Abstract

Images showing the spatial distribution of nitric oxide (NO) following propagation of a 30 ns pulsed, negative streamer between needle-plane electrodes, in 25 parts per million (ppm) NO seeded air, are reported. The images were generated using laser-induced fluorescence, and show uniform destruction of 10 ppm NO between the cathode and anode. This evidence shows that processes associated with the propagating streamer are responsible for uniform destruction of NO throughout the electrode gap
