Experiments involving exploding aluminum wires immersed in argon gas and driven by a pulsed current source (in the microsecond time scale) were carried out in this work. Apart from electrical measurements, a multi-frame optical camera was used to observe the spatial and temporal distributions of the plasmas produced by the explosion. A time-integrated spectrometer and a photo-electric multiplier were used to analyze the light emitted from exploding aluminum wires. Electrical explosion of wires has been classified into three types according to current and voltage waveforms. By using photographic evidence and spectrum-based measurements, characteristics of the spatial and temporal distributions of the exploding wires associated with different experimental parameters were obtained and analyzed. Furthermore, the expansion trajectories of the exploding Al wires with different specific energy depositions are presented. It was found that more deposited energy leads to faster expansion velocities of the exploding products.Experiments involving exploding aluminum wires immersed in argon gas and driven by a pulsed current source (in the microsecond time scale) were carried out in this work.
