Abstract
The radial structure of core temperature and density is very important to benchmark theory simulation codes in Inertial confinement fusion (ICF) studies. In this article, we gave a method to determinate the radial structure of core temperature and density by using the normalized intensity of core experimental x-ray image. The core emission model uses the average atom model (AA) and the radiation transport model assumes the local thermo dynamic equilibrium model (LTE). Calculated results show that: the full width at half maximum of core temperature is about 39.4μm which indicate that the hot spot diameter is such value and the full width at half maximum of core density is about 5μm. The hot spot convergence and the shell in-flight aspect ratio (IFAR) can be deduced approximately 7 and 7.5 respectively. The above assist us to better understand the implosion physics, and provide more information for benchmarking the simulation codes.
