CHARACTERISTICS OF HIGH CURRENT FIRING PULSES ON SQUIBS AND BLASTING CAPS
Abstract
Charts were available which gave the low current characteristics of Du Pont squibs and blasting caps. These charts did not extend up to the desired current levels. The objective of the test was to extend these charts to include the high current characteristics. Also an attempt was made to determine the minimum time required to fire the squibs when using short high current pulses. From this test it was determined that the E-81 Blasting Cap could be functioned in 70 micro-seconds using 140 volts supplied by a direct current arc welder. The charts which were available did not include any curves showing what the squibs and blasting caps reaction would be when exposed to radar frequencies. To determine what this reaction would be both pulsed and continuous wave power was applied to the squibs and blasting caps.
