Can neutron tomography detect in-situ density changes?

Vili Grigorova

Neutron tomography is a powerful non-destructive technique used to study the internal structure of objects. As opposed to the X-ray tomography, neutron tomography can penetrate objects made of an element with high atomic numbers. High-pressure apparatus such as the Paris-Edinburgh press are used routinely up to10 GPa and 1500 °C. Adapting such apparatus to be used in a neutron tomography beam will allow us to obtain in-situ 2D and 3D images of samples while held at high pressures and temperatures to induce density changes. My work included (1) a selection of neutron friendly materials for the frame structure of the press and the sample assembly, (2) pressure and temperature calibration of the new sample assembly cell, and (3) image quality analysis of the DINGO beamline.

About the GSA

The Geological Society of Australia was established as a non-profit organisation in 1952 to promote, advance and support Earth sciences in Australia.

As a broadly based professional society that aims to represent all Earth Science disciplines, the GSA attracts a wide diversity of members working in a similarly broad range of industries.
