Effect of temperature gradient on the non-equilibrium rate of flux emitted by plane gold wall

Abstract

In the theoretical and experimental research of radiation transport in inertial confinement fusion (ICF), the radiation spectrum in the foam cylinder can be changed by the surrounding high-Z wall. In this paper, we simulated and studied the property of flux emitted by the high-Z wall using 1-D plane model. Our work shows that the gradient of electron temperature is the reason why spectrum of flux emitted by the high-Z wall deviates from equillibrium. In order to quantitatively study the property of flux emitted by the high-Z wall, we define the non-equilibrium rate and deduced its estimating formula in the temperature scale of ICF experiment.
