Including a density jump between a cone tip and imploded plasmas, we have performed preliminary FI3 simulations for fast ignition with cone-guided targets, and found that the density gap with 2n was effective at heating the core. But this effect is not successful under the realistic parameters for recent fast ignition experiments. Even so, it was found that the core could be heated up to 0.44 keV, but we could not get core temperature observed in the experiments, 0.8 keV. From those results, it should be emphasizes that integrated simulations under realistic conditions are essential for the fast ignition research.
