LAD - Liquids and Amorphous Diffractometer

Click here for information about the LAD celebration meeting

LAD ceased operation on 17^th December 1998.

LAD was a total diffraction instrument optimised for the study of amorphous solids and liquids.

LAD Publications

LAD can be used for...

• Structural studies of glasses (including oxide glasses, chalcogenide glasses, metallic glasses)

• Structural studies of liquids (including molten salts, liquid metals and alloys, molecular fluids) and gases

• Studies of anisotropy in planar samples.

• Studies of disorder in crystalline materials

• High resolution powder diffraction.

Dr. Simon Hibble, Dr Martin Dove (see section on cristobalite on neutron scattering page), Dr Adrian Barnes, Narcis Clavaguera, Adrian Barnes, Phil Salmon, Jan Swenson, Ulf Dahlborg

A comprehensive data analysis suite (the 'ATLAS' suite) is available to reduce the data and apply full corrections so as to yield a final single S(Q) structure factor curve.
