| Target pellets used in inertial confinement fusion, based on Deuterium-Tritium fuel, follow a complex manufacturing process of permeation at temperatures near the triple point [1]. Details of such process seem to induce the nucleation of anisotropic crystal, structures organized in layers with pseudo nanocrystalline properties. This spatial order posses a serious problem since may affect the efficiency of Inertial Fusion implosion [2]. We report theoretical studies on the solid molecular hydrogen and the methodology to applied in hydrogen isotopes and their mixtures, looking for metastable structures and their characteristics, as reported in previous experimental work [3]. Working in conditions close to the triple point is a difficult experimental task. On the contrary, our methodology, based in a quantum molecular dynamics approach, is able to provide a good description of the properties and the spatial arrangement exhibited by the hydrogen isotopes under extreme conditions. A nice achievement of our work presented here, is the construct the theoretical phase diagram for hydrogen (H), deuterium (D) and tritium (T), and mixtures there of, in particular DT mixture, at low temperatures and low pressures | |
