Abstract
This paper is devoted to the results of diagnostic research of pulsed microwave discharge at atmospheric pressure. The discharge is used for plasma catalytic processes of hydrocarbon conversion to accelerate chemical reactions. The results of spectroscopic measurements of time dependencies of electric field magnitude, charged particles densities and gas temperature in the discharge plasma are presented. It is shown that the discharge evolution is well described by the «microwave streamer» mechanism followed by heating of the «streamer» and abrupt growth of its plasma ionization degree. Relying on the obtained data it is shown that the chemical process is accelerated in weakly ionized peripheral areas ofthe discharge channels.
