Abstract
High fuel compression has been successfully achieved through implosions utilizing high-density carbon ablators at the National Ignition Facility. The new drive and ablator profile have resulted in a significant improvement in the measured down-scattered neutron fraction, which is a metric of compression, compared to previously established designs. This enhancement is attributed to increased stability and reduced adiabat.
