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, wmao [at] stanford [dot] edu (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.
