Description
QUOKKA is a versatile small angle neutron scattering (SANS) instrument in operation at the Australian research reactor, OPAL [1]. SANS is a powerful techniques for structural characterisation require a minimum of special preparation. As a conventional 40 m pinhole instrument operating with a neutron velocity selector the instrument1 is capable of providing a statistical and non-destructive perspective on structure over length scales from 10’s to 1000’s of Ångstrom. QUOKKA has a large flexible sample area, capable of accommodating a variety of sample environments including: standard 20 position sample changer for automated measurements on solids, liquids, pastes and powders; Couette geometry rheometer for in situ rheometry/SANS; a stopped flow device; and a differential scanning calorimeter. QUOKKA is available for general use through a biannual proposal system.
