Approximate models for the ion-kinetic regime in inertial-confinement-fusion capsule implosions
Approximate models for the ion-kinetic regime in inertial-confinement-fusion capsule implosions
"Reduced" (i.e., simplified or approximate) ion-kinetic (RIK) models in radiation-hydrodynamic simulations permit a useful description of inertial-confinement-fusion (ICF) implosions where kinetic deviations from hydrodynamic behavior are important. For implosions in or near the kinetic regime (i.e., when ion mean free paths are comparable to the capsule size), simulations using a …
