The acquisition of a new scanning electron microscope (SEM) will provide a major enhancement to the research infrastructure of the Institute of Meteoritics (IOM) and the Department of Earth and Planetary Sciences (EPS) at the University of New Mexico (UNM). The SEM will be integrated into the multidisciplinary research programs at UNM that serve the science community on campus and users from other universities -- both regional and nationwide. This new SEM, a cutting-edge research tool, which replaces a seriously outdated 1997-model SEM, will also serve as a training tool for students in earth and planetary sciences, biology and engineering. The SEM acquisition will support the education of graduate-level US science students through formal classes and hands-on training. Thus, the acquisition of a new SEM supports a broad spectrum of NSF funded research and education. The University of New Mexico is one of the most diverse major institutions of higher learning in our country. UNM is a majority-minority institution and federally classified Hispanic-serving institution with a large proportion of undergraduates from culturally diverse backgrounds. Accordingly, the EPS department has a long tradition of involving undergraduates in research activities and a significant proportion of these individuals are from underrepresented groups and minorities, in particular Hispanic and Native American.Acquisition of a new scanning electron microscope (SEM) with attached energy dispersive X-ray spectrometer (EDS) system and color cathodoluminescence (CL) detector will replace the present system at UNM. The instrument selected is a TESCAN Vega3 and an IXRF EDS. The Vega3 provides a large stage and chamber with additional ports for future added capabilities. High sensitivity backscattered electron imaging and color cathodoluminescence options will be included with the TESCAN, along with a LaB6 gun for improved resolution. The combination of analytical results of electron and X-ray excitation improves the overall accuracy of qualitative and quantitative analysis and enhances X-ray mapping capabilities. The rationale behind this acquisition is that we have a multi-faceted, active, productive, and dynamic research program at the University of New Mexico that will be greatly enhanced by this acquisition. We have an extensive track record for SEM and EPMA use and management, and a long history for allowing access to our labs to the scientific community.

新扫描电子显微镜（SEM）的获取将为新墨西哥大学（UNM）的地球与行星科学研究所（IOM）和地球与行星科学系（EPS）提供重大增强。 SEM将集成到UNM的多学科研究计划中，该计划为校园的科学界以及其他大学（包括地区和全国）的用户提供服务。这款新的SEM是一种尖端的研究工具，取代了严重的1997模型SEM，还将为地球和行星科学，生物学和工程学的学生提供培训工具。 SEM收购将通过正规课程和动手培训来支持研究生级科学专业学生的教育。因此，新SEM的获取支持广泛的NSF资助的研究和教育。新墨西哥大学是我国最多样化的高等教育机构之一。 UNM是多数占多数的机构，并且是联邦化的西班牙裔服务机构，具有来自文化多样的背景的大量本科生。 Accordingly, the EPS department has a long tradition of involving undergraduates in research activities and a significant proportion of these individuals are from underrepresented groups and minorities, in particular Hispanic and Native American.Acquisition of a new scanning electron microscope (SEM) with attached energy dispersive X-ray spectrometer (EDS) system and color cathodoluminescence (CL) detector will replace the present system at UNM.选择的仪器是Tescan Vega3和IXRF Eds。 VEGA3提供了一个大型舞台和室内，并提供了其他端口，以实现将来增加的功能。高灵敏度反向散射电子成像和颜色的阴极发光选项将与Tescan一起，以及LAB6枪，以改善分辨率。电子和X射线激发的分析结果的组合提高了定性和定量分析的总体准确性，并增强了X射线映射功能。这次收购背后的理由是，我们在新墨西哥大学拥有一个多方面的，活跃，富有成效和动态的研究计划，这将通过这次收购大大增强。我们在SEM和EPMA使用和管理方面拥有广泛的记录，以及允许进入我们的实验室进入科学界的悠久历史。
