Offspec is an advanced reflectometer giving access to nanometre length scales parallel and perpendicular to interfaces. It uses the technique of neutron spin-echo to encode the path that neutrons take through the instrument.

​​​​​​Reflectometer - Offspec ​

 

Science

Measurements of specular reflectivity give information about structure perpendicular to a surface interface, but an increasing number of important science and technology issues in the study of thin films, multilayers and interfaces concern structure in the plane of the interface.

Techniques

  • Reflectometry
  • Spin-Echo SANS
  • Spin-Echo Resolved Grazing Incidence Scattering (SERGIS)

Technical

Offspec can perform a variety of different measurements:

  1. Neutron Reflection (NR).
  2. Polarised neutron reflection with polarisation analysis (PNR)
  3. Spin-Echo Resolved Grazing Incidence Scattering (SERGIS)
  4. Spin-Echo Small Angle Neutron Scattering (SESANS)
  5. High angular resolution neutron reflection
  6. Neutron Reflection from macroscopically curved surfaces
  7. Quasi-Elastic Neutron Spin-Echo (Over a very limited dynamic range)
