Abstract

Radiation-driven, layered deuterium-tritium plastic capsule implosions were carried out using a new, 3-shock "adiabat-shaped" drive on the National Ignition Facility. The purpose of adiabat shaping is to use a stronger first shock, reducing hydrodynamic instability growth in the ablator. The shock can decay before reaching the deuterium-tritium fuel leaving it on a low adiabat and allowing higher fuel compression. The fuel areal density was improved by ∼25% with this new drive compared to similar "high-foot" implosions, while neutron yield was improved by more than 4 times, compared to "low-foot" implosions driven at the same compression and implosion velocity.
