Performance and characteristics of the BILBY time-of-flight small-angle neutron scattering instrument

BILBY is a recently constructed and commissioned time-of-flight small-angle neutron scattering instrument, operated by the Australian Centre for Neutron Scattering at the Australian Nuclear Science and Technology Organisation (ANSTO). BILBY provides a wide accessible q range (q similar or equal to 1.0 x 10(-3)angstrom(-1) to approximate to 1.8 angstrom(-1)) and variable wavelength resolution (/ similar or equal to 3-30%) to complement the other small-angle and ultra-small-angle neutron scattering capabilities available at ANSTO. Since its construction, BILBY has been used to study samples from a wide range of scientific disciplines, including biology, chemistry, physics and materials science. This article describes the BILBY design and components, and shows data collected from a number of reference samples.
