Abstract

A double $Z$ pinch driving a cylindrical secondary hohlraum from each end has been developed which can indirectly drive intertial confinement fusion capsule implosions with time-averaged radiation fields uniform to $2 % - 4 %$ . 2D time-dependent view factor and 2D radiation hydrodynamic simulations using the measured primary hohlraum temperatures show that capsule convergence ratios of at least 10 with average distortions from sphericity of $〈 Δ r 〉 / r \leq 30 %$ are possible on the $Z$ accelerator and may meet radiation symmetry requirements for scaling to fusion yields of $> 200 MJ$ .
