项目摘要

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.

加州大学圣地亚哥分校斯克里普斯海洋学研究所 (SIO) 将购买一台电子背散射衍射探测器，该探测器将与新型场发射扫描电子显微镜相结合。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使用权。该仪器是 PI 研究变形微观结构和地球化学耦合过程的核心。这些额外的功能也将使其他几位 SIO 地球科学研究人员受益，并且普遍可供加州大学圣地亚哥分校的研究人员使用。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。新仪器也将成为一门课程的重点，该课程帮助学生做好材料表征方面的准备，这对于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能够获得 EBSD（电子背散射衍射）仪器，该仪器将与配备全新、最先进的场发射 SEM（扫描电子显微镜）。 EBSD 是 PI 研究的一个组成部分：1) 下地壳的耦合地球化学和流变演化；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 SIO 和加州大学圣地亚哥分校的其他几位研究人员用于从 NSF 资助的地表环境研究到行星深层内部研究等各种应用。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组合的焦点，使学生在学术界和工业界具有竞争力。
