Abstract Scope |
X-ray Photon Correlation Spectroscopy (XPCS) is a spatio-temporal coherent X-ray scattering technique that probes slow collective dynamics at the nanometric and atomic scale based on the observation of fluctuating far-field speckle patterns.
This technique has been successfully applied to the investigation of slow relaxation processes occurring in metallic glass-formers undergoing dynamical arrest, polyamorphism and aging, such as liquid alloys and metallic glasses.
The Extreme Brilliance Source (EBS) upgrade of synchrotron ESRF has extended dramatically the dynamical range of XPCS with a considerable increase of the coherent flux at higher photon energies, making possible in-situ high pressure (HP) studies in complex systems.
In this talk, I will present recent experimental results on the atomic motion in a metallic glass obtained with HP-XPCS at ESRF-EBS, and I will also illustrate some of the future scientific possibilities offered by this technique in the field of high pressure science in glass formers. |
