Title: Implosion in water medium and its possible application for the inertial confinement fusion target ignition

Abstract

A numerical and self-similar analysis of the generation of implosion in water medium in cylindrical and spherical geometries is presented. The following interaction of the implosion wave with a deuterium-tritium mixture target is analyzed. It was found that the established converging cumulative water flow is self-similar, in spite of the complexity of the implied equations of state. Results of an idealized model indicate that, using a spherical geometry setup with 7.5 mm external radius of the water layer and {approx}35 kJ total deposited energy, a {approx}1.5x10{sup 14} neutron yield during {approx}1.5 ns time can be achieved. The obtained results suggest that ignition of deuterium-tritium target by implosion in water medium can be considered as a promising method for inertial confinement fusion.
