Abstract
A small-angle neutron scattering (SANS) instrument[1] is being designed as part of the initial instrument suite for the new 20-MW Australian Reactor, OPAL. This instrument is designed to study structure on 1-100nm length scales on the wide variety of materials of scientific and technological importance for which neutron scattering has some considerable advantages over its x-ray counterpart, in particular (i) systems for which isotopic (H/D) contrast may be employed to highlight ordering, such as self-assembled polymer, surfactant and bio-molecule mesophases, and (ii) systems which scatter the neutron due to its magnetic moment, such as flux line penetration arrays in type II superconductors. The OPAL SANS instrument, receiving neutrons from a large liquid-D2 cold source, will be in the spirit of the world’s best facilities and will greatly build upon the Australian Nuclear Science and Technology Organisation’s existing expertise and facilities. Scheduled to begin operation in 2007, it will provide Australian and international researchers with opportunities to access state-of-the-art SANS instrumentation. [1] E.P. Gilbert, J.C.
