0923127Fei"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)." In this proposal submitted to the Major Research Instrumentation (MRI) Program, the PIs request $480K to acquire materials characterization equipment. Requested is a dual beam FIB/SEM (focused ion beam/scanning electron microscope) system. The instrument will be outfitted in existing space in proximity to the SEM. The institution will provide renovation funding. A full-time, dedicated microbeam specialist and a part-time electronics engineer will oversee maintenance and operation. The microbeam specialist will be responsible for on-site new user training. Usage will be allocated by an FIB committee which will also set user rates and administer maintenance costs through institutional funds, grants and user fees. The instrumentation will assist in sample characterization, sample preparation and micro/nano fabrication. It will support multiple projects allowing investigators to characterize small samples from various sources such as high-pressure mineral physics experiments, natural diamond and melt inclusions, meteoric organic matter and pre-solar grains, and CVD single crystal diamond. Diamond anvil performance will be enhanced through micro/nano-fabrication efforts targeted at cell assembly design made possible by the FIB/SEM. The FIB/SEM will be a critical addition to ongoing studies in cosmochemistry and astrobiology, organic geochemistry and ancient biochemistry, inorganic geochemistry and petrology, and high pressure geophysics. The instrumentation will serve a regional and community need. Due to the institutional support, the instrument will operate effectively and allowing high-precision analysis by researchers (students, post-docs, PIs) of all skill levels. There will be a strong interfacing with COMPRES. Training will be made available to all users and this acquisition will enhance multiple interdisciplinary research projects and train future SEM and high pressure physics scientists. ***

0923127Fei“该奖项是根据 2009 年美国复苏和再投资法案（公法 111-5）提供资金的。”在提交给主要研究仪器 (MRI) 计划的提案中，PI 请求 48 万美元购买材料表征设备。要求的是双束 FIB/SEM（聚焦离子束/扫描电子显微镜）系统。该仪器将安装在 SEM 附近的现有空间中。该机构将提供翻新资金。一名全职、专门的微束专家和一名兼职电子工程师将负责监督维护和操作。微束专家将负责现场新用户培训。使用量将由 FIB 委员会分配，该委员会还将通过机构资金、赠款和使用费来设定用户费率并管理维护成本。该仪器将有助于样品表征、样品制备和微/纳米制造。它将支持多个项目，使研究人员能够表征来自各种来源的小样本，例如高压矿物物理实验、天然钻石和熔体包裹体、流星有机物和前太阳颗粒以及 CVD 单晶钻石。通过 FIB/SEM 实现的针对电池组装设计的微/纳米制造工作，将提高金刚石砧的性能。 FIB/SEM 将成为宇宙化学和天体生物学、有机地球化学和古代生物化学、无机地球化学和岩石学以及高压地球物理学等领域正在进行的研究的重要补充。该仪器将满足地区和社区的需求。由于机构的支持，该仪器将有效运行，并允许所有技能水平的研究人员（学生、博士后、PI）进行高精度分析。与 COMPRES 之间将有一个强大的接口。培训将为所有用户提供，此次收购将加强多个跨学科研究项目，并培训未来的 SEM 和高压物理科学家。 ***
