Acquisition of an Energy Dispersive X-ray Spectrometer

这种能够检测轻元素的能量色散x射线光谱仪和一个带有能够进行定量薄膜化学分析的软件的计算机工作站将使密苏里大学罗拉分校的教师和研究生能够进行定量薄膜微化学分析。这种光谱仪将安装在现有的透射电子显微镜上。还要求配备电视摄像机、冷台、热台和扫描传输装置等辅助设备。目前正在进行的研究包括：1)不能通过标准热工艺生产的新型电沉积形状记忆合金，2)具有独特电学和光学特性的陶瓷超晶格，以及3)具有重要技术意义的新型稀土磁性材料。要求一台能检测轻元素的能量色散x射线光谱仪和一台能进行定量薄膜化学分析的计算机工作站。这种光谱仪将安装在现有的透射电子显微镜上。目前的研究主要集中在电沉积形状记忆合金、陶瓷超晶格、新型稀土磁性材料等方面。材料处理是每个项目的中心主题，分析装备的透射电子显微镜对于这些令人兴奋的新材料的表征至关重要。

This energy dispersive X-ray spectrometer capable of detecting light elements and a computer work station with software capable of performing quantitative thin film chemical analysis will enable faculty and graduate students to perform quantitative thin film microchemical analysis at the University of Missouri-Rolla. This spectrometer is to be installed on an existing transmission electron microscope. Ancillary equipment that includes a TV camera, cold stage, hot stage and scanning transmission device are also requested. Current research is being performed on synthesis of: 1) novel electrodeposited shape memory alloys that cannot be produced by the standard thermal process, 2) ceramic superlattices that have unique electrical and optical properties, and 3) new rare earth magnetic materials that are technologically important. %%% An energy dispersive X-ray spectrometer capable of detecting light elements and a computer work station with software capable of performing quantitative thin film chemical analysis is requested.
