GSECARS Scientists Continue to Decode Moon's Mysteries 50 Years Later

Celebrating the 50th anniversary of the Apollo 11 moon landing, Argonne explores its early lunar research as it anticipates studies at the Advanced Photon Source of pristine moon rocks from the final lunar landing missions.

Diffraction at 13 BMC

Jin Zhang, an assistant professor in The University of New Mexico’s Department of Earth and Planetary Sciences, was recently awarded a NSF CAREER grant to pursue new research on the elastic anisotropy of mantle minerals and potential relationships with mantle flows.  Pictured here at 13 BMC.

Pockets of water may lay deep below Earth’s surface.

GSECARS Outreach

GSECARS hosts experiments at 13 IDE for high school students in the Exemplary Student Research Program (ESRP) representing local area high schools.

X-ray Diffraction Patterns from a Diamond Anvil Cell.

X-ray diffraction is the most powerful technique for crystal structure determination. From left to right, patterns from a single crystal, polychrystalline, nano-cyrstalline and amorphous crystals.

Paris-Edinburg Press

The 180 ton Paris-Edinburg press combined with a multi-channel collimator to study structures of liquid silicates up to 12 GPa and 3000 K in 13-ID-C. The intense double focused monochromatic beam allows collection of X-ray scattering patterns with robust statistics in 5 minutes.

13 IDE new mirrors

13 IDE new mirrors achieve focused spot sizes in both the vertical and horizontal direction of <500 nm.

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.
