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.

New Argonne Site Access Requirements Take Effect September 20, 2021

Click the following links for additional info:
For Collaborative Access Team (CAT) operations staff to the Advanced Photon Source
For general users and non-experimental access to the Advanced Photon Source

Current APS guidance for the 2021-2 and 2021-3 runs mandate that external users are only allowed onsite with APS approval. An onsite user must have ANL site access approval, complete all APS required safety courses and complete the On-Site User Request Form (https://www.aps.anl.gov/form/on-site-user-request-form).  After onsite approval is received, the ESAF for the experiment will be approved. 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 required to have approved ANL site access and must complete APS safety course ESH223

Contacting beamline staff prior to your experiment is required.  This can be arranged either via email, phone, or online (Zoom or Bluejeans platforms 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.
Send samples to :

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.

National School on Neutron and X-ray Scattering (NX School)

GSECARS beamline scientists Joanne Stubbs, Peter Eng, Matt Newville, and Tony Lanzirotti hosted graduate students at the virtual NX School on July 20 and 22, 2021. At 13 ID-E, arabidopsis seeds were analyzed using X-ray fluorescence and fluorescence computed tomography. At 13 ID-C, crystal truncation rods were measured from the surface of hematite single crystals under helium gas.

Smiley Users are Back On-Site

Smiley Users are Back On-Site

Yet another exciting run has come to an end for the DAC program at 13-IDD and 13-BMD. We were thrilled to work with all our users remotely and on-site and be part of their breathtaking experiments, pushing the pressure and temperature limits to over 160 DACs. We look forward to welcome all users back at GSECARS on the 2021-3 run!
