Under the background of new clear energy requirement based on magnetic inertial confinement fusion (ICF), the present project is to study the energy transport and relevant events in strongly magnetized high-energy-density laser-produced plasma, in which the issues are involved: 1) locally magnetized properties of laser-produced plasma under seeded and self-generated strong magnetic field topology, such as the magnetic field amplification and its saturation by magnetic flux compression, the dependent relations between magnetic flux compression and parameters of laser-plasma; 2) applying the generalized Ohm’s law in the MHD framework to explore the self-generated magnetic reconnection driven by two laser beams in plasma, energy conversion resulted from magnetic explosion process, and new mechanism of electron acceleration and transport by magnetic explosion; 3) characteristics of hot electron transport resulted from sideward Raman and weak-damped two-plasmon decay instabilities and competition between the processess in the developing of instabilities under the condition of strong topologic magnetic field, which will be experimentally examined by ultrafast time-resolved diagnosis; 4) harmonic radiation driven by strong laser field near the critical density and the radiation transport under the condition of strong topologic magnetic field. The investigations for these issues are of significance for further understanding the developing magnetic assistant ICF implosion and even for the design of new imploding targets.
