Abstract

Abstract

A pulse forming network (PFN)discharge module and a spectroscopy system were employed to discuss the electrical explosion of copper wire.The plasma emission spectra were obtained in the wavelength range of 400-500nm by an Andor SR750spectrograph.Based on the thermodynamic equilibrium theory, the arc plasma excitation temperature was calculated by the relative line intensities.And the variation characteristic of the excitation temperature was discussed.The results show that the steady -state plasma excitation temperature by the exploding copper wire is approximately 5400K.The excitation temperature changes obviously in the prophase of the pulse discharge and it is relatively stable at the later stage of the pulse discharge.The excitation temperature difference during the whole pulse time is about 800K.
