Copper wires, 0.09mm, 0.17mm, 0.24mm in diameter and 1.2cm long are exploded in single and double connections by short-circuiting the 6 μF capacitance charged up to 7.5KV. The circuit contains 1.3H self - inductance and ignorablly small amount of ohmic resistance, but in the case of explosion under critical damping, 0.2Ω of resistance is included.
For the single wire explosion, numerical calculations for the solution of the circuit equation is carried out and it is found the time dependent solution for critical damping resistance is in complete agreement with the Ross-Zinke's experimental results. The calculation is extended to the double wire explosion and the solutions are compared with the experimental results obtained in the present work.
The spatially separated optical flashes produced in double wire explosion are detected by two photo-diodes, and their temporal separation, 0-4 μ $\sec$, depending on the conditions of explosion, is in good agreement with the results of the calculation. It is found in general the temporal separation is variable and controllerable by changing the length, diameter, kind of metal, inductance, localized indentation etc.
The present work reaffirms the series wire explosion in single and double connections are useful in sequential optical pumping of laser, rotating plasma generation and the high speed photography.
