The High Energy Density Physics (HEDP) group at the MIT Plasma Science and Fusion Center conducts experiments at the OMEGA laser facility to study prevalence and impact of multi-ion and kinetic effects in inertial confinement fusion (ICF) and nuclear astrophysics-relevant implosion experiments. LANL's Vlasov-Fokker-Planck iFP code has emerged as an extremely useful tool for designing and interpreting results from these experiments. In this talk, several examples of this work are highlighted. This includes discussion of results from studies of interdiffusion of shell and fuel material, kinetic mix, and multi-ion effects when transitioning from a kinetic to hydrodynamic-like regime in shock driven implosions. Results from a study with mid-Z N2 gas added to standard D2 gas in the capsule fill, emphasizing the importance of interspecies dynamics including equilibration and diffusion, are also shown. Finally, preliminary data and simulations from a new effort aiming to directly measure non-Maxwellian ion velocity distributions in ICF-relevant plasmas are presented. Host: William T. Taitano (T-5) |
