The ignition of magnetized plasma driven by the pulsed power

Summary form only given. The MTF of the three stages configuration, which is on the way at LANL and Air Force in America, is harassed due to energy loss and instability from long distance transportation, while the MAGO of two stages configuration, which is improving from its old version at All-RRIEP in Russia, is facing the serious impurity washed due to plasma passing the narrow nozzle between two stages. We are proposing one stage of configuration for fusion ignition of magnetized plasma driven by proper pulsed power source. Comparing to two or three stages mentioned above, this configuration can reduce energy loss lower the damage from impurity and ease the instability due to its integrated simple geometry. The two dimensional magneto-hydrodynamic code is developed to simulate the forming process of reversed field configuration target (FRC) in this one stage of configuration. The simulating results show that the proper temperature magnetic field and plasma density can be achieved for further imploding compression, which can get several hundred electron voltage by initial 1-2 electron voltages several Tesla by initial 0.2-0.4 seed field and ten to the seventeenth or eighteenth per centimeters density by initial ten to the fifteenth or sixteenth per centimeters, individually. Based on these simulating results, a device to create the FRC target is proposed and building in China, which is supposed to be finished in next couple of years. Meanwhile, we develop one dimensional radiation magneto-hydrodynamic method for the cylindrical geometry to investigate the process of ignition. The concept of the new mechanism of ignition called the local center ignition (LCI), which is believed from the embedded strong magnetic field is proposed. The analyzing and simulating results from LCI model show that : 1) the embedded magnetic field may play a key important role on the process of ignition, 2) the shaped pulse power including the initial pulse height the pulse width and puls- rising time can affect the process of ignition, and 3) the condition of ignition with the embedded magnetic field is derived and analyzed by means of the simple analytic model and one dimensional model individually, both of them show in agreement with each other, which means that the ignition with one stage configuration in magnetized plasma can be achieved with proper conditions.The simulating results show that the proper temperature. magnetic field and plasma density can be achieved for further imploding compression, which can get several hundred electron voltage by initial 1-2 electron voltages.several Tesla by initial 0.2-0.4 seed field and ten to the seventeenth or eighteenth per centimeters density by initial ten to the fifteenth or sixteenth per centimeters, individually .
