Abstract
Quokka is a 40 metre small angle neutron scattering instrument installed on the cold source of the OPAL research reactor operated by ANSTO. The instrument is designed to enable measurements of scattering vectors over three orders of magnitude, from 3 x 10-4 Å-1< q < 0.7 Å-1. The instrument is able to perform polarized neutron experiments and a new high count rate detector will be commissioned on the instrument next year. In addition to the standard 20-position automatic sample changer, a wide range of sample environment equipment is available for use on the beamline, some of which are unique worldwide. A rheometer, rapid heat/quench cell, dynamic light scattering, differential scanning calorimetry and a stop-flow mixing cell are all in use. The capabilities and performance of Quokka will be presented.
