Research facilities supported and routinely used by the
Mineral Physics Institute include the High Pressure Laboratory at Stony Brook
University, a High
Pressure facility at the National Synchrotron Light Source at Brookhaven National
Laboratory on Long Island, and contributions
to a similar facility at the Advanced Photon Source at Argonne National
Laboratory, near Chicago.
Acoustic measurements using ultrasonic interferometry are conducted at all
three of the above locations, as well as in benchtop
acoustic experiments in the Ultrasonics Laboratory at
Stony Brook University.
In addition to these facilities, MPI also makes use of the Microprobe and X-ray
Crystallography Laboratories in the Department of Geosciences at Stony Brook
University. Overviews of
each of these individual facilities can be found below, along with links to
their own respective pages for more information.
The X-Ray Diffraction Laboratory in the Department of
Geosciences at Stony
is one of the best-equipped laboratories in the country for mineralogical
crystallography. The open-access Integrated X-ray Scattering (InXS) user facility for powder and single crystal X-ray
diffraction (XRD) is often the starting point for initial characterization of
materials and in situ studies. Ongoing projects include research in low temperature
geochemistry, mineralogy, mineral physics, nano-science,
new materials and materials chemistry, environmental molecular science and
planetary research. At least 10 research groups regularly use InXS, either to provide publishable data, or as set-up for
work at national and international laboratories hosting X-ray synchrotron and
neuron facilities. Increasingly, users need to perform in situ work at variable
temperature (T) and to examine materials using a combination of wide angle and
small angle X-ray scattering (WAXS/SAXS).
The operation of this laboratory is overseen by Professor John Parise with the assistance of MPI Instructional Support
Specialist Kenneth Baldwin.
In 1985, the High Pressure Laboratory was established with
an Instrumentation and Facilities grant from the NSF Division of Earth Sciences
which supported the acquisition of three multi-anvil, large-volume,
high-pressure apparatuses. The first one (the Sumitomo) is designed for
synthesis experiments to 30 GPa and 3000 K. Another
was intended for in situ X-ray diffraction studies to 15 GPa
and 2000 K; this is the so-called SAM85 Press that is now located at Beamline X17B2 at the National Synchrotron Light Source.
The third multi-anvil apparatus is for ultrasonic measurements (the Kennedy
Press). These devices are distinguished by their large sample volumes and by
the ability to adjust and control the temperature and stress environment
surrounding the sample. The Sumitomo and Kennedy Presses are housed in a 2000
sq. ft. building renovated by the university and located just behind the Earth
and Space Sciences building, and are currently supported by Stony Brook
University through its support for MPI. This laboratory is under the Directorship
of Research Professor Baosheng Li.
The Mineral Physics Institute supports a laboratory for
making acoustic measurements on polycrystalline samples using ultrasonic
interferometry. We have a facility in the High Pressure Laboratory at Stony Brook
University for making
such measurements inside a Walker-type multi-anvil press at pressures up to 15 GPa. We support a similar, but smaller facility at the NSLS
which uses X-ray diffraction for simultaneous measurement of pressure using
diffraction standards. We also make use of another similar facility at the APS. In addition to high pressure experiments, we
have also developed techniques for conducting benchtop
acoustic experiments under ambient conditions. Using these facilities, we are
able to extend the pressure and temperature (P-T) over which this experimental
technique can be employed, as well as increase the accuracy of measurements
taken in these experiments. The Ultrasonics
Laboratory is overseen by Research Professor Baosheng
Li and Distinguished Service Professor Robert C. Liebermann.
The Mineral Physics Institute has been at the forefront of
developing techniques for using Synchrotron radiation in conducting in situ
high pressure and high temperature experiments. Currently, the research
conducted by members of MPI routinely makes use of Synchrotron facilities at
both the National Syncrotron Light Source at
Brookhaven Nation Lab in Upton,
NY, and the Advanced Photon
Source at Argonne National Laboratory in Argonne,
IL (outside of Chicago). Both of these facilities have beamlines with equipment specifically designed for
conducting a variety of high pressure/temperature experiments including both
large-volume multi-anvil apparatuses and small-volume Diamond Anvil Cells.
