This grant provides partial support for upgrading the Impulsive Stimulated Scattering (ISS) Laboratory at the University of Washington. The ISS Laboratory has been in nearly continuous operation for over eight years. In part, upgrade work is needed because critical components (lasers, mirrors, optical devices and mounts, electronics, and computer systems) are nearing reasonable life expectancies. More importantly however, new technology, now availale, will extend the capabilities of the laboratory to higher temperatures, and to the study of more difficult and substantially smaller samples. Accurately characterized physical properties of minerals and fluids are prerequisite for any effort to understand processes within Earth. Impulsive Stimulated Scattering offers a versatile approach to the measurement in a single experiment of the elastic moduli, the equation of state, the thermal diffusivity, the viscosity, and the dynamics of molecular reorientation in fluids and in very small crystals. ISS has proven to be well adapted both to observations at very high temperatures and to the requirements of the diamond-anvil cell and to those of more conventional high-pressure systems. The ISS lab is operated and utilized by an interdisciplinary (Mineral Physics) group including, Michael Brown (Geophysics), Leon Slutsky (Chemistry), and Evan Abeamson (Chemistry) with collaborations in the Geological Sciences (Mark Ghiorso) and Physics (Robert Ingalls) Departments. Undergraduate and graduate students from Geophysics, Geological Sciences, Chemistry, and Physics also participated in research in the ISS lab.***

这笔赠款为华盛顿大学的脉冲受激散射（ISS）实验室的升级提供部分支持。 国际空间站实验室已连续运行了八年多。 在某种程度上，升级工作是必要的，因为关键部件（激光器，镜子，光学设备和安装，电子和计算机系统）接近合理的预期寿命。 然而，更重要的是，现在可用的新技术将使实验室的能力扩展到更高的温度，并研究更困难和更小的样品。 准确表征矿物和流体的物理性质是理解地球内部过程的先决条件。 脉冲受激散射提供了一种多功能的方法来测量在一个单一的实验中的弹性模量，状态方程，热扩散率，粘度，以及在流体和非常小的晶体中的分子重新取向的动力学。 国际空间站已被证明非常适合在极高温度下进行观测，也非常适合金刚石压砧室的要求和更传统的高压系统的要求。 国际空间站实验室由一个跨学科（矿物物理学）小组运营和使用，包括Michael Brown（地球物理学），Leon Slutsky（化学）和Evan Abeamson（化学），并与地质科学（Mark Ghiorso）和物理（Robert Ingalls）部门合作。 地球物理学、地质科学、化学和物理学的本科生和研究生也参加了国际空间站实验室的研究。
