Abstract:
Several optical diagnostic techniques were developed to interrogate important plasma parameters including temperatures and species concentrations. In particular, a new technique of electron number density measurements based on measurements of the nonequilibrium population of the predissociative C state of NO was devised. It was found that the three-body NO recombination rate proposed by Dunn and Kang appears to be too slow by a factor 100, and that the rate proposed by Gupta et al. or Park is also too slow, by about a factor 10. This result has significant implications for the development of techniques to create and maintain elevated electron number densities in air plasmas.
