Abstract
It was reported that the fuel core was heated up to ∼0.8 keV in
the fast ignition experiments with cone-guided targets, but they could not
theoretically explain heating mechanisms and achievement of such high
temperature. Thus simulations should play an important role in estimating
the scheme performance, and we must simulate each phenomenon with
individual codes and integrate them under the fast ignition integrated
interconnecting code project. In the previous integrated simulations, fast
electrons generated by the laser-plasma interaction were too hot to
efficiently heat the core and we got only 0.096 keV rise of temperature.
Including the density gap at the contact surface between the cone tip and
the imploded plasma, the period of core heating became longer and the core
was heated by 0.162 keV, ∼ 69% higher increment compared with ignoring
the density gap effect.
