Progress on the physics of ignition for radiation driven inertial confinement fusion (ICF) targets

摘要

Extensive modelling of proposed National Ignition Facility (NIF) ignition targets has resulted in a variety of targets using different materials in the fuel shell, using driving temperatures which rang efrom 250 to 300 eV, and requiring energies which range from less than 1 MJ up to the full 1.8 MJ design capability of the NIF. Recent experiments on Nova have shown that hohlraum walls composed of a mixture of high Z materials could result in targets which require about 20
