In situ laser heating and radial synchrotron X-ray diffraction in a diamond anvil cell (2007)

Kunz, Martin, Caldwell, Wendel A., Miyagi, Lowell, Wenk, Hans-Rudolf

We report a first combination of diamond anvil cell radial x-ray diffraction with in situ laser heating. The laser-heating setup of ALS beamline 12.2.2 was modified to allow one-sided heating of a...

A Beamline for High-Pressure Studies at the Advanced Light Source with a Superconducting Bending Magnet as the Source (2005)

Kunz, Martin, MacDowell, Alastair A., Caldwell, Wendel A., Cambie, Daniella, Celestre, Richard S., Domning, Edward E., ...

A new facility for high-pressure diffraction and spectroscopy using diamond anvil high-pressure cells has been built at the Advanced Light Source on Beamline 12.2.2. This beamline benefits from the...

Crystal structure and thermoelastic properties of (Mg0.91Fe0.09)SiO3 postperovskite up to 135 GPa and 2,700 K

Shim, Sang-Heon, Catalli, Krystle, Hustoft, Justin, Kubo, Atsushi, Prakapenka, Vitali B., Caldwell, Wendel A., ...

Intriguing seismic observations have been made for the bottom 400 km of Earth's mantle (the D″ region) over the past few decades, yet the origin of these seismic structures has not been well...
