The main advantage of combining Brillouin spectroscopy (BS) with high-resolution x-ray diffraction (XRD) techniques is the ability to perform simultaneous measurements of velocities and elastic moduli (by Brillouin spectroscopy) and the volume/density (by XRD),
independent of any pressure standard. With this unique system, located
in the 13BM-D station (GSECARS, APS), it is now possible to study
materials with BS and XRD in situ at high pressure-temperature conditions that provide information essential for interpreting seismic observations and constraining models of the composition and evolution of the Earth. Although the system is designed to be very user-friendly, successful BS measurements at high pressure using diamond anvils requires special preparation and a thorough understanding of the peculiarities of the on-line high pressure BS technique. To help our users make the best use of this exceptional technique, we are organizing this COMPRES/GSECARS-supported workshop focusing on the major topics relevant to high pressure research using Brillouin spectroscopy combined with high-resolution x-ray diffraction techniques. The workshop will cover the following topics:
- fundamental aspects of Brillouin scattering
- experimental challenges of BS and XRD at high pressures and temperatures
- plenary lectures
- contributed presentations
- hands-on demonstrations
- software for data collection and analysis
- suggestions for future proposals
Limited financial support will be available for participants on first-come first-served basis, with priority given to domestic students, postdocs, and young scientists.
The final registration and abstract (one page maximum) deadline is May 31, 2009.
Argonne National Laboratory is a restricted-access site. ALL visitors who do not have an up-to-date APS badge must register with the APS. NON-U.S. CITIZENS must register AS SOON AS POSSIBLE; please see the "Notice to Non-U.S. Citizens" on the registration page.
