Acquisition of an EBSD system for phase and crystallographic orientation mapping of earth and planetary materials

加州大学圣地亚哥分校的斯克里普斯海洋研究所（SIO）将获得一台电子后向散射衍射探测器，该探测器将与一台新的场发射扫描电子显微镜相结合。由此产生的尖端仪器将被安置在加州大学圣地亚哥分校的材料研究中心，该中心为SIO研究人员提供全面的技术支持和优先访问权。该仪器是PIs研究变形微观结构和地球化学耦合过程的核心。额外的功能也将使其他SIO地球科学研究人员受益，并且通常可供UCSD研究人员使用。预计将促进地球科学家和行星科学家之间的跨学科合作，并使材料科学家受益。新仪器也将成为一门课程的重点，该课程为学生准备材料表征，这对学术界和工业界的成功至关重要。该项目将使斯克里普斯海洋学研究所获得EBSD（电子背散射衍射）仪器，该仪器将与全新的，最先进的场发射SEM（扫描电子显微镜）相结合。EBSD是中国科学院下地壳地球化学和流变演化耦合研究和俯冲带壳幔压力-温度-时间历史研究的重要组成部分。此外，EBSD将被SIO和加州大学圣地亚哥分校的其他几位研究人员用于从美国国家科学基金会资助的地表环境到行星深层内部的研究。材料表征课程将使用尖端仪器作为实践学习和重要技术培训和技能集的焦点，为学生在学术界和工业界的竞争力做好准备。

Scripps Institution of Oceanography (SIO) at the University of California at San Diego will acquire an electron backscatter diffraction detector that will be coupled to a new Field Emission Scanning Electron Microscope. The resulting, cutting-edge instrument will be housed at UC San Diego's Materials Research Center which provides full technical support and priority access for SIO researchers. The instrument is central to the PIs research into processes that couple deformation microstructures and geochemistry. The additional capabilities will also benefit several other SIO geoscience researchers as well as be generally available to UCSD researchers. It is expected to promote interdisciplinary collaborations among geoscientists and planetary scientists as well as benefitting materials scientist. The new instrument will also be the focus of a course that prepares students in the materials characterization that is essential for success in academia and industry.This project will enable Scripps Institution of Oceanography to acquire EBSD (electron backscatter diffraction) instrumentation, which will be coupled with a brand new, state-of-the-art field emission SEM (scanning electron microscope). EBSD is an integral component of the PI's research on 1) the coupled geochemical and rheological evolution of lower crust and 2) understanding the pressure-temperature-time history of subduction zone crust and mantle. In addition, the EBSD will be utilized by several other SIO and UC San Diego researchers for applications ranging from NSF-funded studies of the surficial environment to planetary deep interiors. Courses on materials characterization will use the cutting edge instrument as a focal point for hands-on learning and important technical training and skill sets that prepare students to be competitive in academia and industry.
