Going Ultra: How We Can Increase the Length Scales Studied in Small-Angle Neutron Scattering

Abstract

Small-angle neutron scattering (SANS) has over the years proved to be a popular technique to investigate a variety of problems in materials science, since the length scales probed by this technique (1-100 nm) are ideal for many systems. However, there are a number of problems where the length scale of interest is larger. In order to study such systems it is possible to combine SANS with ultra-small-angle neutron scattering (USANS). This allows the study of structures from a few nanometers up to 50 µm. Here it is shown how the combination of SANS and USANS has allowed for a wider range of problems within materials science and polymer science to be solved.
