Frustraum 1100 campaign on the National Ignition Facility*

We report on capsule performance at 5% larger than current ignition-scale, driven by dual conical frustum-shaped hohlraums on the National Ignition Facility. The wall area of the frustraum is ~20% smaller than current cylindrical ignition hohlraums, which leads to an overall 12% more efficient hohlraum and higher radiation temperatures and stagnated ion temperatures for a given peak laser power. The first two layered implosions at this scale entered the burning plasma regime and exhibited an isobaric hotspot. We will also discuss proposed hohlraum geometry, drive profile and capsule thickness changes to increase time-dependent symmetry control and compression while maintaining overall drive efficiency.
