–Title–
Simulation study of high areal density compression with solid target implosion for fast ignition

–Abstract–
For the laser fusion, the formation of a highly compressed and hot core is required. In the fast ignition scheme, since the compression and heating processes are not coupled strongly, solid target implosion is a candidate because it is less sensitive to the hydrodynamic instabilities. We have designed a low isentropic implosion with multi-step laser pulse, using 1-D and 2-D radiation hydrodynamic simulations. In this talk, I will present these results and also discuss some issues with this method from the perspective of fast ignition.
