MRI: Acquisition of a Variable-pressure Scanning Electron Microscope for Interdisciplinary Teaching and Research at the University of Minnesota-Duluth

该项目获得了一台变压扫描电子显微镜(SEM)，用于地球科学、生物学和工程学的研究和教学。该仪器将用于材料的高级形态、纹理和成分表征。由于能够在低真空和高真空下工作，可变压力扫描电子显微镜允许对干材料和湿生物样品进行成像。除了背向散射和二次电子探测器外，该仪器还将配备能量色散X射线分析系统(EDS)、阴极发光成像系统(CL)、电子背向散射衍射仪(EBSD)和低真空二次电子探测器(ESED)。就更广泛的影响而言，该仪器将是明尼苏达州北部的第一个此类仪器。它将被广泛用于学生研究和教育，以及发展行业合作伙伴关系。

This project acquires a variable-pressure scanning electron microscope (SEM) for research and education in the earth sciences, biology, and engineering. This instrument will be used for advanced morphological, textural and compositional characterization of materials. With the ability to work under both low- and high-vacuum, the variable-pressure SEM allows for imaging of both dry materials and wet biological samples. In addition to back-scattered and secondary electron detectors, the instrument will be equipped with an energy-dispersive x-ray analysis system (EDS), cathodoluminescence imaging system (CL), electron back-scatter diffractometer (EBSD), and low-vacuum secondary-electron detector (ESED). In terms of broader impacts, this instrument will be the first of its kind in northern Minnesota. It will be used extensively for student research and education, as well as development of industry partnerships.
