Investigation of the Resistance and Inductance of Planar Wire Array Z-Pinch at the Qiangguang Accelerator

摘要

The resistance and inductance of a wire array during an implosion are very important parameters of interest to researchers.A variety of inductances and resistances directly affect the kinetic energy and resistance heat energy coupled from a pulsed-power generator.In this paper,the inductance and resistance of a planar wire array during the Z-pinch process are analyzed.The inductance is calculated from the data obtained by a time-resolved soft X-ray framed camera,while the resistance is calculated through the voltage and the current of the wire array load combined with the variety of the inductance.The results show that the resistance of the load increases with the development of the implosion,and reaches its maximum at 0.29±0.16 near the pinched time.
