Earthquakes, volcanoes, and impact craters demonstrate the dynamic processes active within the Earth and other bodies in the solar system. Observations of these events alone are not enough to the underlying physics at play. Laboratory experiments on Earth materials are essential to better understand geological, geophysical, and geochemical observations. This Research Coordination Network (RCN) provides the means for the researchers with a broad range of backgrounds in Earth science and engineering to explore new technologies that are available through high-energy X-ray facilities. This RCN will foster international collaborations from different scientific communities and engage the next generation of scientists. The broader impacts of the project include the participation of women and under-represented groups in STEM fields. It will also lay the foundation for new experimental infrastructure in rock deformation. These efforts have wide-reaching applications in basic and applied research, from topics like hazard mitigation to energy resources and space exploration.This RCN will facilitate the integration of beamline technologies with deformation experiments and create new directions for experimental rock deformation research. Predictions and inferences of geodynamic processes require extrapolation of lab-calibrated rheological models to geological time and spatial scales that are many orders of magnitude larger than in the laboratory. The complexity of rock deformation processes together with the uncertainties inherent in using existing techniques make extrapolating laboratory-derived rheological models to larger-scale deformation challenging. Through the network, U.S. researchers will 1) identify knowledge gaps in rock deformation that hinder our understanding of geological and geophysical processes; 2) provide training and education opportunities for a diverse group of experimentalists to gain necessary knowledge about beamline technologies, and for beamline scientists to recognize the needs and constraints associated with deformation research on geomaterials; 3) promote the discussion of expanding the infrastructure for experimental research; and 4) foster collaborations across disciplines to develop new experimental methodologies for studying dynamic processes at various time scales. The RCN will also lay the foundation for new experimental infrastructure development for rock deformation within national radiation research centers. New data streams from these efforts will have wide-reaching applications in basic and applied research, on topics ranging from hazard mitigation, to energy resources, to space exploration, and beyond. This project is supported by the Geophysics, Tectonics, GeoPRISMS and Instrumentation and Facilities programs.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

地震，火山和冲击火山口证明了地球和太阳系中其他物体的动态过程。仅对这些事件的观察不足以使其在发挥作用的基础物理学。在地球材料上进行的实验室实验对于更好地了解地质，地球物理和地球化学观测至关重要。该研究协调网络（RCN）为具有广泛背景的研究人员提供了地球科学和工程背景的手段，以探索可通过高能量X射线设施获得的新技术。该RCN将促进来自不同科学社区的国际合作，并参与下一代科学家。该项目的更广泛影响包括妇女和代表性不足的群体参与STEM领域。它还将为岩石变形中的新实验基础设施奠定基础。这些努力在基础和应用研究中具有广泛的应用，从危害危险等主题到能源资源和太空探索。此RCN将促进光束线技术与变形实验的整合，并为实验岩石变形研究创建新的方向。地球动力学过程的预测和推断需要将实验室校准的流变模型推送到地质时间和空间尺度上，这些尺度比实验室大的数量级。岩石变形过程的复杂性以及使用现有技术固有的不确定性使外推实验室衍生的流变学模型挑战了更大尺度的变形。通过网络，美国研究人员将1）确定岩石变形中的知识差距，从而阻碍了我们对地质和地球物理过程的理解； 2）为各种各样的实验者提供培训和教育机会，以获取有关光束线技术的必要知识，并使光束线科学家认识到与地质材料的变形研究相关的需求和约束； 3）促进有关扩大基础设施进行实验研究的讨论； 4）培养跨学科的合作，以开发新的实验方法，以在不同时间尺度研究动态过程。 RCN还将为国家辐射研究中心内岩石变形的新实验基础设施发展奠定基础。这些努力的新数据流将在基础研究和应用研究中具有广泛的应用程序，包括危害减轻，能源资源，太空探索以及其他方面的主题。该项目得到了地球物理，构造学，地质主义，仪器和设施计划的支持。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的审查标准，认为值得通过评估来获得支持。
