We use small angle neutron scattering (SANS) to characterize the microstructure of materials both at rest and under flow or other deformations. As neutron flux is significantly lower than x-ray flux, we develop and implement advanced data analysis techniques to maximize the temporal resolution of SANS experiments. We also design new SANS fitting algorithms and sample environments for probing structures under various deformations, including flow or magnetic fields.

Typical SANS patterns are a convolution of the time-dependent microstructure and time-bin. Implementing sliding bins improves temporal resolution; deconvolution procedures improve temporal precision.
