Paper Title:
A Study on an Initiation Technique of Small Amount of Explosive
  Abstract

High explosives are useful material to generate great amount of energy in short time. Since controlling their releasing energy is hard, the use of explosive is limited to specific fields and industries. However, the reduction of the explosive powder mass uses at a time makes the handling safe. And use of explosives in a continuous producing process leads the new utility of the explosion. Based on this concept, we enclosed small mass explosives with a polyethylene sheet and initiate them by using metallic foil explosion. We have also developed the system that can generate small explosion continuously. Since it was not easy to initiate a small amount of explosive steady, we had initiated them by metallic foil explosion using a power-supply unit of capacitor bank with 2500J (20kV). In present study, we tested the initiation of a small amount of explosive using a comparatively small power-supply unit of capacitor bank with 4.5J (600V) and that of 2J (1kV) to apply to the general use. In this paper, result of experiments and the conclusions are shown. We observed the perfectness of explosion by using omnidirectional microphone. It is concluded that initiation of explosives enclosed with polyethylene sheet by small power supply unit at 2J (1kV) is possible, while the explosion was not perfect.
