Abstract:

The need has arisen in the Naval Ordnance Laboratory for an apparatus to measure the susceptibility of explosives and pyrotechnic materials to initiation by a static electrical spark discharge. By charging a known condenser to a known voltage, a calculable quantity of energy can be dissipated in a spark through an explosive sample. After some preliminary work at the Naval Ordnance Laboratory and after the inspection of the apparatus at the Bureau of Mines, it was decided to build an apparatus of the design presented. Although the basic circuit is quite simple, much care was taken to eliminate loss of charge that might arise from corona or surface leakage.
