24. Brillouin Scattering at High Pressures and Temperatures: Potential Applications at a 3rd Generation Synchrotron Source such as PETRA III

Brillouin spectroscopy is a technique that allows us to measure the shear elastic properties of solids at very high pressures and temperatures relevant for interpreting seismic heterogeneity in the deep Earth. In particular, Brillouin spectroscopy is one of the very few methods that can allow us to determine the full single-crystal elastic tensor of solids up to extreme conditions, with...

In the last few years, a new experimental technique was designed to study the plastic properties of materials under high pressure in the diamond anvil cell. In those experiments, a polycrystalline sample is deformed between the two diamond anvils. Stress and lattice preferred orientations are then studied using diffraction in a radial geometry (i.e. with the incoming x-ray beam perpendicular...
