Abstract :
The fusion of magnetized plasma is a hot topic in recent years, in which MTF (Magnetized Target Fusion) is a new approach to producing fusion power,. In this paper, we investigate the simple model as well as 1D MHD simulation to study the parameter space of the ignition condition for the magnetized plasma. The detailed analysis and simulation results show that the strong magnetic field will suppress the energy loss of the thermal conduction and increase the energy gain from alpha particle deposition during the compression. We obtain the parameter space of confinement parameter, magnetic field strength and the plasma temperature for high-temperature magnetized plasma to reach the ignition condition. The magnetic field configurations and radical temperature profiles of the magnetized plasma are obtained with 1D MHD with suitable external pulsed power. It shows that the ignition conditions computed from 1D MHD simulation is in accordance with the simple analytic model.
