Abstract

A loading system for hydrogen gas into the diamond-anvil cell has been developed. The loading of hydrogen gas is performed under low temperature by using liquid helium as a cooling medium. Also, a compression apparatus has been developed to load gaseous materials into various diamond-anvil cells. The present loading system and compression apparatus have been used successfully to form hydrogen hydrate. The present loading system can also be used to load other gaseous materials as a pressure medium.

摘要

已开发出一种用于将氢气加载到金刚石对顶砧室中的加载系统。通过使用液氦作为冷却介质在低温下进行氢气加载。此外，还开发了一种压缩装置，用于将气态材料加载到各种金刚石对顶砧室中。目前的加载系统和压缩装置已成功用于形成水合氢。目前的加载系统还可用于加载其他气态材料作为压力介质。
