Abstract: A physical model of heating and ignition of magnetized plasma is presented, which is analyzed by 1D 3T MHD Lagrange code in the metal liner driven by pulsed-power. The analysis includes the procedure of metal liner implosion driven by pulse, the impact of different driving source within magnetized target warming on, the effects of embedded magnetic field and the pre-heating temperature for magnetized plasma warming during Z-pinch process, the initial parameters for ignition and energy output. The physical mechanism is introduced in which the magnetic field increases the energy deposition and reduces energy loss through heat conduction electron and ionization. The simulation indicates that a strong magnetic field (over 1000 T) is produced during the implosion procedure and obvious heating-up (about 4 keV) can be acquired by selecting 5 T embedded magnetic field and 250 eV preheat temperature for the target. We get the order of one thousand T magnetic field and the energy output about a hundred kJ/mm level when the initial parameters, including embedded magnetic field, pre-heating temperature, fuel density, liner scale, pulse amplitude and loading time, are under certain conditions.
