Multi-purpose instrument for SANS, diffraction and spectroscopy utilising the larmor precession of polarised neutrons. Larmor will provide a suite of techniques not currently possible at ISIS and will also expand the range of spatial and temporal length scales to new areas.

Science

Many of the soft matter themes relevant to science today will be extended to significantly longer length scales by SESANS, retaining good count rates and the advantages of neutron contrast variation. SESANS will allow detailed studies of long-range structure and inter-particle interactions in colloidal dispersions, foams, lamellar fragments, supramolecular conjugates, complex mixtures, composites, ‘templated’ and phase segregated systems.

Example applications

  • Soft matter and complex fluids
  • Food science
  • Bio-materials and pharmacy.

Techniques

  • SESANS (Spin-Echo Small Angle Neutron Scattering)
  • MIEZE (Modulated Intensity Experiment with Zero Effort)
  • MISANS (Hybrid instrument combining the MIEZE technique and conventional SANS)
  • Larmor diffraction
  •  NRSE (Neutron Resonant Spin-Echo Spectroscopy)

Did you know?

Larmor will be able to measure changes in materials ranging from 0.1 femtometers to 10 microns. Scaled up, that’s the same as measuring differences in size from 1 metre up to the distance from the Earth to the Sun.
