Phys. Rev. Lett. 88, 215004 (2002) [4 pages]Double Z-Pinch Hohlraum Drive with Excellent Temperature Balance for Symmetric Inertial Confinement Fusion Capsule ImplosionsReceived 28 January 2002; published 13 May 2002 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 〈Δr〉/r≤30% are possible on the Z accelerator and may meet radiation symmetry requirements for scaling to fusion yields of >200MJ. © 2002 The American Physical Society URL:
