D7 - Diffuse Scattering Spectrometer

A closer look

This view provide more details on the core of the instrument

A look inside D7

The shielding of the instrument can part in two thus revealing its components.

A general view of the instrument

D7 is a cold neutron multidetector diffractometer with full XYZ polarisation analysis. This allows the unambiguous separation of nuclear, magnetic and nuclear-spin-incoherent scattering contributions simultaneously over a large range of scattering vector Q, and is therefore ideal in the study of diffuse scattering from disordered magnetic materials.

It is also a time-focusing time-of-flight spectrometer with polarisation analysis.

D7 - Diffuse Scattering Spectrometer

D7 has been dismantled. The new permanently-polarized diffuse scattering spectrometer D007 delivered its first neutrons in 2024. Further developments have been realised and first users have been welcomed in 2025.

The diffuse scattering spectrometer D7 is a general purpose neutron polarisation analysis spectrometer, designed to study nuclear and magnetic short range ordered materials and magnetic defect structures.

Applications

  • Magnetic short range order in frustrated magnets and spin-glasses
  • Studies of non-collinear ferromagnetism
  • Extended magnetic defects in antiferromagnetic materials
  • Studies of hydrogen motion
  • Separation of collective and single particle excitations
