FIG. 2.

Waveforms of the voltage across the wire , wire current measured with a shunt (solid lines), and currents through auxiliary electrodes and (dashed lines), recorded at a charge voltage of 30 kV and at a distance from the auxiliary electrodes equal to 5 mm for Al wires (a) in diameter and preheated W wires (b) in diameter. is a time between the time of peak voltage and the start of the current through the auxiliary electrode.

FIG. 3.

Curves showing the expansion of the corona plasma for an exploded Al wire (boxes), an unheated W wire (circles), and a preheated W wire (asterisks) at a charge voltage of (a) 10, (b) 20, and (c) 30 kV.

FIG. 5.

Curves showing the expansion of the corona plasma for an exploded preheated W wire. Solid lines represent the simulation data for a charge voltage of (a) 10, (b) 20, and (c) 30 kV, respectively; boxes, asterisks, and circles represent the experimental data for a charge voltage of 10, 20, and 30 kV, respectively.
