Axial electric field component in a fast ionization wave in nanosecond pulsed nitrogen discharge at 20-100 mbar
Résumé
The axial electric field component in a fast ionization wave in ns tube discharge in N2 at 20-100 mbar is measured by ps second harmonic generation with the temporal and spatial resolution of 200 ps and 0.5 mm respectively. From absolute calibration by current shunts, the peak axial electric field, 8-11 kV/cm, shows a weak dependence on pressure, with the peak reduced electric field ≈2000 Td at 20 mbar. For the same voltage conditions, pressure reduction from 100 to 20 mbar steepens the wave front from 3.0 ns to 1.0 ns FWHM.
