Abstract
Abstract
The ignition is still unachieved in current schemes of inertial confinement fusion (ICF) despite significant efforts in this direction. The reason for it is unclear as the dynamics of target combine a lot of physical processes that are crucial for successful ignition. One possible limiting factor is known for a long time – hydrodynamic instabilities and mixing. Current work consider the effect of initial roughness on compression efficiency of ICF targets. The roughness is set on the ice–ablator boundary (outer ice interface). First, some analytical results on stability of accelerated perturbed interface are presented. Second, numerical simulations of ICF target show the influence of initial perturbations on hot–spot conditions and ice–ablator mixing.
