This award from the Instrumentation for Materials Research program to the University of California San Diego is for the acquisition and installation of a cold cathode field emission gun scanning electron microscope(FEG-SEM) with analytical capabilities for the Electron Microscopy Facility of the Materials Science Program, part of the Jacobs School of Engineering at the University of California San Diego (UCSD). The new instrument will enhance existing and new research projects currently active at UCSD in the engineering, physics and chemistry departments, as well as at the Scripps Institute of Oceanography. The FEG-SEM will provide high beam stability, low energy fluctuation, low beam current and high brightness in a range of accelerating voltages, features that are required for imaging nanoscale features in electronic, magnetic, optical, structural, organic and biological materials. The instrument will enhance both graduate and undergraduate research and education. The graduate students will benefit from hands-on exposure to a state-of-the-art microscope that will aid significantly in their research projects. Undergraduates will particularly benefit from this class, as it will be offered to upper division students who have a materials emphasis in their major program (currently available in mechanical, electrical, physics and chemistry departments).This award from the Instrumentation for Materials Research program to the University of California San Diego is for the acquisition and installation of a cold cathode field emission gun scanning electron microscope(FEG-SEM) with analytical capabilities for the Electron Microscopy Facility of the Materials Science Program, part of the Jacobs School of Engineering at the University of California San Diego (UCSD). The proposed equipment will replace the existing Cambridge 360 SEM, now 10 years old, and provide state-of-the-art capabilities. This system currently supports the research programs of faculty from departments and research units campus wide. The Materials Science Program will manage the new SEM and it will be available to all UCSD affiliated personnel and the outside community on an hourly fee basis. The new instrument will enhance existing and new research projects currently active at UCSD in the engineering, physics and chemistry departments, as well as at the Scripps Institute of Oceanography (SIO). The FEG-SEM will provide imaging of detailed structures coupled with the elemental analysis capabilities; it is a crucial tool for modern materials research and for training the next generation of engineers and scientists.The instrument will enhance both graduate and undergraduate research and education. The graduate and undergraduate students will benefit from hands-on exposure to a state-of-the-art microscope. A graduate level course in scanning electron microscopy will be introduced yearly into the Materials Science curriculum and will be available to all graduate students at UCSD and SIO. Undergraduates will particularly benefit from this class, as it will be offered to upper division students who have a materials emphasis in their major. In summary, the new instrument will provide a much-needed research and teaching tool by providing image and analytical capabilities not currently available to students on the UCSD campus.

该奖项是由材料研究仪器项目授予加州大学圣地亚哥分校的，目的是为材料科学项目的电子显微镜设施购买和安装具有分析能力的冷阴极场发射枪扫描电子显微镜（fg - sem），该项目是加州大学圣地亚哥分校雅各布工程学院（UCSD）的一部分。新仪器将加强目前在加州大学圣地亚哥分校工程、物理和化学系以及斯克里普斯海洋学研究所活跃的现有和新的研究项目。FEG-SEM将提供高光束稳定性、低能量波动、低光束电流和在加速电压范围内的高亮度，这些特征是成像电子、磁性、光学、结构、有机和生物材料的纳米级特征所必需的。该仪器将加强研究生和本科生的研究和教育。研究生将受益于亲身接触最先进的显微镜，这将有助于他们的研究项目。本科生将特别受益于这门课，因为它将提供给那些在主修课程中注重材料的高年级学生（目前在机械、电气、物理和化学院系提供）。该奖项是由材料研究仪器项目授予加州大学圣地亚哥分校的，目的是为材料科学项目的电子显微镜设施购买和安装具有分析能力的冷阴极场发射枪扫描电子显微镜（fg - sem），该项目是加州大学圣地亚哥分校雅各布工程学院（UCSD）的一部分。拟议中的设备将取代已有10年历史的剑桥360扫描电镜，并提供最先进的功能。该系统目前支持来自院系和研究单位的研究项目。材料科学项目将管理新的SEM，它将以小时收费的方式提供给加州大学圣地亚哥分校的所有附属人员和外部社区。新仪器将加强目前在加州大学圣地亚哥分校工程、物理和化学系以及斯克里普斯海洋学研究所（SIO）活跃的现有和新的研究项目。FEG-SEM将提供详细结构的成像以及元素分析能力；它是现代材料研究和培养下一代工程师和科学家的重要工具。该仪器将加强研究生和本科生的研究和教育。研究生和本科生将受益于亲身接触最先进的显微镜。研究生水平的扫描电子显微镜课程将每年引入材料科学课程，并将提供给加州大学圣地亚哥分校和SIO的所有研究生。本科生将特别受益于这门课，因为它将提供给那些在他们的专业中注重材料的高年级学生。总之，新仪器将提供加州大学圣地亚哥分校学生目前无法获得的图像和分析能力，从而提供急需的研究和教学工具。
