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 ≃ 1.0 × 10−3 Å−1 to ∼1.8 Å−1) and variable wavelength resolution (Δλ/λ ≃ 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. A description is presented of the instrument design and performance of BILBY, the new time‐of‐flight small‐angle neutron scattering instrument located at the Australian Nuclear Science and Technology Organisation.

Presents patterns of small-angle X-ray scattering from two polyolefin samples that exhibit three-dimensional (3-d) symmetry. Materials whose morphology is of low symmetry resulting from processes for forming products from synthetic polymers; Mapping of the full 3-d scattering pattern as required for characterizing such morphology using small-angle scattering.

Examines the specificity of microstructures using temperature-induced contrast variation technique. Pattern of scattering; Mechanisms of liquid-like scattering from amorphous components; Characterization of glass transition effects in semicrystalline polymers.
