Petrology Lunch - In situ characterisation of (geo)materials under extreme conditions via synchrotron X-ray 4D µCT - Damien Freitas

We are pleased to announce a Petrology Lunch with Damien Freitas on the topic of: In situ characterisation of (geo)materials under extreme conditions via synchrotron X-ray 4D µCT.

Abstract:

Extreme conditions are common in engineering and earth sciences; however, they remain difficult and costly to access. While performing experiments at extreme conditions is now available in most laboratories, the in situ characterisation of the processes happening during the experiments, if allowed, relies mostly on indirect measurements (e.g acoustic waves monitoring, X-ray diffraction electrical conductivity, etc.).

Direct in situ characterisation methods developed around X-ray or neutron microtomography are now applicable to bespoke high pressure devices thanks for 3^rd and 4^Th generation of synchrotron light sources. At these facilities, the high-energy and flux beams can penetrate pressure vessels if they are made of light/intermediate materials. In this presentation, Damien will present the Norse arsenal: a new set of x-ray transparent triaxial deformation apparatus dedicated to time resolved (4D) synchrotron microtomography and their benefit for (geo)material sciences and engineering at crustal conditions.  The versatility of these rigs will be highlighted with example studies on fabric development during metamorphic reactions and high temperature fluid/rock interactions.
