摘要：

The kinetic effects of electron heat transport in an imploding plasma are investigated by using the one-dimensional hydrodynamics implosion code with the Fokker-Planck equation. The Fokker-Planck equation is solved in the implosion simulation by reducing it to the multigroup transport equations. The implosion time, mass ablation rates, and compressed core plasma parameters of the simulations are compared with those of the flux-limited Spitzer-Harm model simulations and the experimental results of high-density compression. As a result, it is shown that the Fokker-Planck simulation results agree well with the experiments, in which the random phase plate is employed for the uniform implosion.
