dc.description.sponsorshipTAIPAN is the thermal neutron spectrometer located at the reactor face of Australia’s OPAL reactor (ANSTO). TAIPAN hosts two interchangeable secondary instruments; the triple-axis spectrometer (TAS) and the Beryllium-filter spectrometer - which is a high-throughput, lowenergy, band-pass filter spectrometer. The TAS option has been operating in the user program since 2010 whilst the Be-filter is a newer addition, which began operating in 2015. TAIPAN is renowned for its versatility and high neutron flux which has allowed the TAS to successfully measure a broad range of samples including single crystals, powders, thin films, and co-aligned multi-crystal arrays [1,2]. While the TAS option is used mostly to study structural and magnetic excitations in materials, the Be-filter spectrometer is used to measure vibrational density of states from mainly powder samples [3]. TAIPAN has recently undergone some significant upgrades to improve the accessible momentum and energy range of both the TAS and the Be-filter spectrometers. Four key features have been modified to improve performance: a new sapphire filter translation stage mechanism has been installed to allow epithermal neutrons to pass to the monochromators; a new Cu-200 double-focussing monochromator has been installed to allow monochromatic scattering of neutrons up to 160 meV; a new tertiary shutter and snout have been designed to improve the signal to noise ratio and reduced background outside the instrument enclosure; and finally the accessible momentum transfer has been increased by re-designing the enclosure and expanding the available instrument range of motion. en_AU
