Abstract

The experiments to study the indirect drive targets' dynamics in a highly symmetrical X-radiation field were performed on the ISKRA-5 facility. This paper covered the results of experiments with the targets in the form of a Cu spherical hohlraum, the internal surface of which is coated with Au, with six holes for laser radiation input. In the center of the aforementioned hohlraum, a glass capsule filled with D–T gas was placed. In several experiments, the central capsule was coated with an ablator made of plastic with a different thickness. This allowed us to perform a series of experiments in which the different compression degree of D–T fuel was achieved. The analyses of experimental results revealed good agreement between the latter and the spherically symmetrical hydrodynamic calculations.
