Studies of multi-ion and kinetic effects in shock-driven and ablatively-driven implosions at OMEGA

POSTER

Abstract

Two experiments at OMEGA are discussed, focusing on the impact of multi-ion and kinetic effects on the shock-convergence and compression phases of an Inertial Confinement Fusion (ICF) implosion. Such effects are known to significantly impact the final yield of an ICF implosion. The first experiment involved shock-driven implosions with varying Knudsen numbers from fully kinetic to hydro-like behavior. The second experiment involved compressively-driven implosions with varying combinations of shell thickness and laser drive used to produce different shock strengths and to probe conditions when the implosion transitions from the shock to compression phase. In both cases, data from the Particle X-ray Temporal Diagnostic (PXTD) and the Neutron Temporal Diagnostic (NTD) provided information about particle emission histories for DD-neutron, DT-neutron and D3He-proton reactions, referenced against spectral information from CR-39-based diagnostics and time-of-flight diagnostics. Comparison of the time-resolved data from these experiments with theory and simulation informed an analysis of the role of kinetic and multi-ion effects in ICF implosions.
