9405579 Heinz The PI will perform laser heating and Brillouin scattering experiments on a range of materials. He will revisit the melting behavior of perovskite and Fe using his new thermal analysis technique to provide better constraints on the thermal structure of the deep Earth. He will also determine elastic velocities in several silicates, oxides and alkali halides in polycrystalline form. These experiments, coupled with seismic observations, will permit a better understanding of the deep structure and composition of the Earth. ****

小行星9405579海因茨 PI将在一系列材料上进行激光加热和布里渊散射实验。 他将使用新的热分析技术重新审视钙钛矿和Fe的熔融行为，以更好地约束地球深部的热结构。 他还将测定几种硅酸盐、氧化物和碱金属卤化物多晶形式的弹性速度。 这些实验，加上地震观测，将使人们能够更好地了解地球的深层结构和组成。 ****
