Study in 'Science' finds missing piece of biogeochemical puzzle in aquifers using 13-ID-E's sulfur spectroscopy capabilties. Details in Argonne's press release

New paper in Science showcases the new sulfur capabilities at 13 IDE

High pressure x-ray tomographic microscopy module

The HPXTM module helps researchers study the texture change of their sample under extreme pressure and temperature conditions by collecting in-situ HP/HT 3D x-ray tomographic images.

XRF microtomography reconstructions of arabidopsis seed

High-resolution XRF microtomography of Arabidopsis seed. Reconstructed distribution of Fe, Mn, Zn and Ca, K, Zn are shown, images in fly-scan mode with a pixel resolution of 1 µm (13IDE,T. Punshon, Dartmouth).

High-speed and high-resolution X-ray fluorescence microtomography

GSECARS is 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        

Deadline for 2014-3 General User Proposals
(Oct 1 - Dec 16, 2014)was Friday, July 11th at
11:59pm CST.   You can still apply with a
Rapid Access Proposal.     

New research may explain how the oceans were created at the beginning of the Earth's formation.


Northwestern University geophysicist Steve Jacobsen and University of New Mexico seismologist Brandon Schmandt with a team of researchers have  found evidence of a long-term H2O trap in the transition zone.  Click for details.

Figure above : Laboratory experiments on hydrous ringwoodite. (A) Single-crystal of hydrous ringwoodite (blue crystal) containing 1 wt% H2O inside a DAC at 30 GPa. The sample was laser heated to 1600 degrees C in several spots (orange circles) to perform direct transformation to perovskite and (Mg,Fe)O. Portions of this work conducted at The Advanced Photon Source, GSECARS, 13 IDD.
