Investigations of Multi-ion and Kinetic Effects in High-Z doped laser-direct-drive Inertial Confinement Fusion implosions at OMEGA
POSTER
Abstract
Using a wealth of data acquired throughout various experimental campaigns executed from 2006 to 2008, the effect of multi-ion and kinetic physics during inertial confinement fusion
(ICF) implosions is quantified. Implosions were performed at the OMEGA 60 laser system, and utilized SiO 2 -hoppe-glass targets, filled with varying amounts of D 3 He and high-Z dopant gases.Using the combined data recorded by the Particle-temporal-diagnostic (PTD), Neutron-temporal diagnostic (NTD) and various time integrated proton spectrometers, time resolved D 2 and D 3 Heion temperatures and densities were inferred using parabolic density and temperature profiles.This modelling approach neglects multi-ion and kinetic mechanisms, such as ion-species separation and thermal decoupling that occur the during the shock-burn phase of an implosion. The resulting data, in the form of time-resolved ion temperature and density profiles, will be compared to ion-Fokker-Planck (iFP) simulations, which applies a kinetic and multi-ion treatment to ion species to quantify the effect of these mechanisms. For comparison, hydrodynamic simulations with the HYADES code are also conducted.
