Features of the Explosion of Conductors from Various Materials Based on Electrotechnical Measurements

This work presents a detailed analysis of oscillographic data obtained in experiments on the nanosecond explosion in air of thin wires made of Ag, W, Pd, and Ti—metals belonging to different classes (copper, tungsten, and nickel groups) in terms of their electrical and thermal properties. Features of electrical signals characteristic of explosion scenarios corresponding to each of the groups are discussed. The experiments are conducted on a capacitor-type setup with a total stored energy of up to 20 J (C = 0.1 μF, Imax = 10 kA, dI/dt ~ 50 A/ns) at a charging voltage of 13 kV. This work is the first stage of a study aimed at establishing the mutual influence of the generator parameters serving as the source of explosion energy and the loads used.
