Development of a Piston Cylinder Apparatus

该奖项为用于高压和高温（高达50千巴和2000开尔文）下材料研究的活塞缸装置的组装提供支持。资金还用于将一台2000吨的压力机从俄亥俄州运送到马萨诸塞州的剑桥，在那里，首席研究员将把它纳入一个实验性高压系统。这台印刷机是由位于俄亥俄州沃辛顿的通用电气超磨料部捐赠给麻省理工学院的。升级后的高压系统将用于实验，其目的是确定与地球下地壳和上地幔岩浆形成有关的固熔化学反应，并确定这些反应的温度和压力条件。

This award provides support for the assembly of what is known as a piston-cylinder apparatus used for the study of materials at high pressures and temperatures (up to 50 kilobars and 2000 degrees Kelvin). Funds are also provided for the shipping of a 2000-ton press from Ohio to Cambridge, Massachusetts where it will be incorporated by the Principal Investigator into an experimental high-pressure system. The press is being donated to the Massachusetts Institute of Technology by the General Electric Superabrasive Division in Worthington, Ohio. The upgraded high-pressure systems will be used in experiments whose purpose is to define solid-melt chemical reactions that are relevant to the formation of magmas in the earth's lower crust and upper mantle, and to determine the temperature and pressure conditions of these reactions.
