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 The original Kevex EDS (energy dispersive spectrometer) system likewise is seriously outdated and has no EDS imaging and mapping capability or light-element detection.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.***

通过主要研究仪器计划制造的0116660PingiorEthis Grant为升级UTEP 14岁的第一代Cameca SX-50 Electron Microprobe的操作系统提供了部分支持。我们将获取控制系统升级，以替换Cameca Microprobe上过时的基于DEC的PDP软件。 DEC系统不再由DEC或CAMECA支持；新开发的分析功能和成像功能尚不可用。原始的Kevex EDS（能量色散光谱仪）系统同样已过时，并且没有EDS成像和映射功能或光元素检测。我们将用具有完整成像和映射包，高计数率和光元素检测器窗口的系统替换。 UTEP的Electron Microprobe实验室是多用户和多学科的设施。它为来自我们校园的个人和团体提供研究，研究培训和教学职能，包括科学，工程，文科和健康科学学院成员。微探针实验室还协助El Paso-Juarez社区及以后的个人，企业，教育机构，政府机构和非政府组织。 这三个共同研究人员及其研究小组目前正在进行15个项目，这些项目将利用升级的设施。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，灌注，重金属的生物吸附，珊瑚的痕量元素，微螺旋藻数据量化，微孔数据定量，土壤中金属和Foram mg/ca Palemymermy的金属的概况。来自其他UTEP研究人员资助的项目的其他微型探针设备包括诸如色素，催化材料，考古，健康，土壤盐分，复合材料和异国合金等主题领域。 早期和持续接触研究是UTEP吸引和保留学生在科学和工程学中，尤其是代表性不足的少数群体的战略的重要组成部分。墨西哥裔美国人在UTEP约有2/3的学生团体。其中两个共同派是少数派成员，他们是特殊的榜样和密切的学生导师。仪器和实践实验室经验对于与通常决定其学术选择，成功和最终职业道路的学生建立“联系”很重要。***
