| Abstract |
We characterise the neutron flux and energy spectra produced by protons on a lead target. This may enable studies of the neutronics of an ADSR, to be separated from the higher energy spallation processes, in order to explore te potential of ADSR as a better alternative for energy production, safety and waste transmutation. We consider a range of proton energies, and show how the numbers of neutrons produced can be fitted by some simple functions of the proton energy, as can the spatial and energy distributions. These calculations were performed in both MCNPX and Geant4 and we compare and benchmark the low energy neutron spectra obtained by MCNPX code and a Monte Carlo Code Geant4 against each other. Discrepancies were found for the low energy neutron spectrum, but by using different models as calculation options for low energy neutrons in Geant4, this disagreement has been significantly reduced.
