Abstract :
We present nitrogen microwave blown-out plasma at atmospheric pressure and its emission spectra with their spatial distribution. The plasma had a symmetric conical shape until it collapsed to a funnel-like shape at high gas flow rates. We observed the emission of N2, N2 +, CN and NO: their Abel-inverted emissivity increased with increasing power and decreased with plasma radius.
