This project will develop new equipment capable of generating precise, high-frequency (500 MHz) ultrasonic equation of state data at hydrostatic pressures up to 40 kilobars and temperatures up to 1500K. The data are needed to interpret seismic velocity data in terms of Earth models of density and mineral phase distribution with depth. The apparatus will be designed to accommodate solid samples of mantle materials up to 5 mm in diameter. The system will enable the measurement of elastic constants and their pressure and temperature derivatives.

该项目将开发新的设备，能够在高达40千巴的静水压力和高达1500K的温度下产生精确的高频（500 MHz）超声状态方程数据。这些数据需要用密度和矿物相随深度分布的地球模型来解释地震速度数据。该仪器将被设计用于容纳直径达5毫米的地幔材料的固体样品。该系统将能够测量弹性常数及其压力和温度导数。
