Detonators are fundamental to most explosive systems, yet the detonators themselves are rarely diagnosed to determine how well they function or why they fail. To remedy this, various electrical diagnostics were explored, including: Rogowski coils for high fidelity detection of changes in electrical current in explosive bridgewires and how they relate to detonator performance; and radio frequency (RF) antennas to detect any electromagnetic emissions associated with reaction and growth in the explosives. A new type of Rogowski coil is described and some interesting phenomena were detected with the radio frequency antenna.
