Acquisition and Implementation of a Cameca SX-100 Electron Microprobe Laboratory, University of Oklahoma

该合同将为桑迪亚国家实验室退役的Cameca仪器SX-100二手5光谱仪的升级提供资金，主要研究人员通过美国能源部的实验室设备捐赠计划从剩余设备中索赔。与其他重要的实验室组件一起，该合同将使该仪器处于全面运行状态，这将确保该区域设施保持开放，并为未来的使用做好准备。资助的设备包括一台新的可操作个人计算机（PC）、一个基于PC的自动化软件包、相关固件、一个带珀尔捷冷却器的硅漂移固态能量色散x射线分析仪，以及对蒸发涂层机的升级。该设施的常规用户主要来自地质学，但人类学、其他自然科学和工程学的教职员工和学生也经常使用，有时使用时间很长。升级后的仪器可用于研究的实例包括：石榴石、电气石和硅酸盐熔体中同位素化学H和F的实验研究，确定富锆石榴石金泽石稳定性场的实验，以及硅酸盐液体中晶体成核和结构的研究。

This award will fund the upgrade of a used, 5-spectrometer Cameca Instruments SX-100 that was decommissioned by Sandia National Laboratory and which the principal investigators claimed from surplus through DOE's Laboratory Equipment Donation Program. Along with other essential lab components, this award will bring this instrument to fully operational status, which will ensure that this regional facility remains open and ready for use well into the future. Equipment to be funded includes a new operational personal computer (PC), a PC-based automation package, associated firmware, a silicon-drifted solid-state energy-dispersive x-ray analyzer with Peltier cooler, and upgrades to the evaporative coater. Regular users of the facility come mostly from geology, but faculty members and students of anthropology, other natural sciences, and engineering are frequent and sometimes lengthy users. Examples of research to be enabled by the upgraded instrument include: experimental studies of isotope chemistry H and F among garnet, tourmaline, and silicate melts, experiments to define a stability field for kimzeyite, a Zr-rich garnet, and studies of crystal nucleation and fabric in silicate liquids.
