Scheme of coaxial microwave gas-discharge plasma source based on a
“plasma resonance” phenomenon is presented. Possibility of conditions
realization at which energy of accelerated in the “resonance” electrons
goes into ionization processes (in volume of chamber outside of
“resonance” region) is discussed. Results of experimental investigation of
a coaxial microwave plasmatron in which “resonance” mechanisms have been
manifested are presented. A plasmachemical reactor based on a “resonance”
plasmatron is described. The data on plasmachemical decomposition of
CF2Cl2 are displayed.
