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)将获得一个电子背向散射衍射探测器，该探测器将与新场发射扫描电子显微镜相耦合。由此产生的尖端仪器将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限。该仪器是PIS研究变形微结构和地球化学耦合过程的核心。这些额外的能力也将使其他几个SIO地球科学研究人员受益，并普遍适用于加州大学圣迭戈分校的研究人员。预计它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。新的仪器也将是一门课程的重点，该课程旨在培养学生在学术界和工业界取得成功所必需的材料表征。该项目将使斯克里普斯海洋研究所获得EBSD(电子背向散射衍射)仪器，该仪器将与全新的、最先进的场发射扫描电子显微镜(扫描电子显微镜)相结合。EBSD是PI研究的一个组成部分，其研究内容包括：1)下地壳的地球化学和流变学耦合演化；2)了解俯冲带、地壳和地幔的压力-温度-时间历史。此外，EBSD将被其他几个SIO和加州大学圣地亚哥分校的研究人员用于从NSF资助的表面环境研究到行星内部深处的各种应用。有关材料特性的课程将使用尖端仪器作为实践学习的焦点，并提供重要的技术培训和技能集，为学生在学术界和工业中具有竞争力做准备。

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.
