Abstract
The spatial temporal evolution of the electromagnetic instability and thermal flux reduction in anisotropic plasmas were investigated by using electromagnetic relativistic particle-in-cell simulations. The onset and nonlinear saturation process generating mechanism of the self-generated magnetic fields and physical essence of electron thermal flux reduction were discussed. Numerical simulations show that: In an anisotropic plasma electronic return and internal transport of hot electrons to the target in the process of formation of self-generated magnetic field on the epithermal electron beam heat flux carried by inhibition. These results may be important for understanding of the self-generated magnetic fields generating mechanism, electron thermal flux reduction and electron propagation in fast ignition physics.
