Abstract

Light emission and electrical characteristics in the early post-discharge of a high purity nitrogen streamer have been investigated. Up to the millisecond regime, both light emission and current are significant, while the voltage has decayed after several tens of microseconds. The corresponding decay time constants are 240µs and 580µs for the current and radiance, respectively, versus 3.8µs for the voltage decay. This suggests that energy transfer to high vibrational levels of N2(X1S; n) and high population of metastable N2(A3S+u ) species are important in sustaining the discharge.
