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

该合同将用于升级由桑迪亚国家实验室退役的二手5分光计Cameca Instruments SX-100，主要研究人员通过能源部的实验室设备捐赠计划从盈余中获得该设备。与其他必要的实验室部件一起，该奖项将使该仪器进入全面运行状态，这将确保这一地区性设施保持开放，并为未来的使用做好准备。将资助的设备包括一台新的操作个人计算机(PC)、一台基于PC的自动化组件、相关固件、一台带有珀尔蒂埃冷却器的硅漂移固态能量色散X射线分析仪，以及对蒸发镀膜机的升级。该设施的经常用户大多来自地质学，但人类学、其他自然科学和工程学的教职员工和学生是经常使用该设施的人，有时甚至很长时间。升级后的仪器将支持的研究实例包括：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，为沸石和富锆石确定稳定场的实验，以及硅酸盐液体中晶体成核和组构的研究。

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.
