A new method of fabrication of the transparent solid hydrogen layer inside a microshell: the application to inertial confinement fusion

To form a smooth solid layer of the hydrogen isotope inside a microshell, a new approach is in progress where the basic principles of fabrication of fine dispersed compounds (solid solutions) with low doping are employed. This approach is shown to be applied experimentally using the H 2 /HD mixture with the HD concentration less than 1%. As a result, a transparent solid layer is formed inside a 500 µm glass shell. The layer keeps its transparency under cycling heating treatment from 5 to 16-20 K. The technique developed can be applied for fabrication of cryogenic targets used in the inertial confinement fusion.
