Abstract
To investigate the core plasma heating in fast ignition
targets, we recently developed a two-dimensional relativistic Fokker-Planck
code "RFP-2D" for fast electron transport in dense plasmas. In the present
study, we have coupled RFP-2D with a 2D hydrodynamics code for bulk plasma
and analyzed the core plasma heating by assuming a condition similar to that
in the GXII-PW laser experiments at ILE. It was found that when the source
beam electrons enter the dense core region with "low" (<1 MeV) average
energy and a Super-Gaussian spatial distribution, the core plasma can be
heated above 0.8 keV at maximum, which is almost the same temperature as
measured in the experiments.
