Simulation of neutron dark-field data for grating-based interferometers.

ABSTRACT: Hierarchical structures and heterogeneous materials are found in many natural and engineered systems including additive manufacturing, alternative energy, biology and polymer science. Though the structure-function relationship is important for developing more advanced materials, structural characterization over broad length scales often requires multiple complementary measurements. Neutron far-field interferometry aims to enable multi-scale characterization by combining the best of neutron imaging with small-angle neutron scattering (SANS) via dark-field imaging. The microstructure, nominally from 1 nm to 10 μm, is averaged over each volume element ~(50 μm)³ in the sample, resulting in a 'tomographic SANS' measurement. Unlike in small-angle scattering, there are few analytical m
