2019 15th Hypervelocity Impact Symposium.
Using a Voitenko accelerator, a series of experiments were performed with the goal of attaining shock velocities in gases approaching 90 km/s. The basic apparatus comprised a hemispherical bowl filled with a gas at atmospheric pressure; a metal pisto

A strong dependence of the dynamic resistivity of Explosively-Formed Fuses (EFF) on metal temper is reported. The explosively driven switch has been extremely effective in a wide range of large-scale experiments but good, predictive, computational mo

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 anten

It has been shown that the temperature of explosively generated plasma (EGP) is of the order of 1 eV and plasma ejecta can be focused to achieve velocities as high as 25 km/s. Proof-of-principle tests were performed to determine if EGP could be used

A series of 1-D isentropic-compression experiments (ICE) has been initiated using the high-explosive pulsed-power (HEPP) system. Accurate high-stress isentropic equation-of-state (EOS) data had been reported using the HEPP-ICE system. A number of imp
