UPGRADE OF ELECTRON MICROPROBE SX-100 AT OREGON STATE UNIVERSITY IN THE COLLEGE OF EARTH, OCEAN, AND ATMOSPHERIC SCIENCES

该地球科学部仪器和设施项目支持老化的2004 CAMECA SX-100电子微探针的升级。俄勒冈州立大学（OSU）电子探针（EMP）实验室是一个开放的分析设施，用于广泛的科学研究，以及本科生和研究生的研究和教育。该奖项还得到了海洋科学部海洋地质和地球物理项目的联合支持。电子探针是一种研究工具，能够确定固体材料的微空间分解化学成分，帮助研究人员解决各种各样的科学和工程问题。这些问题包括地质、冶金、固体物理、机械和化学工程、电子、生物和物理化学等领域的问题。该实验室已成为俄勒冈州立大学研究基础设施的重要组成部分，并支持各种用户群的研究活动，包括地球科学家、工程师、生物学家、材料科学家和环境科学家。EMP的升级将为整个俄勒冈州立大学社区、其他学术机构、州和联邦机构以及大量国内和国际的行业合作者和合作伙伴提供不可或缺的服务。OSU电子探针的升级是必要的，有几个原因：1)目前的设备已经超过15年，并且正在经历性能下降和间歇性问题，电子元件，光谱仪和真空系统；2)一台功能齐全的机器将使教职员工和学生能够满足俄勒冈州立大学目前对电子显微探针分析的需求，为研究生和本科生提供更多的用户访问，并改善和增加动手实验室体验；3)电子探针将为岩浆成因、分化和火山灾害研究、新元古代和早古生代动物化石过程的古生物学研究以及小行星物质热史和撞击史研究提供重要动力。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This Division of Earth Sciences Instrumentation and Facilities program award supports upgrade of an aging 2004 CAMECA SX-100 electron microprobe. The Oregon State University (OSU) Electron Microprobe (EMP) Laboratory is an open analytical facility and is used for research across a broad spectrum of sciences, and for undergraduate and graduate student research and education. The award is also jointly supported by the Division of Ocean Sciences Marine Geology and Geophysics Program. The electron microprobe is a research tool capable of determining microspatially resolved chemical compositions of solid materials that help researchers address a wide variety of scientific and engineering problems. These include problems in the fields of geology, metallurgy, solid state physics, mechanical and chemical engineering, electronics, biology, and physical chemistry. The laboratory has formed an important component of the OSU research infrastructure and underpins the research activities of a diverse user base, including geoscientists, engineers, biologists, material scientists and environmental scientists.Upgrade of the EMP will provide indispensable services to the entire OSU community, to other academic institutions, state and federal agencies, and to a large number of industry collaborators and partners both nationally and internationally. Upgrade of the OSU electron microprobe is necessary for several reasons: 1) the current equipment is now over 15 years old and is experiencing reduced performance and intermittent problems with electronic components, spectrometers and vacuum systems; 2) a full-functioning machine will allow faculty and students to meet current demands for electron microprobe analyses at OSU, providing increased user access, and improving and increasing hands-on laboratory experiences for graduate and undergraduate students; and 3) upgrading the EMP our electron microprobe will provide an important impetus for future research activities including studies of magma genesis, differentiation and volcanic hazards, paleontological investigations of Neoproterozoic and early Paleozoic animal fossilization processes, and studies of the thermal and impact history of asteroid materials.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
