Multianvil Apparatuses (2)
In August, 2001, we installed a 1000 ton Rockland Research press and a Walker-style octahedral multianvil. Efforts thus far have focused on the 12 mm truncation length octahedral cell (pictured below), which is calibrated to 10 GPa, and a COMPRES style 14-8 assembly for experiments at up to 15 GPa. There is also a cubic anvil module for large volume work to 6 GPa.
We log pressure, temperature, and a few other parameters during experiments in real time. For a peek into what is going on now in the multianvil, see our on-line data logger
The laboratory includes two Rockland Research end-loaded piston cylinder apparatuses pictured below. The "piston cylinder A" has a 250 ton end-load, while "piston cylinder B" has a 150 ton end load. Both are capable of pressures up to 3.5 GPa and temperatures up to 1800°C.
Acquisitions of the multianvil and piston cylinders were made possible by generous support from the National Science Foundation, NASA, the Department of Energy (to David Kohlstedt for the new hydraulic press), and from the University of Minnesota.
The Bruker Tensor 37 FTIR bench and Hyperion 2000 microscope pictured below is located in Shepherd Laboratories and is used principally by members of the Kohlstedt and Hirschmann research groups.
Acquisitions of the FTIR bench and microscope were made possible by generous support from the National Science Foundation and from the University of Minnesota.
The laboratory also features several Deltech furnaces with gas mixing capabilities.
Many of our analyses are done on the 5-channel JXA-8900 JEOL Superprobe, housed in the UMN Department of Earth Sciences.
We also take full advantage of the UMN Center for Interfacial Engineering Characterization Facility, located in the basement of Shepherd Labs. The characterization facility features a wide range of SEMs, TEMs, XRD.
