0003529OlsenThis grant provides 70% support of the costs of acquiring a modern software-based scanning electron microscope (SEM), energy-dispersive X-ray microanalyzer (EDX), and new sample preparation equipment for Lamont-Doherty Earth Observatory to replace the aging analogue units jointly funded by NSF and ONR in 1983-1984. The combined remaining 30% is contributed by Lamont, Columbia University, and the American Museum of Natural History. The eight Principal Investigators, led by P. Olsen of Lamont and including the Facility Manager (D. Breger), represent a range of multidisciplinary users from the three participating institutions. In addition to providing traditional high vacuum/high voltage imaging and analysis of conductive dry samples, the new system will allow low vacuum and low voltage operation, imaging of hydrated and uncoated samples, and X-ray mapping. While primarily dedicated to the earth sciences, the reinvigorated Facility will follow the successful open approach of the current Facility, which is available to academic users from any discipline or institution.The new system will directly benefit numerous current and future research programs of a large number of scientists as well as the education and training of students in the earth sciences, materials sciences, engineering, and other fields. This variety of use will have far-ranging impact for advancing knowledge in a number of intended and unforeseen directions and promote interdisciplinary and inter-institutional collaborations. Formal academic coursework utilizing this Facility will be developed, including online. Public outreach and K-12 school programs will continue to expand current activities. The new instrumentation and equipment will be housed in Lamont's existing Electron Optics Laboratory complex under continued management by Breger. This complex has been dedicated to electron microscopy since 1969 and is optimized for the purpose. Support for this grant is shared by the Earth Sciences Instrumentation and Facilities Program (EAR/IF), the Division of Ocean Sciences' Oceanographic Instrumentation and Technical Service Program (OCE/ITS) and the Marine Geology and Geophysics Program (OCE/MGG).***

0003529 Olsen这笔赠款提供70%的支持，用于为Lamont-Doherty地球天文台购买基于软件的现代扫描电子显微镜（SEM），能量色散X射线显微分析仪（EDX）和新的样品制备设备，以取代1983-1984年由NSF和ONR共同资助的老化模拟装置。 剩下的30%由拉蒙、哥伦比亚大学和美国自然历史博物馆共同出资。 由拉蒙的P.奥尔森领导的八名主要调查员，包括设施经理（D. Breger），代表了来自三个参与机构的一系列多学科用户。 除了提供传统的高真空/高电压成像和导电干样品的分析，新系统将允许低真空和低电压操作，水合和无涂层样品的成像和X射线映射。虽然主要致力于地球科学，但重新焕发活力的设施将遵循现有设施的成功开放方法，可供任何学科或机构的学术用户使用。新系统将直接受益于大量科学家的许多当前和未来研究计划，以及地球科学，材料科学，工程和其他领域学生的教育和培训。 这种多样性的使用将对在一些预期和不可预见的方向上推进知识产生深远的影响，并促进跨学科和机构间的合作。 将利用这一设施开发正式的学术课程，包括在线课程。公共宣传和K-12学校项目将继续扩大当前的活动。 新的仪器和设备将被安置在拉蒙现有的电子光学实验室综合体，由Breger继续管理。 自1969年以来，该复合体一直致力于电子显微镜，并为此目的进行了优化。 对这项赠款的支持是由地球科学仪器和设施计划（OCE/IF），海洋科学海洋仪器和技术服务计划（OCE/ITS）和海洋地质学和地球物理学计划（OCE/MGG）。
