dc.description.abstractEMU, the high-resolution neutron spectrometer installed at the OPAL reactor, ANSTO [1] delivers 1 μeV FWHM energy transfer resolution for an accessible ± 31 μeV energy transfer range. The spectral resolution is achieved by neutron backscattering from Si (111) on the primary and second flight paths, which also determines the accessible 0.35 to 1.95 Å^-1 momentum transfer range. Two years of user operation document strong demand for QENS characterization of microscopic diffusion processes in energy materials such as solid-state electrolytes, and increasingly in bio-related soft materials [2,3]. Over the same time frame most experiments were carried out with standard cryo-furnaces (2 to 800 K temperature range). Spectrometer beam-time access is merit-based, thus welcoming experiments beyond the first two-year ‘sample’, and including experiments that may require other ancillary equipment such as (existing) controlled-gas delivery, pressure, applied fields, Page 29 ANBUG-AINSE Neutron Scattering Symposium, AANSS 2018 / Book of Abstracts etc. Examples of the spectrometer capabilities will be shown, with an emphasis on QENS line shape and mean-square displacements analyses. Scientific support is presently focused on enabling data analysis of the collected data, and on the instrumental side reaching the design 0.1 Å^-1 minimum momentum transfer range and growing signal-to-noise ratio beyond its current ~ 1650:1 value. © The Authors.en_AU
