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.

该奖项将资助升级一台二手的5光谱仪Cameca Instruments SX-100，该仪器由桑迪亚国家实验室退役，主要研究人员通过美国能源部的实验室设备捐赠计划从盈余中索赔。沿着其他重要的实验室组件，该合同将使该仪器进入全面运行状态，这将确保该区域设施保持开放，并准备好在未来使用。拟供资的设备包括一台新的可操作个人计算机、一套基于个人计算机的自动化软件包、相关固件、一台带帕尔贴冷却器的硅漂移固态能量色散X射线分析仪以及蒸发镀膜机的升级。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是经常使用的，有时是长期使用的。升级后的仪器将使研究的例子包括：石榴石，电气石和硅酸盐熔体之间的同位素化学H和F的实验研究，实验，以确定一个稳定的领域金伯利岩，富锆石榴石，和晶体成核和硅酸盐液体织物的研究。
