Modeled Diagnostics For Detonator Characterization

A novel diagnostics method to measure the detonation electric effect was tested and verified against computerized models. Where standard diagnostics are used to measure currents, timings, and other particularly useful quantities, a novel copper antenna was created in order to detect and measure RF-signals (radio frequency) from high explosives (HE). With detonation velocities, pressures, and arrival times resolved from multiple diagnostics, including Rogowski coils5, Polyvinylidene Fluoride (PVDF) gauges, and Current Viewing Resistors (CVR), models created with ALE3D Hydro Codes then predict detonator performance and further qualify the copper antenna’s integrity as a capable diagnostic in quantifying RF emissions.A novel diagnostics method to measure the detonation electric effect was tested and verified against computerized models.
