Evaluations of pressure-transmitting media for cryogenic experiments with diamond anvil cell.
The fourteen kinds of pressure-transmitting media were evaluated by the ruby fluorescence method at room temperature, 77 K using the diamond anvil cell (DAC) up to 10 GPa in order to find appropriate media for use in low temperature physics. The investigated media are a 1:1 mixture by volume of Fluorinert FC-70 and FC-77, Daphne 7373 and 7474, NaCl, silicon oil (polydimethylsiloxane), Vaseline,...
متن کاملDevelopment of a low-pressure diamond anvil cell and analytical tools to monitor microbial activities in situ under controlled P and T.
We have designed a new low-pressure Diamond Anvil Cell (DAC), calibrated two novel pressure calibrants and validated the use of semi-quantitative Raman and X-ray spectroscopies to monitor the fate of microbes, their metabolism or their cellular components under controlled pressures and temperatures in the 0.1-1.4 GPa and 20-300 degrees C P,T range. The low-pressure DAC has a 250- to 600-microm-...
متن کاملA compact bellows-driven diamond anvil cell for high-pressure, low-temperature magnetic measurements.
We present the design of an efficient bellows-controlled diamond anvil cell that is optimized for use inside the bores of high-field superconducting magnets in helium-3 cryostats, dilution refrigerators, and commercial physical property measurement systems. Design of this non-magnetic pressure cell focuses on in situ pressure tuning and measurement by means of a helium-filled bellows actuator a...
متن کاملInvited article: High-pressure techniques for condensed matter physics at low temperature.
Condensed matter experiments at high pressure accentuate the need for accurate pressure scales over a broad range of temperatures, as well as placing a premium on a homogeneous pressure environment. However, challenges remain in diamond anvil cell technology, including both the quality of various pressure transmitting media and the accuracy of secondary pressure scales at low temperature. We di...
متن کاملHigh Brilliance and High Pressure: A New Diamond Anvil Cell Facility at the Advanced Photon Source
High energy and high brilliance make the Advanced Photon Source (APS) an ideal tool for high pressure studies. In this paper, we describe the diamond anvil cell (DAC) facility that is being developed for the APS by the GeoSoilEnviroCARS group of the Consortium for Advanced Radiation Sources (CARS). The DAC program aims at studying properties of materials across the entire pressure-temperature s...
