The project is for the University of Minnesota to acquire a next-generation electron microprobe to replace a well-used but aging 23-year-old instrument. This investment provides the newest capabilities in high-resolution mapping of elements in rocks, organic material, and high-technology materials. This support is congruent with NSFs mission of promoting the progress of science and advancing the national health, prosperity and welfare, given the importance of expanding the frontiers of knowledge in the earth and environmental sciences, engineering, archeology, biotechnology and dentistry. The new instrument serves a national research community as well as universities in Minnesota, western Wisconsin, the Dakotas, and Montana.The University of Minnesota will acquire a next-generation electron microprobe, which houses multiple energy-dispersive spectrometers, including a Soft X-ray Emission Spectrometer (SXES). The instrument means that elements can be mapped at a high-spatial resolution of 200 nanometers. The SXES provides for a new capability in the analysis of light elements and organic matter, phosphates, carbonates, and polymers. Research programs at Minnesota that depend on electron microprobe analyses include experimental petrology, mineral and rock physics, geobiology, geomicrobiology, and bioremediation, tectonics and metamorphic petrology, mineral and rock magnetism, aqueous geochemistry, paleoclimate, and economic geology.

该项目是为了让明尼苏达大学购买下一代电子探针，以取代使用良好但老化的23年历史的乐器。这项投资提供了岩石，有机材料和高科技材料中元素的高分辨率映射的最新功能。 鉴于扩大地球和环境科学，工程，考古学，生物技术和牙科的重要性，这种支持与NSFS的使命相一致，即NSFS的使命是促进科学的进步和推进国家健康，繁荣和福利。 新乐器为国家研究界以及明尼苏达州，威斯康星州西部，达科他州和蒙大拿州的大学提供服务。明尼苏达大学将获得下一代电子微探针，其中包含多个能量分散性光谱仪，包括软X射线发射光谱仪（SXES）。 该仪器意味着可以以200纳米的高空间分辨率映射元素。 SXES在分析光元素和有机物，磷酸盐，碳酸盐和聚合物方面具有新的能力。明尼苏达州的研究计划依赖于电子微探针分析，包括实验性岩石学，矿物质和岩石物理学，地球生物学，地球生物学以及生物修复，构造和变质岩石学，矿物质和岩石学，岩石磁力，水，地球化学，古气候和经济地理学。
