Abstract

In thick shell implosions, most of the kinetic energy is used to assemble the cold fuel rather than to heat the hot spot. A significant increase in the hot-spot compression and reduction of the driver energy required for ignition can be accomplished by launching a shock during the final stage of the implosion. In direct-drive inertial confinement fusion (ICF), the "ignitor" shock can be launched by a power spike at the end of the laser pulse. For targets with the same adiabat and implosion velocities, the laser energy required for ignition is significantly lower for shock-ignition ICF than for standard ICF.
