0957137ManghnaniThis grant supports upgrade and new capabilities at the University of Hawaii Mineral Physics Laboratory with the Hawaii Institute of Geophysics and Planetology. New equipment to be acquired incrementally over the next three years will include: 1) a solid state laser that would be employed for Raman and Brillouin spectroscopic measurements of the elastic and structural properties of hydrous and anhydrous silicate glasses and melts under high temperature and pressure conditions in the laser heated diamond anvil cell (DAC); 2) electronics necessary for ultrasonic measurements of the compressibility of silicate melts in the large volume press; 3) microscopes and computer controlled translation stage for diamond anvil sample loading and micro-Raman scattering experiments; 4) an vibration isolated optical table to support new Raman and Brillouin spectroscopic capabilities; 5) a new power supply for an existing Raman system; 6) equipment to support development of a new spectroradiometric system for measuring temperature in situ in the laser heated diamond anvil cell; and 7) a new control system for an existing Brillouin spectrometer. The lab upgrade will allow for the collection of new observations of silicate melt elasticity at pressure and the effects of water on melt structure and compressibility. The lab upgrades will support student and postdoctoral research training in materials characterization methods with implications for supporting the next generation geoscience workforce and the development of synthetic materials for societal and military applications.***

这项拨款支持夏威夷大学矿物物理实验室与夏威夷地球物理和行星学研究所的升级和新能力。未来三年将逐步获得的新设备将包括：1)固体激光器，用于在激光加热的金刚石砧池（DAC）高温高压条件下对含水和无水硅酸盐玻璃的弹性和结构特性进行拉曼和布里渊光谱测量；2)大容积压机中硅酸盐熔体可压缩性超声测量所需的电子学；3)用于金刚石砧样加载和微拉曼散射实验的显微镜和计算机控制平移台；4)一个隔振光学工作台，支持新的拉曼和布里渊光谱功能；5)现有拉曼系统的新电源；6)用于支持新型光谱辐射测量系统开发的设备，该系统用于在激光加热的金刚石砧槽中原位测量温度；7)现有布里渊光谱仪的新控制系统。实验室的升级将允许收集压力下硅酸盐熔体弹性和水对熔体结构和可压缩性影响的新观测结果。实验室升级将支持学生和博士后在材料表征方法方面的研究培训，这对支持下一代地球科学劳动力和用于社会和军事应用的合成材料的开发具有重要意义
