CHESS recently hosted the first of a series of workshops associated with the NSF-funded 'In-situ Studies of Rock Deformation' Research Collaborative Network (RCN). The goal of this Research Collaborative Network is to poise the rock deformation community to take advantage of emerging beamline technologies (both X-ray and neutron based) to revolutionize the testing and calibration of deformation models through direct measurements of microstructural and micromechanical evolution of rock deformation during realistic loading conditions. The workshops hosted as part of this RCN aim to bring together geophysicists and beamline scientists to chart a path forward for the development of new measurement capabilities and experiments. The workshop at CHESS brought together over 130 researchers from industry, national laboratories, and academia to learn more about high-energy X-ray imaging and diffraction capabilities for studying rock deformation and to learn about pressing scientific challenges for the rock deformation community. Nine invited speakers from a diverse research background presented outstanding questions in geophysics and introduced recent advances of beamline technology to the participants. The workshop also highlighted capabilities developed at CHESS to elucidate structure-processing-properties-performance relationships in structural materials at the Forming and Shaping Technology (FAST) Beamline and the Structural Materials Beamline (SMB) that can be applied to rock deformation studies. The workshop ended with a series of discussions synthesizing the findings of the workshop. Click here to view the talks at the CHESS workshop and learn more about future RCN activities.
