该奖项提供了50%的资金需要建设 五个特殊设计的高压反应容器， 温度设计、建造及营运 压力容器将在校长的指导下 地质行星科学部研究员 在加州理工学院。加州理工学院将提供 其余50%的资金将用于该项目。 所提出的设备结合了新颖的特征， 样品在实验期间被磁悬浮，并可 快速地移入和移出容器内的热区 而不释放压力。这些船只将广泛用于 各种旨在了解行为的项目 天然和合成模型火成岩中的挥发性组分 系统，包括：调查 水蒸气与硅酸盐熔体之间的氢同位素及其 与岩浆液体中水的物种形成的关系;研究 水和二氧化碳的溶解度和扩散 硅酸盐玻璃和熔体.碳分配的研究 蒸汽和硅酸盐熔体之间的同位素。

This award provides 50% of the funding needed to construct five special design reaction vessels for use at high pressure and temperature. The design, construction and operation of the pressure vessels will be under the direction of the Principal Investigator in the Division of Geological & Planetary Sciences at the California Institute of Technology. Caltech will provide the remaining 50% funding necessary for the project. The proposed apparatus incorporates a novel feature whereby the sample is magnetically levitated during an experiment and can be rapidly moved into and out of the hot zone within the vessel without release of pressure. The vessels will be used in a wide variety of projects aimed at understanding the behavior of volatile components in natural and synthetic model igneous systems, including: investigations of the partitioning of hydrogen isotopes between vapor and silicate melts and its relation to the speciation of water in magmatic liquids; studies of the solubility and diffusion of water and carbon dioxide in silicate glasses and melts; study of the partitioning of carbon isotopes between vapor and silicate melts.
