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.

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

Jim Viccaro Farewell
More than 50 members of the University of Chicago and Argonne National Laboratory communites gathered at the Argonne Guest House on April 22nd for a Retirement Luncheon in honor of P. James Viccaro. Jim's career was celebrated for his vital roles in the development of the Advanced Photon Source at ANL and the Center for Advanced Radiation Sources at The Unviersity of Chicago. Jim was Executive Director of CARS from 2003 until 2013.
