Dependence of the Methane Decomposition Factor in Cold Electron-Beam Plasma upon Input Power

Resumo

A device for creating a cold nonequilibrium electron-beam plasma in a supersonic gas flow has been developed. A method proposed for generating this plasma is described. It has been established that methane is activated by direct electron impact in electron-beam plasma under specified conditions. It has been shown that applying an external electromagnetic field leads to a significant increase in the methane decomposition factor due to the involvement of secondary, low-energy beam electrons accelerated in the electromagnetic field.
