Achieving a good signal-to-background ratio in neutron scattering experiments is a crucial factor in instrument and sample environment design. However, in current Monte Carlo simulation software, not all neutron interactions are considered. If all the neutron interactions that contribute to the background can be included, the expected signal-to-background ratios can be simulated and used to design better instruments.
All neutron interactions contribute to the background, both inside and around the sample. Cryomagnets and pressure cells, for example, produce undesired scattering. Modelling them completely also means taking into account the inelastic scattering contribution and the material microstructure too.

Dr. Victor Laliena from ICMA located in Zaragoza, Spain, has developed a code for calculating the interactions which depend on the microstructure...
