Research Abstract

In order to achieve the high dense plasma core and efficient heating in the fast ignition scheme of inertial confinement fusion, I have developed one-or two-dimensional radiation hydro simulation codes. I have investigated the high dense implosion and cone target physics, including the condition of interior of cone target.
