Neutron scattering methods for soft condensed matter and food materials

Spin-echo small-angle neutron scattering (SESANS)

SESANS is a new efficient method to measure structures of materials in real space. Structures can be determined over three orders of magnitude in length scale, from 20 nanometer to 20 micrometer, which is an order of magnitude larger than conventional small-angle neutron scattering (SANS). In contrast to traditional scattering methods, the data in real space, rather than reciprocal space, this makes interpretation easier. These properties make SESANS a new powerful tool for the study of structural properties of materials.

In Delft we have built the first dedicated SESANS-instrument. The project has been continued with the development of the spin-echo components of OFFSPEC the reflectometer and Larmor the multi-purpose instrument for SANS at the 2nd target station at ISIS.

In the pages below you can read several explanations about the SESANS and examples of applications.
