The Electrical Behavior of Fine Wires Exploded by a Coaxial Cable Discharge System

PDF Version Also Available for Download.

Description

The characteristic square output currert pulse from a discharging coaxial cable has been utilized to explode wires of 1-mil diameter. The primary pulse duration was 3 mu sec and was variable in amplitude to a maximunn of 600 amperes. Voltage and current waveforms were recorded on a high-speed oscilloscope. Resolution of the system is better than 10/sup -8/ sec, thus enabling accurate determination of the resistance history of the malerial being studied. A survey of the behavior of various metals is presented, and the results of certain parameter studies, such as, geometry, external environment, and current density, are discussed.

Description

The characteristic square output currert pulse from a discharging coaxial cable has been utilized to explode wires of 1-mil diameter. The primary pulse duration was 3 mu sec and was variable in amplitude to a maximunn of 600 amperes. Voltage and current waveforms were recorded on a high-speed oscilloscope. Resolution of the system is better than 10/sup -8/ sec, thus enabling accurate determination of the resistance history of the malerial being studied. A survey of the behavior of various metals is presented, and the results of certain parameter studies, such as, geometry, external environment, and current density, are discussed. It is shown that end effects contribute to the measured length of the sample, and that the energy to burst is dependent on current density. A new experimental system capable of producing square current pulses with an amplitude of 2000 amperes is described. (auth)
