This thesis research explores a new and novel method to create an ESD resistant, robust exploding wire initiator for energetic material applications. Metallized, capacitor grade polypropylene film was used as the new surrogate exploding wire. Its characteristics, such as a long path length, and sheet resistance made the metallized polypropylene film more ESD resistant than a wire of uniform diameter. The metallized polypropylene film was tested under capacitive discharge conditions to determine plasma temperature, low input energy, and a fast transition time from solid metal to the plasma state. The transition, or dwell time from solid metallization to the plasma state was measured to be less than 200 ns. The temperature of the aluminum vapor plasma was estimated utilizing a theoretical model with the experimental data collected. The model yielded temperatures that ranged from 3000°K to 10000°K which were within the limits of the desired application.
