2021 APSUO Arthur H. Compton Award

Congratulations to Dr. Mark Rivers and Dr. Stephen Sutton as the recipients of the 2021 APSUO Arthur H. Compton Award. The award recognizes a significant scientific or technical accomplishment at the Advanced Photon Source.

GSECARS Developed an Efficient and Affordable N95 Mask Disinfection System

Dr. Peter Eng with help from Mike Proskey and Dr. Joanne Stubbs, developed an efficient system of disinfecting N95 masks in large quantities.  This system will be invaluable for hospitals, factories, schools and offices as America re-opens during the current health crisis.

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.

Tomography at 13 BMD

A. Herring, OSU, uses tomography at 13 BMD to quantify pore scale trapping and to analyze how mechanisms affect the efficiency of capillary trapping of CO2 in saline aquifers.

Update on status and plans at GSECARS, August 25, 2020

Please note the following information:
Current APS guidance for the 2021-1 and 2021-2 runs mandates that external users will not be allowed on-site.  Based on this current policy, GSECARS is only scheduling users for 2021-1 and 2021-2 that can mail-in samples, with partial or full remote access to control selected beamline computers to perform experiments in-close collaboration with GSECARS beamline staff.

Users that wish to have remote computer access to run their experiments at GSECARS will be considered “Remote Users” and noted so on their ESAF.  “Remote Users” are still required to have all their APS safety training up to date for ESAF approval, ANL site access must be current and an approved 593 in place for foreign nationals.

Contacting beamline staff prior to your experiment is required.  This can be arranged either via email, phone, or online (Zoom or Bluejeans are preferred).

Samples should be sent to your primary beamline contact at least one week ahead of scheduled beamtime.  Please send the shipment tracking number to your host.  We recommend FedEx as the most reliable option for shipping samples.

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
