Abstract
The time variation of the near‐infrared radiation intensity from restrikes of exploding wires was studied for different currents and wire materials. The results show that the peak near‐infrared radiation intensity form the restrike is proportional to the first current maximum and that the radiation reaches its peak slightly after the first current maximum. By using the computed values of the particle density and the temperature of the discharge plasma, it was possible to show that the reason why the radiation from the discharge reaches its peak near the first current maximum may be that the ionized particle density in the discharge channel reaches its peak near the first current maximum.
