About CDAC

The Capital-DOE Alliance Center (CDAC) is a multisite, interdisciplinary center headquartered at The George Washington University in Washington, DC. Our goals are to advance and perfect an extensive set of high P-T techniques and unique facilities, to perform key studies on a broad range of important materials in newly-accessible P-T regimes, and to integrate and coordinate static, dynamic and theoretical results for Stewardship Science applications.

Principal Research Objectives

  • Measurement of highly accurate (± 1%) equation-of-state data in the multimegabar pressure range.
  • Determination of electronic and magnetic properties of solids and fluids to multimegabar pressures and elevated temperatures to bridge the bap between static and dynamic experiments.
  • Development of enabling techniques that will allow probes of the dispersion of phonons and electronic states in order to constrain theoretical calculations.
  • Directly determine the evolution of bonding and chemical kinetics at high pressure and temperature.
  • Extension of single-crystal structural refinements to the multimegabar pressure regime.
  • Carry out determinations of elastic constants and rheological properties of key materials at ultrahigh pressures and temperatures.
  • Reach megabar pressures with millimeter-sized samples.
  • Combine state-of-the-art static compression techniques with the latest laser technologies for generating high temperatures to realize the fullest possible coverage of high P-T space.
  • Radically change the status quo in high pressure-high temperature studies by conducting fundamental physical and chemical studies at high pressure and temperature with the same accuracy and understanding that we have achieved at ambient conditions.
