主 题：Magnetized Target Fusion(MTF) Field Reversed Configuration(FRC) Magnetized plasma Pulsed power
摘 要：As a hybrid approach to realizing fusion energy,Magnetized Target Fusion(MTF)based on the Field Reversed Configuration(FRC),which has the plasma density and confinement time in the range between magnetic and inertial confinement fusion,has been recently widely pursued around the *** investigate the formation and confinement of the FRC plasma injector for MTF,the Yingguang-I,which is an FRC test device and contains a multi-bank program-discharged pulsed power sub-system,was constructed at the Institute of Fluid Physics(IFP),*** paper presents the pulsed power components and their parameters of the device in detail,then gives a brief description of progress in experiments of FRC *** results of the pulsed power sub-system show that the peak current/magnetic field of 110 kA/0.3 T,10 kA/1.2 Tand 1.7 MA/3.4 Twere achieved in the bias,mirror and q-pinch circuits with quarter cycle of 80 ms,700 ms and 3.8 ms *** induced electric field in the neutral gas was greater than 0.25 kV/cm when the ionization bank was charged to 70 *** H_(2) gas of 8 Pa,the plasma target of density 10^(16) cm^(-3),separatrix radius 4 cm,half-length 17 cm,equilibrium temperature 200 eV and lifetime 3 ms(approximately the half pulse width of the reversed field)have been obtained through the q-pinch method when the bias,mirror,ionization and θ-pinch banks were charged to 5 kV,5 kV,55 kV and ±45 kV *** images from the high-speed end-on framing camera demonstrate the formation processes of FRC and some features agree well with the results with the two-dimension magneto hydrodynamics code(2D-MHD).
