Acquisition of a Variable Pressure Scanning Electron Microscope

本主要研究仪器（MRI）计划资助俄勒冈大学购置一台变压扫描电子显微镜（VP-SEM）。VP-SEM将被安置在地质科学系，并可通过俄勒冈州先进材料表征中心（CAMCOR）在校园和整个地区进行研究和学生使用。新的VP-SEM将取代现有的老化（13年）JEOL 6300扫描电子显微镜。有几个电子问题，性能大大降低。火山学、实验岩石学、矿石岩石学、古岩石学和材料科学的研究将利用VP-SEM成像稀有样品（例如，陨石、化石和人工制品的博物馆标本），而不需要初步的碳或金涂层。以及附加的电子背散射衍射系统（EBSD），用于确定地质和新型热电和半导体材料的多晶材料的取向统计。VP-SEM将为地质学和相关科学的本科生、研究生和博士后提供研究培训和教育目标，并将作为拟议中的夏季“实地考察日”项目的一部分，每年向太平洋西北地区四年制大学的学生和研究人员免费开放。＊＊＊

0521653CashmanThis Major Research Instrumentation (MRI) Program grant supports acquisition of a variable pressure scanning electron microscope (VP-SEM) at the University of Oregon. The VP-SEM will be housed in the Department of Geological Sciences and available for research and student use both on campus and region-wide through the Center for Advanced Materials Characterization in Oregon (CAMCOR). A new VP-SEM will replace an existing but aging (13 years old) JEOL 6300 scanning electron microscope. with several electronics problems and greatly reduced capabilities. Studies in volcanology, experimental petrology, ore petrology, paleopedology, and materials science will take advantage of the VP-SEM for imaging rare samples (e.g., museum specimens of meteorites, fossils, and artifacts) without requiring preliminary carbon or gold coating, and an additional electron backscattered diffraction system (EBSD) to be purchased for determining orientation statistics of polycrystalline materials for both geological and novel thermoelectric and semiconductor materials. The VP-SEM will serve research training and education goals at the undergraduate, graduate and post-doctoral levels in Geology and related sciences and will be open for outside use to students and researchers from four-year colleges in the Pacific Northwest at no charge each year as part of a proposed summer "field day" program. ***
