Acquisition of a Field Emission Environmental Scanning Electron Microscope for Multidisciplinary Research Projects at UIUC

该项目包括购买、安装和使用一台环境扫描电子显微镜，该显微镜将安置在伊利诺伊大学香槟分校贝克曼研究所的显微镜套件设施中。所要求的仪器将提供唯一的访问环境扫描电镜和唯一的仪器可用于UIUC校园内的生物研究。该仪器提供了一种独特的能力，可以在样品室的残余气体压力范围内使用场发射源电子束检查样品，该压力范围可以超过饱和水蒸气压力。因此，含水的样品可以在没有事先干燥的情况下观察。该仪器将被20多个研究小组使用，涉及范围广泛的研究，包括生物材料、植物地衣、昆虫触角组织和纺织品。

This project involves the purchase, installation and use of an Environmental Scanning Electron Microscope to be housed in the Microscopy Suite Facility of the Beckman Institute at the University of Illinois, Champaign. The requested instrument will provide the only access to environmental SEM and the only instrument available for biological research on the UIUC campus. This instrument provides the unique capability for examining specimens with a field emission source electron beam at a residual gas pressure range in the specimen chamber which can exceed the saturated water vapor pressure. Thus, water-containing samples can be viewed without prior drying. The instrument will be used by over 20 research groups involved in a broad range of research including biomaterials, plant lichens, insect antennal tissue and textiles.
