MRI: Proposal to Purchase a ESEM with CL, STEM, and EDX, at Idaho State University

爱达荷州州立大学创建了考古、材料和应用光谱学中心（卡马斯），这是一个致力于整合社会、自然和物理分析科学的跨学科研究机构。该中心成功的关键，以及爱达荷州州立大学的一个重要需求，是获得环境扫描电子显微镜（SEM）进行研究和学生培训。 该合同将允许采购具有扫描透射显微镜、能量色散X射线光谱分析能力、波长色散X射线光谱分析能力和阴极发光成像能力（SEM/STEM/EDS/WDS/CL）的扫描电子显微镜。该扫描电镜将成为考古学、地质学、生物学、材料科学及相关领域的重要研究工具。ISU是一个不断发展的研究机构，目前在现代扫描电子显微镜的研究或教育机会有限或没有。对元素分析，材料分析，结构分析以及目前对考古学，地球科学，生态学和化学等一系列学科的研究进展至关重要的分析领域感兴趣的研究人员和学生现在将能够在爱达荷州州立大学进行先进的SEM研究。无损分析技术对现代考古学和物理科学的发展至关重要。扫描电镜在整个人工制品分析、纳米技术、古生物学和其他领域的能力将使ISU在科学上具有竞争力。 内置的EDS和WDS分析系统，加上阴极发光（CL），将使我们能够进行结构变化和定量元素分析的成像，以及使用EDS/WDS和背散射电子成像（BSE）进行地质和考古材料的微观结构形态研究。CL成像和分析功能提供了急需的绘制化学和相分带的能力，这对于构建地质矿物历史和考古陶瓷中矿物回火的成分来源至关重要。扫描电镜的成像能力将用于生物微体化石的分类鉴定，如花粉，植硅石，硅藻和苔藓虫，将成为古生物学家，地质生物学家和考古学家为该项目做出贡献的工作的核心，并将开辟化学研究和分析的新领域。

Idaho State University created the Center for Archaeology, Materials, and Applied Spectroscopy (CAMAS), an interdisciplinary research facility dedicated to the integration of social, natural, and physical analytical sciences. Critical to the success of this center, and an important need for Idaho State University, is access to an environmental scanning electron microscope (SEM) for research and student training. This award will allow the acquisition of a scanning electron microscope with scanning transmission microscopy, energy dispersive x-ray spectrometry capability, wavelength dispersive X-ray spectroscopy capability, and cathodoluminescence imaging capabilities (SEM/STEM/EDS/WDS/CL). The proposed SEM will be a significant research tool in archaeology, geology, biology, materials science, and related fields. ISU is a growing research institution that currently has limited or no opportunities for research or education in modern scanning electron microscopy. Researchers and students interested in elemental analysis, materials analysis, structural analysis, and the gamut of analyses currently critical to the advancement of research in a suite of disciplines including archaeology, the earth sciences, ecology, and chemistry will now be able to conduct advanced SEM research at Idaho State University. Non-destructive analysis techniques are critical to the development of modern archaeological and physical sciences. The capabilities of SEM for whole artifact analysis, nano-technology, paleontology, and other areas will make ISU scientifically competitive. The built in EDS and WDS analysis systems, with the addition of Cathodolumenescence (CL), will allow us to conduct imaging of structural variation and quantitative elemental analysis, as well as micro-structural morphological studies of geological and archaeological materials using EDS/WDS and backscattered electron imaging (BSE). CL imaging and analysis functionality provides the much-needed ability to map chemical and phase zonation critical for constructing geological mineral histories and for compositional sourcing of mineral tempers in archaeological ceramics. The imaging capabilities of the SEM will be used for taxonomic identification of biological microfossils such as pollens, phytoliths, diatoms and bryozoans, will be central to the work of the paleontologists, geobiologists and archaeologists contributing to the project, and will open up new fields of chemical research and analysis.
