MRI: Acquisition of a DualBeam FIB/SEM

0923127Fei：“本奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。”在提交给主要研究仪器（MRI）计划的提案中，pi要求48万美元用于购买材料表征设备。请求一种双光束FIB/SEM（聚焦离子束/扫描电子显微镜）系统。该仪器将安装在靠近扫描电镜的现有空间中。该机构将提供翻新资金。一名专职微光束专家和一名兼职电子工程师将负责维护和操作。微光束专家将负责现场新用户培训。使用将由FIB委员会分配，该委员会还将通过机构资金、赠款和使用费确定用户费率并管理维修费用。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，如高压矿物物理实验，天然金刚石和熔融包裹体，大气有机质和前太阳颗粒，以及CVD单晶金刚石。通过FIB/SEM的微/纳米制造技术，金刚石砧的性能将得到提高。FIB/SEM将对正在进行的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的研究起到重要的补充作用。该仪器将满足区域和社区的需要。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。将有一个强大的接口与compes。培训将提供给所有用户，此次收购将加强多个跨学科研究项目，培养未来的SEM和高压物理科学家。＊＊＊

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. ***
