Abstract :
This paper presents experimental spectra resulting from simple exploding wires used in railgun plasma production and shows initial comparisons with basic theory. Exploding wire spectra have been obtained by discharging a 1200 /spl mu/F capacitor bank at a voltage in excess of 1 kV through both metal wires and carbon fibres. The spectrometer used has enabled spectra to be recorded in the visible and ultraviolet wavelength regimes. Furthermore, the use of a charge coupled device (CCD) as the recording medium allows the time resolution of the spectral emission. A maximum of 512 spectra per discharge is possible, with a minimum acquisition time of less than 10 /spl mu/s per spectrum. The transient current in the exploding win was monitored by a Rogowski coil. Analysis of the experimental data has enabled the fluctuations in the spectral intensity to be related to the development of the electrical discharge.<>
