X-ray emission spectroscopy with a laser-heated diamond anvil cell: a new experimental probe of the spin state of iron in the Earth's interior

Journal Article Lin, J -F ; Struzhkin, V V ; Jacobsen, S D ; ... - J. Synchrotron Rad.

Synchrotron-based X-ray emission spectroscopy (XES) is well suited to probing the local electronic structure of 3d transition metals such as Fe and Mn in their host phases. The laser-heated diamond anvil cell technique is uniquely capable of generating ultra-high static pressures and temperatures in excess of 100 GPa and 3000 K. Here X-ray emission spectroscopy and X-ray diffraction have been interfaced with the laser-heated diamond cell for studying the electronic spin states of iron in magnesiowuestite-(Mg{sub 0.75},Fe{sub 0.25})O and its crystal structure under lower-mantle conditions. X-ray emission spectra of the ferrous iron in a single crystal of magnesiowuestite-(Mg{sub 0.75},Fe{sub 0.25})Omore »« less
Powder diffraction from compressed molecular hydrogen in a diamond-anvil cell

Journal Article Besedin, S P ; Jephcoat, A P ; Hanfland, M ; ... - Applied Physics Letters

We report the first observation of x-ray powder-diffraction from molecular hydrogen in a diamond-anvil cell obtained at the European Synchrotron Radiation Facility using image-plate recording techniques. The sample was prepared by compression of hydrogen together with nickel powder in the high-pressure chamber. This result suggests that structural phase transitions in solid hydrogen could be studied directly with powder x-ray techniques. {copyright} {ital 1997 American Institute of Physics.}

First tests of THz transmission through a Diamond Anvil Cell

Conference Klopf, John

The THz source generated by the accelerator driver for the Jefferson Lab Free Electron Laser is unique in the world in its ability to deliver a high average power beam of ultrashort (<500 fs FWHM) broadband THz pulses. The spectrum of this source presents an ideal probe for many low energy phenomena, and the time structure enables measurement of dynamic processes with sub-ps resolution. An outline of the range of potential applications for this THz source as a probe of sub-ps dynamics in materials under extreme conditions will be presented. To demonstrate the capabilities of this source for just suchmore »« less

Properties of Vacancy Complexes with Hydrogen and Helium Atoms in Tungsten from First Principles

Journal Article Samolyuk, German D. ; Osetsky, Yury N. ; Stoller, Roger E. - Fusion Science and Technology

Tungsten and its alloys are the primary candidate materials for plasma-facing components in fusion reactors. The material is exposed to high-energy neutrons and the high flux of helium and hydrogen atoms. In this paper, we have studied the properties of vacancy clusters and their interaction with H and He in W using density functional theory. Convergence of calculations with respect to modeling cell size was investigated. It is demonstrated that vacancy cluster formation energy converges with small cells with a size of 6 × 6 × 6 (432 lattice sites) enough to consider a microvoid of up to six vacanciesmore »« less
