HybridB design and comparison to data

ORAL

Abstract

The maximal performance of Inertial Confinement Fusion (ICF) implosions is governed by four key parameters, implosion velocity, adiabat, inflight ablation pressure and capsule size [1]. Experiments on the NIF have roughly bracketed the values of implosion velocity, adiabat and ablation pressure for current systems. Using these parameters, “hybrid” campaigns now aim to optimize the capsule size that produces overall optimal performance in a cylindrical hohlraums at full NIF power and energy. An experimental database was used to inform hohlraum design choices [2] to preserve symmetry. The first of these campaigns, “HybridB”, used a high density carbon (HDC or diamond) ablator and combined features of current platforms and new aspects to increase capsule scale by 5-15%. Results show sufficient inner beam propagation and a path to further increasing the capsule scale. This talk outlines the HybridB design and comparison to experimental data.
