GSECARS
A national user facility for frontier research in the earth sciences using synchrotron radiation at the Advanced Photon Source, Argonne National Laboratory.
GSECARS provides earth scientists with access to the high-brilliance hard x-rays from this third-generation synchrotron light source. All principal synchrotron-based analytical techniques in demand by earth scientists are being brought to bear on earth science problems:
-
High-pressure/high-temperature crystallography and spectroscopy using the diamond anvil cell
-
High-pressure/high-temperature crystallography and imaging using the large-volume press
-
Powder, single crystal and interface diffraction
-
Inelastic x-ray scattering
-
X-ray absorption fine structure spectroscopy
-
X-ray fluorescence microprobe analysis
-
Microtomography
Future of COMPRES, GSECARS, and Synchrotron-Based Earth Science Research
Recently, NSF released a proposal solicitation for a new organization for management of synchrotron-based analytical capabilities for Earth and Environmental Sciences research and training. GSECARS is working with the larger Geoscience community to create a new and innovative organization in response to this call. More information about this effort can be found here.

Scientists find strange black ‘superionic ice’ that could exist inside other planets
Scientists used diamonds and a beam of brilliant X-rays to recreate the conditions deep inside planets, and found a new phase of water called “superionic ice.”

‘Weird, hot, black ice’: Scientists discover new phase of water
It’s called superionic ice, and until recently it had only been glimpsed for a fleeting moment. In a study published in the journal Nature Physics, researchers managed to create the substance using the same high temperatures and pressures that can be found inside ice giants Uranus and Neptune.
