Electrical and Photographic Characterization of Low-Intensity Capacitor Spark Discharges.
Abstract
Some properties of the gaseous discharges normally used in electrostatic initiation of primary explosives are determined from electrical and photographic studies. It is shown that the magnitude of the postbreakdown current can determine the form of the discharge. For currents larger than about 0.3 amp, the discharge is essentially an arc characterized by a low (15-30 v) voltage drop across the gap. For currents less than 0.1 amp, the discharge is essentially a spark or glow discharge characterized by a voltage drop of approximately 300 volts across the gap. In both cases, the voltages and the transition current are only slightly affected by variations in the gap length.
