Core condition studies of radiation driven implosion for maximum compression time are the key contents of inertial confinement fusion research. Core conditions refer to the electron temperature and mass density in core region. The spatial distribution of core emission is calculated based on local thermal equilibrium by Multi one-dimensional simulation of core temperature and density. Assumption is made that the core temperature and density distributions each meet a Gauss distribution. Peak values and full widths at half maximum of temperature and density spatial distribution can be inferred by parameter optimization. The data-processing for implosion experiment on Sheng-GuangIII prototype facility indicates that the peak values of temperature and density are 1.7 keV and 1.2 g/cm3 respectively. The full widths at half maximum of temperature and density distribution are 20 μm and 18 μm respectively.
