Implosion of a two-layer shell driven by a shaped pressure pulse
An analytical model for the implosion of a two-layer spherical shell target driven by a two-step pressure pulse is developed. The process of formation of the central spark is approximately described and the effect of the prepulse on the final stage of fuel and pusher is studied. The size of the cent...
