Small Angle Neutron Scattering (SANS) is a technique that allows characterizing structures or objects on the nanometer scale, typically in the range between 1 nm and 150 nm. The information one can extract from SANS is primarily the average size, size distribution and spatial correlation
The Quokka small-angle neutron-scattering instrument is the largest (40-m long after the guide bunker) in the guide hall. The small-angle neutron-scattering technique was a major driver for getting the high-performance cold source into OPAL.
For example, the toughness of high impact plastics depends on the admixture of stiff and flexible segments of polymer molecules Small-angle X-ray scattering (SAXS)/small-angle neutron scattering (SANS) are fundamental tools applied for analyzing the microstructural characterization of colloidal particles (Gradzielski, 2008). In the SAXS experiment, the typical SAXS pattern, which is a function between intensity and scattering vector, is obtained at low angles (typically 0.1–10°). Small-angle neutron scattering (SANS) involves the study of diffraction in the regime where the magnitude of the momentum transfer, Q, is small compared with the position of the first peak in the structure factor or the highest d-spacing Bragg peak. 3 Small Angle Neutron Scattering The discussion above focussed on atomic properties, but there are many problems where the length scales in question are much larger than atomic dimensions and it is easier to think in terms of material properties. In order to do this we de ne a quantity called the scattering length density ˆ(r) = b i (r r i) (16) or ˆ= P n i b Small Angle Neutron Scattering (SANS) explores the mesostructures of liquids and solids on length scales ranging from 1 nanometre to about a micron. There are 3 dedicated SANS instruments and a fourth instrument can also be used for SANS.
