Development of loading system for liquid hydrogen into diamond-anvil cells under low temperature.
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.
