First demonstration of improved yield with reduced adiabat in inertial confinement fusion implosions on the National Ignition Facility Open
Laser-driven, indirect-drive inertial confinement fusion (ICF) experiments at the National Ignition Facility (NIF) recently achieved a target gain greater than one, where fusion energy output exceeds input laser energy [Abu-Shawareb et al.…

First indirectly driven liquid-DT filled double shell implosions at the National Ignition Facility Open
Double shell implosions aim to explore material mixing under fusion conditions in a volume burn geometry using high-Z metal pushers. High-Z pushers are more compressible than low-Z pushers enabling high stagnation pressure which reduces th…
