Abstract

Two copper wires, 0.017cm and 0.024cm in diameter and both 1.2cm long, connected in series are exploded by discharging a capacitor of 6;1F, charged to 7.5 KV, and the two light flashes with short duration and time separation are observed. They are detected by two cameras which take the photographs of a chopper aperture revolving at the speed of 42 rps. From the circuit equation, the prevaporization solution is obtained by the iteration method applied three times. However, the convergence of the power series is found poor. Then, a computer calculation is made to obtain the vaporization time for the two wires. The time separation of the two optical flashes are found to be 2.2 psec which agrees fairly with the value about 3 l.sec obtained by comparing the two photographs.
