Role at ANSTO
Hal leads the Institute's Helium-3 Polarisation Project. The project will bring polarised Helium-3 based neutron polarisers and analysers to several new instruments, including PELICAN, PLATYPUS, QUOKKA, WOMBAT, SIKA and TAIPAN. His research interests are in the areas of polarised Helium-3 application in neutron scattering works, magnetic thin film physics, magnetic structures and magnetic excitations in materials, and high-resolution measurement techniques in biology and chemistry.
His technical expertise includes polarised Helium-3 production and the application to neutron scattering work, polarised neutron scattering (reflectometry, inelastic scattering, diffraction), instrumentation (spin-echo resolved grazing-incident scattering, reflectometer, neutron optics and guides, self-shielded asymmetric high-field superconducting magnets, Monte-Carlo simulation of neutron scattering instruments), neutron interferometry, and UHV thin-film deposition and characterisation techniques.
