The effect of wire diameter on the initiation of PETN by exploding platinum wires was investigated. A one microfarad capacitor charged to 2,000 volts was used as the energy source for exploding the wires. The diameter of the wire can be chosen so as to favor time reproducibility of explosion, reliability of effecting detonation, or vigor of the bridgewire output. The wire with the most vigorous shock output when tested in air is not necessarily the most efficient for effecting detonation when PETN is loaded on the wire.
