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 This new SEM, a cutting-edge research tool, which replaces a seriously outdated 1997-model SEM, will also serve as a training tool for students in earth and planetary sciences, biology and engineering.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.

新的扫描电子显微镜（SEM）的购置将大大增强新墨西哥州大学（UNM）陨石研究所（IOM）和地球与行星科学系（EPS）的研究基础设施。SEM将被整合到UNM的多学科研究项目中，这些项目为校园内的科学界和来自其他大学的用户提供服务-包括区域和全国性的。这种新的扫描电镜是一种尖端的研究工具，它取代了严重过时的1997年型扫描电镜，也将作为地球和行星科学、生物学和工程学学生的培训工具。SEM的收购将通过正式课程和实践培训支持美国研究生水平的科学学生的教育。因此，收购一个新的SEM支持广泛的NSF资助的研究和教育。新墨西哥州大学是我国高等教育最多样化的主要机构之一。UNM是一个少数民族占多数的机构和联邦分类的西班牙裔服务机构，有很大比例的本科生来自不同的文化背景。因此，EPS部门有参与研究活动的本科生的悠久传统，这些人中有很大一部分是来自代表性不足的群体和少数民族，特别是西班牙裔和美洲原住民。一个新的扫描电子显微镜（SEM）与附加能量色散X射线光谱仪（EDS）系统和彩色阴极射线发光（CL）探测器的收购将取代UNM目前的系统。选择的仪器是TESCAN Vega 3和IXRF EDS。Vega 3提供了一个大型的舞台和腔室，并带有额外的端口，以满足未来增加的功能。高灵敏度背散射电子成像和彩色阴极射线发光选项将包括与TESCAN，沿着与LaB 6枪，以提高分辨率。电子和X射线激发的分析结果的结合提高了定性和定量分析的整体准确性，并增强了X射线绘图能力。此次收购背后的理由是，我们在新墨西哥州大学有一个多方面的，积极的，富有成效的和充满活力的研究计划，这将大大提高本次收购。我们在SEM和EPMA的使用和管理方面有着广泛的记录，并且在允许科学界访问我们的实验室方面有着悠久的历史。
