Ignition tuning for the National Ignition Campaign.

The overall goal of the indirect-drive inertial confinement fusion tuning campaigns is to maximize the probability of ignition by experimentally correcting for likely residual uncertainties in the implosion and hohlraum physics used in our radiation-hydrodynamic computational models, and by checking for and resolving unexpected shot-to-shot variability in performance. This has been started successfully using a variety of surrogate capsules that set key laser, hohlraum and capsule parameters to maximize ignition capsule implosion velocity, while minimizing fuel adiabat, core shape asymmetry and ablator-fuel mix.
