Large dynamic range small-angle diffractometer

A general view of the instrument

This 3D layout shows how the main parts of the instrument are organised.

D22 is the small-angle neutron scattering facility with the highest flux at the sample in a wavelength range of 4.5 to 40 Å.

This is due to:

  • the brilliant horizontal cold source
  • the short rotor (25 cm) and high transmission of its velocity selector
  • the relatively large beam cross-section of 55 x 40 mm of the guide H512.
