Nanosecond electric explosion of a tungsten wire in different media

The effect of surrounding media of different densities and electric strengths on the heating dynamics of a micron wire during its nanosecond electric explosion is investigated. Tungsten wires with diameters of d = 25-50 mu m were exploded in air and water at a current rise time of (dI/dt) similar to 10(10) A/s. The diagnostic complex is described.
