High-pressure instrumentation at CHESS
- Cornell High Energy Synchrotron Source, Wilson Lab, Cornell University, Ithaca New York 14853 (United States)
Diamond anvil cells have been used to generate a wide range of pressures, from 0.1 to over 400 GPa (for reference, the center of Earth is about 360 GPa). Samples are squeezed between two diamond anvils and studied using infrared, visible, and x-ray probes. Recently a bending magnet station at CHESS has become available for the general user for diamond anvil cell work using x rays. This has opened up new areas of research as the experimenters need only to bring a sample in a diamond anvil cell and can leave with the x-ray data mostly analyzed. Although most of the work has been with energy dispersive x-ray diffraction, some Laue work has been performed as well. Performing Laue diffraction studies with a station equipped for energy dispersive diffraction has the advantage that, with the addition of a rotation stage, the energy of a Laue diffracted spot can be analyzed.
