Results of structured load implosion experiments and its comparison with simulation

Abstract

Loads with a structured density profile (such as double gas puffs or uniform fill loads) can be an alternative to conventional thin shells when implosions from large initial diameters with long implosion times are desired. It was shown in the experiments that radiative performance of thin shell decreases significantly as the initial load radius exceeds 2 cm. Structured loads are expected to be more stable due to the mechanism of snow-plow stabilization. The experiments with structured load were carried out on GIT-12 generator (2.5 MA, 2.4 MJ). Implosions of structured load were simulated with the help of quasi two-dimensional model. The experimental results and their comparison with the results of simulations are presented.
