0116660PingitoreThis grant, made through Major Research Instrumentation Program, provides partial support of the costs for upgrading the operating system of UTEP's 14-year-old, first generation Cameca SX-50 electron microprobe. We will acquire a control system upgrade to replace the antiquated DEC PDP-based software on our Cameca microprobe. The DEC system is no longer supported by DEC or Cameca; newly developed analytical and imaging capabilities have not been available to us. The original Kevex EDS (energy dispersive spectrometer) system likewise is seriously outdated and has no EDS imaging and mapping capability or light-element detection. We will replace this with a system featuring a full imaging and mapping package, high counting rate, and light-element detector window. UTEP's electron microprobe laboratory is a multi-user and multi-disciplinary facility. It serves research, research training and instructional functions for individuals and groups from across our campus, including members of the Colleges of Science, Engineering, Liberal Arts, and Health Sciences. The microprobe laboratory also assists individuals, businesses, educational institutions, government agencies, and non-governmental organizations in the El Paso-Juarez community and beyond. The three co-investigators and their research groups have 15 projects, currently underway, which will make use of the upgraded facility. These research projects include the following topics: tectonics, metamorphic reactions, phytoremediation, environmental bio-sensors, desert varnish, particulate matter air pollution, plutonism, biosorption of heavy metals, trace elements in corals, microprobe data quantification, speciation of metals in soil, and foram Mg/Ca paleothermometry. Additional microprobe equipment use on funded projects from other UTEP researchers includes such topic areas as pigments, catalytic materials, archaeology, health, soil salination, composites, and exotic alloys. Early and continued exposure to research is an essential part of UTEP's strategy to attract and retain students in science and engineering, particularly under-represented minorities. Mexican-Americans comprise approximately 2/3 of the student body at UTEP. Two of the Co-PIs are minority members, who serve as special role models and close student mentors. Instrumentation and hands-on laboratory experience are important to establish the "connection" with students that often determines theiracademic choices, success, and ultimate career paths.***

0116660 Pingitore这笔赠款通过重大研究仪器计划提供部分支持，用于升级UTEP已有14年历史的第一代Cameca SX-50电子微探针的操作系统。我们将对控制系统进行升级，以替换我们Cameca微探头上过时的基于DEC PDP的软件。DEC或Cameca不再支持DEC系统；我们无法获得新开发的分析和成像功能。原来的Kevin ex EDS(能量色散光谱仪)系统同样严重过时，没有EDS成像和测绘能力或轻元素探测。我们将用一个具有完整的成像和测绘包、高计数率和轻元素探测器窗口的系统来取代它。UTEP的电子探针实验室是一个多用户、多学科的设施。它为来自我们校园的个人和团体提供研究、研究培训和指导功能，包括理学院、工程院、文学院和健康科学学院的成员。微探头实验室还协助埃尔帕索-华雷斯社区内外的个人、企业、教育机构、政府机构和非政府组织。三名联合调查员及其研究小组目前有15个项目正在进行中，这些项目将利用升级后的设施。这些研究项目包括以下主题：构造、变质反应、植物修复、环境生物传感器、沙漠清漆、颗粒物空气污染、深成作用、重金属的生物吸附、珊瑚中的微量元素、微探针数据量化、土壤中金属的形态和有孔镁钙古温度法。其他UTEP研究人员资助的项目使用的其他微探头设备包括颜料、催化材料、考古、健康、土壤盐化、复合材料和外来合金等主题领域。早期和持续地接触研究是UTEP吸引和留住理工科学生，特别是代表性不足的少数族裔的战略的重要组成部分。墨西哥裔美国人约占UTEP学生总数的三分之二。其中两名合作伙伴是少数族裔成员，他们是特殊的榜样和亲密的学生导师。仪器设备和实验室实践经验对于建立与学生的“联系”非常重要，这往往决定着他们的学术选择、成功和最终的职业道路。
