Upgrade of the Multi-Anvil High-Pressure Facility at Arizona State University

Project: Research project

Description

Intellectual merit of the proposed activity: We are seeking to upgrade the multi-anvil facility at Arizona State University (ASU) by adding a second 1000-ton multi-anvil high pressure device. The facility, located in the Chemistry Department, currently houses a single 1000-ton multi-anvil and two 300-ton multi-anvils. The 1000-ton multi-anvil has been fully booked for the last 4 years with between 90 and 100 runs per year that are all at forces over 300 tons. Given the duration of each run, this has meant that the press has been in use nearly all the time. The demand on this press is increasing because of an increasing number of users, combined with the ease of use that has resulted from the COMPRES Multi-Anvil Cell Assembly Development project which is also located at ASU. Like other laboratories, we are buying these cells from the COMPRES project for use in our own laboratory, and the cells have made new capabilities available and diminished the preparation time considerably. Whereas 4 years ago the preparation of the experiments was the primary limit on the output of the lab, now the press time is the main limit. We have some of the materials on hand for a second 1000 ton multi-anvil, in particular a Walker module and a power supply, but are seeking a press and a pumping system, which are essential components for us to build the second multi-anvil. We project, based on the existing funded programs that rely on the press, that our single 1000-ton press will be over-committed by greater than a factor of two for the foreseeable future, which we feel justifies the purchase of a second press. The multi-anvil laboratory is an open facility that is used for experiments in mineral kinetics, phase equilibria, high pressure crystal growth, and phase synthesis. It is run in tandem with a gas vessel/piston cylinder lab (Depths of the Earth Lab) and a diamond-anvil cell (DAC) laboratory, which together allow a broad spectrum of high-pressure experiments and research. The throughput of the multi-anvil lab is expected to double with the building of the second multi-anvil. Broader impacts resulting from the proposed activity: The multi-anvil laboratory, in combination with the other high-pressure facilities at ASU, constitutes a large interdisciplinary effort in high-pressure science. We are collaborating in an interdisciplinary fashion with Chemists, whose high-pressure experiments are often inspired by mineralogical findings and who have developed an interest in the equipment originally developed for Earth Science, and with Physicists, who have developed their own high pressure technology focused on low temperatures, but need access to the unique high pressure samples that can be created in a multianvil. The second press combined with current improvements in the DAC and the Depths of the Earth laboratory will allow us to make a stronger imprint on all these communities. We support the broader earth-science community through the COMPRES Multi-anvil Cell Assembly Development Project, for which one of the PIs (KL) develops and supplies cell assemblies for high-pressure laboratories throughout the United States. Our laboratory also trains graduate and undergraduate students in earth sciences, chemistry and physics in high-pressure research. We further support undergraduate education through educational modules, such as diamond-making laboratory exercise in the Mineralogy course at ASU. Acquisition of a new 1000-ton multi-anvil press at ASU will allow us to expand our training activities for undergraduate students, graduate students, and post-docs, which will help build the pool of young scientists interested in doing high-pressure research.
