Important notice: NXSG4 has been superseeded by the more advanced NCrystal project.
While NXSG4 continues to work for now, it is no longer being actively developed.

Welcome to the NXSG4 website. NXSG4 is an extension to
Geant4 based on the
nxs library. In introduces effects of low-energy neutron scattering in polycrystalline materials, and is made freely available to the scientific community (see
license).
As an appetiser, here are a few plots from the
publication showing the effect of adding the correct crystal structure to aluminium:
Example: Improvement to neutron scattering cross section in aluminium when supplying the crystal structure via NXSG4.
Example: Patterns from Bragg diffraction on the crystal lattice planes for neutrons in aluminium when supplying the crystal structure via NXSG4.
