Abstract
It was reported that the fuel core was heated up to ~ 0.8 [keV] in the fast ignition experimentswith 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 schemeperformance, 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 electronsgenerated by the laser-plasma interaction were too hot to efficiently heat the core and we got only 0.096 [keV] temperature rise. Including the density gap at the contact surface between the cone tip and theimploded 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.
