Report on COMPRES Workshop: Envisioning the Next Generation of In-situ Synchrotron X-ray Techniques in Large-Volume High Pressure Apparatus for Mineral and Rock Physics
On September 28-30, 2018 a COMPRES sponsored workshop entitled “Envisioning the Next Generation of In-situ Synchrotron X-ray Techniques in Large-Volume High Pressure Apparatus for Mineral and Rock Physics” was held at the Advanced Photon Source, Argonne National Lab. The goal of the workshop was to explore how cutting-edge synchrotron techniques, including those that can characterize 3D distributions of properties and micromechanical response such as phase, density, crystallographic orientation or stress states, can be integrated into large volume apparatus experiments. Workshop participants learned about the current state of the art in synchrotron-based rock deformation experiments and in-situ tomographic imaging of features with contrasting density such as fractures and melts. Participants also learned about the current state of the art in 3D mapping of grain morphology, orientation, and stress states via high energy diffraction microscopy (HEDM), the 3D mapping of phase distribution using diffraction tomography, absorption computed tomography and energy dispersive x-ray diffraction. These techniques are currently being utilized to characterize the distribution and evolution of phases in materials from bones to batteries and the 3D distribution of stresses in metals as they are being deformed. Speakers from a broad spectrum of rock physics and deformation specializations talked about problems in their research areas that could potentially be solved with in-situ observations. Brain storming sessions identified first experiments, new collaborations and future directions. One of the results of the workshop was the decision to seek funding for an NSF Research Coordination Network grant that would facilitate continued dialog, future small and large workshops and additional efforts to push this new area of science forward. Wenlu Zhu was chosen to head up the new RCN effort. The full agenda as well as talks presented at the workshop are available at http://www.largevolumercn.net.
The workshop was organized by Pamela Burnley, Haiyan Chen, William Durham, Shun Karato, Andreas Kronenberg, Donald Weidner, Matthew Whitaker, and Wenlu Zhu. APS site hosting were provided by Dr. Jonathan Almer, Ms. Linda Carlson with assistance from Dr. Yue Meng and Dr. Ke Yuan. Additional logistical support was provided by Mr. Richard Fenner, Mr. Barry Switzer, and Ms. Amy Mikuta from APS and Ms. Samantha Lin from Stony Brook University. Evening refreshments were provided by Rockland Research Corp.
