| Outline of Final Research Achievements |
we improved the ultrasonic measurement system to obtain the elastic wave velocity under the condition of the lower mantle region, installing the high frequency waveform generator, the post amplifier and the semiconductor with a high-speed relay in the Kawai-type multi-anvil apparatus (SPEED-1500) at SPring-8.We successfully obtained the elastic wave velocities of the lower mantle mineral up to 50GPa and 1073K, corresponding to the lower mantle P-T conditions.
