Abstract : The purpose of this thesis was to design, build, and test a high voltage detonator initiation system capable of firing a series modular detonator array. This initiation system was designed to optimally fire a detonator array of 25 detonators, but is capable of firing detonator arrays of different lengths. The procedures used to develop this initiation system included four steps. First, the minimum burst current and the maximum current frequency required for successful detonator intiation were determined. Second, the equivalent circuits of the detonator array/return conductor combination and connector cable were derived. Third, the design of the initiation system was made. Fourth, the initiation system was built and tested. The testing of the initiation system using array sizes of 3 and 25 detonator models was limited. These tests showed that the firing switch had an average delay time of 733 and 725 nsec respectively for the small and large arrays.
