An advanced pulse neutron source and scientific challenges at J-PARC

Abstract

The newly commissioned 20 MW research reactor OPAL in Australia houses a number of instruments dedicated to crystallography as well instruments for neutron spectroscopy. The initial suite of instruments includes two powder diffractometers and a quasi-Laue single crystal instrument and was selected to reflect the strengths and interests of Australian Scientists. OPAL is characterised by extensive use of state-of-the-art neutron guides that deliver higher fluxes to the instruments. In this presentation I will firstly describe the technical capabilities of these instruments as well that of the closely the allied Small Angle Scattering instrument. Next I shall introduce the scientific capabilities of these instruments demonstrating how the high flux available at the instruments can be utilised either for highspeed or high resolution crystallography.
