulation demonstrated. Overall the Geant4 simulation reproduces the TARC data.
