Insights into the peculiar field structure of a recent diffuse discharge under extreme voltage conditions by electric field induced second harmonic generation and optical emission spectroscopy

Résumé

The axial temporal evolution of the electric field of a diffuse nanosecond air discharge is measured with high resolution (<100 ps). This discharge is generated at atmospheric pressure in a pin-to-plane configuration for voltages ranging from 20 to 85 kV The electric field is derived by field induced second harmonic generation. It is shown that for peak voltages above 56 kV, the electric field behind the field front increases with voltage and exceeds the ionization threshold at 85 kV. Results are compared to recent measurements [1].
