Abstract

Abstract

In this paper, we studied the program implosion process and the influence of the magnetic field under a high-energy density state on charged particles and the mechanism of the compression process, using the MHD equations and finite difference method. The results show that the implosion process parameters meet the following conditions:the electron temperature plasma (50 keV), the pressure (1 TPa), the particle number density (10²⁴ cm^-3). The liner material had a major influence on the confined time and ignition conditions; at the same time, the electronic thermal conductivity was reduced by more than 100 times in the absence of a magnetic field when the magnetic field was greater than 5 T, and the ion thermal conductivity also experienced a significant decrease in the compression peak. The alpha particle energy deposition density in the 5 T embedded magnetic field was relatively raised by more than about 200 times than in the 1 T embedded magnetic field. Also, it was found that magnetization hindered implosion compression process to a certain extent.
