Nov. 2 - 4, 2018

Advanced Photon Source, Argonne National Laboratory

This two-and-half-day workshop is organized within the COMPRES infrastructure initiative to promote the application of the state-of-the-art Nuclear Resonant Scattering (NRS) techniques for characterizing the properties of materials under high P-T conditions of planetary interiors. The purpose of the workshop is to train current and potential scientific users in nuclear resonant inelastic x-ray scattering and data analysis using PHOENIX and SciPhon.

Nuclear Resonant Inelastic X-ray Scattering (NRIXS) provides information on vibrational and elastic properties, such as the phonon density of states, sound velocities, and isotope fractionation. NRIXS technique has become a powerful tool to understand the lattice and thermo-dynamics of Fe-bearing planetary materials in extreme pressure temperature conditions.

During the workshop we intend to

• provide an introduction to lattice dynamics
• provide an introduction of the NRIXS technique
• discuss NRIXS applications to important geophysical problems
• introduce PHOENIX and SciPhon for data evaluation
• offer hands-on training sessions for PHOENIX
• discuss experiment setup at the beamline and added features to the software
