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. ***

0521653 Cashman这主要研究仪器（MRI）计划资助支持在俄勒冈州大学的可变压力扫描电子显微镜（VP-SEM）的收购。 VP-SEM将被安置在地质科学系，并可通过俄勒冈州（CAMCOR）的先进材料表征中心在校园和区域范围内供研究和学生使用。 一个新的VP-SEM将取代现有的，但老化（13岁）JEOL 6300扫描电子显微镜。 具有几个电子问题和大大降低的能力。 火山学、实验岩石学、矿石岩石学、古土壤学和材料科学的研究将利用VP-SEM对稀有样品进行成像（例如，该系统包括一个用于确定多晶材料取向统计数据的电子背散射衍射系统（EBSD），该系统用于确定多晶材料的取向统计数据，用于确定地质材料和新型热电和半导体材料的取向统计数据。 VP-SEM将服务于地质学及相关科学的本科生、研究生和博士后水平的研究培训和教育目标，并将免费向太平洋西北地区四年制学院的学生和研究人员开放供外部使用。每年作为拟议夏季“野外活动日”计划的一部分。 ***
