  • Radial diffraction in DAC elastic anisotropy,
    strain and stress, yield strength, preferred
    orientation etc.
  • One key goal of the workshop
  • Sharing the experience from experts in DAC radial
    diffraction. DAC design, gasket optimization,
    sample preparation, data collection and analysis.
  • Develop the challenging project of rheological
    studies
  • Combining different heating methods with radial
    diffraction technique
  • Gasket techniques Be, (Kapton, amorphous boron,
    and epoxy), others
  • Theoretical modeling and analysis improvement
  • New techniques rotational DAC and dynamic DAC.

Benefit to COMPRES Community
1. Pushing the technological frontier of rheology
study in DAC 2. Broadening the COMPRES
community access to the DAC radial diffraction.
The experts of DAC design, beamline scientists,
structural refinement experts, rheology experts
and potential users will assemble together to
determine the way to coordinate the above efforts
efficiently. Infrastructure proposal
Rheology in DAC (tentative title) will be
submitted to COMPRES by a cooperative,
multi-institutional team based on the discussions
and feedbacks in this workshop
