description

  • Carbon-specific X-ray Raman spectroscopy (XRS) is the most definitive probe for in-situ, non-destructive characterization of the ubiquitous, significant changes in carbon-molecular bonding under high-pressure and high-temperature conditions. The DCO provided partial support for a Kirkpatrick-Baez (K-B) focusing system (pictured) that enables high-pressure carbon-specific XRS study at Beamline 6-2 of the Stanford Synchrotron Radiation Laboratory (SSRL), SLAC National Accelerator Laboratory. This new development opens the exciting capability of XRS to a broader community than ever before.

    The instrument was commissioned in April 2012 and optimization and improvements are ongoing. According to Principal investigator, Wendy Mao, the system is fully operational and open to the DCO community for use in x-ray spectroscopy experiments. The K-B focusing system’s construction was partially funded by the DCO and is one component of an ambitious five-year project that is supported in conjunction with the U.S. Department of Energy (DOE). The entire project will ultimately cost approximately $20 million with $3 million per year in operating expenses.
