Development of an Interferometer Dilatometer to Measure Thermal Expansion Above 1200K

9506650安德森 该奖项提供了部分资金用于开发一种用于测量晶体热膨胀至1800 K温度的膨胀计。该仪器的设计基于激光光学干涉测量的应用，在首席研究员实验室建造的原型已经证明了高达1000K的能力。改进设计以提高温度性能十分重要，因为该仪器的主要应用将是确定在地壳和上地幔高温条件下稳定的矿物相的热膨胀系数。 ***

9506650 Anderson This award provides partial funding for the development of a dilatometer to measure the thermal expansion of crystals up to temperatures of 1800K. The instrument design is based on the application of laser optical interferometry, and a prototype built in the principal investigator's laboratory has demonstrated capabilities up to 1000K. Upgrading the design for performance at higher temperatures is important because the main applications of the instrument will be to characterize the thermal expansion coefficients of mineral phases stable under the high-temperature conditions of the Earth's crust and upper mantle. ***
