0824714MoecherThis proposal seeks funding to upgrade the existing Applied Research Laboratories SEMQ electron microprobe at the University of Kentucky. Requested upgrades include replacing components of the beam-forming and imaging electronics, purchasing components to improve the imaging capabilities and enhance qualitative and quantitative analyses, and upgrading computer software and hardware. Electronics upgrades are sought due to the instrument?s age and considerable recent down-time. Refurbished components will be sourced from the manufacturer. To improve imaging capabilities, a cathodoluminescence (CL) detector is requested along with an OV98 multilayer crystal for wavelength dispersive analysis. A new EDS imaging system with Peltier cooling will provide analytical flexibility for the new detectors. New software/hardware will consist of upgrades to Probe for Windows to Enterprise edition and a new computer to hold DAQ boards and run software. The instrumentation upgrade will be employed for on-going NSF EAR-funded and other research projects. Major objectives include: 1) zircon and monazite geochronology - CL imaging will be a key component for elucidating compositional information, while automated stage positioned ED spectral analysis will facilitate geochronologic reconstructions, 2) garnet and other silicate zoning analysis using visualization capabilities - thermobarometry, geochronology and structural analysis will be assessed using X-ray mapping, 3) decompression microstructures - retrograde eclogites, high-pressure granulites, and their inclusions will be used to better understand the burial and exhumation history of Paleozoic collision orogenesis, 4) Paleoseismicity and petrogenesis - pseudotachylyte (PST) will be assayed in order to assess formation temperatures and fluid states, 5) coal and shale geochemistry and mineralogy - organic and inorganic components will be evalued using WDS and EDS in coals and black shales, and 6) SE, BSE and EDS analysis of archeological artifacts in order to characterize their origins and uses. The current probe has four wavelength dispersive spectrometers, a BSE, and an EDS. The new CL detector and crystal will be incorporated into the existing instrument configuration and supported by the proposed software upgrade. The instrument is housed in a modern, capable facility with ample services. Departmental funds are used for gases and liquid nitrogen. Instrument service is performed by the PI and graduate students. A service contract is funded by the University. Usage fees are collected when volunteered. ***

0824714MOECHERTHIS提案寻求资金来升级肯塔基大学现有的应用研究实验室Semq Electron Microprobe。要求的升级包括更换梁形成和成像电子的组件，购买组件以提高成像功能并增强定性和定量分析，以及升级计算机软​​件和硬件。由于工具的年龄​​和最近的停机时间，要寻求电子升级。翻新的组件将来自制造商。为了提高成像能力，请求使用阴极发光（CL）检测器以及OV98多层晶体进行波长分析。带有Peltier冷却的新EDS成像系统将为新探测器提供分析灵活性。新的软件/硬件将包括升级以探测Windows到Enterprise Edition和一台新计算机，以持有DAQ板和运行软件。仪器升级将用于正在进行的NSF耳放和其他研究项目中。 Major objectives include: 1) zircon and monazite geochronology - CL imaging will be a key component for elucidating compositional information, while automated stage positioned ED spectral analysis will facilitate geochronologic reconstructions, 2) garnet and other silicate zoning analysis using visualization capabilities - thermobarometry, geochronology and structural analysis will be assessed using X-ray mapping, 3) decompression microstructures - retrograde eclogites, high-pressure granulites, and their inclusions will be used to better understand the burial and exhumation history of Paleozoic collision orogenesis, 4) Paleoseismicity and petrogenesis - pseudotachylyte (PST) will be assayed in order to assess formation temperatures and fluid states, 5) coal and shale geochemistry and mineralogy - organic and inorganic components will be使用WDS和ED在煤和黑色页岩中进行评估，以及6）SE，BSE和EDS分析考古文物的分析，以表征其起源和用途。当前的探针具有四个波长色散光谱仪，一个BSE和一个EDS。新的CL检测器和晶体将被合并到现有的仪器配置中，并由建议的软件升级支持。该仪器位于现代，能力的设施中，并提供充足的服务。部门资金用于气体和液氮。仪器服务由PI和研究生进行。服务合同由大学资助。自愿时会收取使用费。 ***
