TL;DR
This paper compares neutron propagation simulations in rock for underground experiments using GEANT4, MCNPX, and GEANT3, showing good agreement in low-energy neutron transport across different materials.
Contribution
It provides a comparative analysis of neutron transport simulations in different Monte Carlo codes for underground physics experiments.
Findings
Good agreement between GEANT4, MCNPX, and GEANT3 in low-energy neutron transport.
Neutron propagation results are consistent across lead and hydrocarbon materials.
Simulations help validate modeling approaches for underground neutron backgrounds.
Abstract
Simulations of neutron background from rock for underground experiments are presented. Neutron propagation through two types of rock, lead and hydrocarbon material is discussed. The results show a reasonably good agreement between GEANT4, MCNPX and GEANT3 in transporting low-energy neutrons.
