Description
Taipan, the highest flux thermal neutron scattering instrument at ACNS, was originally built as a traditional triple-axis spectrometer. In 2016 a beryllium filter analyser spectrometer was added for increased versatility. The Be-filter acts like a low-energy band-pass filter ideal for investigating lattice dynamics and molecular vibrations over a wide energy range. It is particularly well suited to measuring the motion within materials containing light elements such as hydrogen.
We have successfully created a robust method of treating data from the Taipan filter-analyser and present the method within this poster [1]. The data-treatment process includes correction for the non-linear energy variation of a particular monochromator, removal of higher-order wavelength contamination, and estimation of low-energy multiple-scattering. The steps described here can be utilized by all users of the Australian Nuclear Science and Technology Organisation “Be-filter”—past, present, and future.
