Quokka will be one of the best small-angle neutron scattering (SANS) instruments in the world. SANS is a highly versatile technique for investigating a wide range of materials including polymers, emulsions, colloids, superconductors, porous materials, geological samples, alloys, ceramics and biological molecules such as proteins and membranes.

Kowari is a residual stress diffractometer which can be used for ‘strain scanning’ of large engineering components as large as 1000 kilograms. The integrity of engineering components often depends on strains and stresses inside the material. For example, rails can fail if stresses exceed the ‘ultimate tensile stress’.
