Behavior of Coulomb-hydrodynamic explosion of deuterium clusters

摘要

Considering the Coulomb-hydrodynamic explosion induced by the interaction of a deuterium cluster target with ultra-intensity femtosecond laser, the mechanism which generates energetic deuterium nuclei for the fusion has been analyzed. The formulas for expansions of the deuterium ion cluster, which are driven by the Coulomb-hydrodynamic explosion, are proposed. Hence the kinetic energies of deuterium nuclei and the expansion time of deuterium ion cluster have been estimated.
