Hohlraum-driven ignitionlike double-shell implosions on the omega laser facility

High-convergence ignitionlike double-shell implosion experiments have been performed on the Omega laser facility using cylindrical gold hohlraums with 40 drive beams. Repeatable, dominant primary (2.45 MeV) neutron production from the mix-susceptible compressional phase of a double-shell implosion,...

Zusammenfassung:High-convergence ignitionlike double-shell implosion experiments have been performed on the Omega laser facility using cylindrical gold hohlraums with 40 drive beams. Repeatable, dominant primary (2.45 MeV) neutron production from the mix-susceptible compressional phase of a double-shell implosion, using fall-line design optimization and exacting fabrication standards, is experimentally inferred from time-resolved core x-ray imaging. Effective control of fuel-pusher mix during final compression is essential for achieving noncryogenic ignition with double-shell targets on the National Ignition Facility.
