General Information

Instrument:

Spin-echo small-angle neutron scattering SESANS

Location:

Experimental neutron hall, Reactor Institute Delft, Mekelweg 15, Delft (building #50)

Key words:

small-angle neutron scattering

Main application:

measurement structures on length scales from 10 nm 10 μm. It is a scattering technique that directly yields the density correlation function in real space. It works best on strongly scattering materials, that are usually concentrated materials with structural features on a micron length scale. Applications up till now are on colloids, protein clusters, micro emulsions (food material for example), granular materials, polymer fibres, lithographic gratings and voids and precipitates in metals.
