This award will permit the upgrading of existing equipment in the mineral physics laboratory at UC Santa Cruz. This equipment will not only provide a state-of-the-art training ground for a broad group of graduate and undergraduate students, but will also ensure adherence to high-level laser safety protocols. The mineral physics laboratory at UCSC has an extended history of training students for placement in academia and industry who have expertise in the high-pressure spectroscopy of Earth materials, and this upgrade will allow this training to continue with more user- and safety-friendly equipment. In addition to safety upgrades of the UCSC pressure-measurement system, a new Raman spectrometer will be acquired that will replace a marginally functional and obsolete 18-year old apparatus with an instrument that has higher spatial resolutions, vastly improved detection technology, and modern instrument-control and data-collection software. The issues addressed by the research enabled by this upgrade include: the water and carbon storage capacity of the deep Earth, and how exchange of water and carbon takes place between the deep Earth and the surface environment, with relevance to the formation of Earth?s oceans; the structure and physical properties of melts and fluids at high pressures, with implications for issues ranging from explosive volcanic events generated via subduction-related processes, to the possible presence of partially melted zones near Earth?s core-mantle boundary that may represent the ?roots? of deeply-derived volcanic upwellings. This apparatus will be deployed for non-high pressure materials-characterization as well, including probing fine-grained archeological samples, and fluid inclusion and paleontologic studies. In essence, it will also function as a tool for rapid and fine-scale mineral and fluid characterization that will yield insights into phenomena as diverse as the firing temperatures of ancient ceramics, the degree (and type) of fossilization produced in different geologic environments, and the compositions of ore-forming fluids trapped in mineral hosts.

该合同将允许升级加州大学圣克鲁斯矿物物理实验室的现有设备。该设备不仅将为广大研究生和本科生提供最先进的培训场地，还将确保遵守高水平的激光安全协议。UCSC的矿物物理实验室有着悠久的历史，培养学生在学术界和工业界的地位，他们在地球材料的高压光谱学方面具有专业知识，这次升级将使这种培训能够继续使用更多的用户和安全友好的设备。除了对UCSC的压力测量系统进行安全升级外，还将购置一台新的拉曼光谱仪，该光谱仪将取代一台功能有限且过时的18年旧仪器，该仪器具有更高的空间分辨率、大大改进的检测技术以及现代仪器控制和数据收集软件。此次升级所实现的研究所解决的问题包括：地球深部的水和碳储存能力，以及地球深部与地表环境之间的水和碳交换如何发生，与地球的形成有关？海洋;熔体和流体在高压下的结构和物理性质，对从通过俯冲相关过程产生的爆炸性火山事件到地球附近可能存在的部分熔融区等问题的影响？的核-幔边界可能代表？根？深源火山喷发该仪器也将用于非高压材料的表征，包括探测细粒考古样品，流体包裹体和古生物学研究。从本质上讲，它还将作为一种工具，用于快速和精细的矿物和流体表征，这将使人们深入了解古陶瓷的烧制温度，不同地质环境中产生的石化程度（和类型）以及矿物宿主中捕获的成矿流体的成分等多种现象。
