Разряд Атмосферного Давления, Поддерживаемый Миллиметровым Излучением В Волноводном Плазмотроне

In the developed waveguide plasmatron with combined gas influx, a nonequilibrium discharge maintained at atmospheric pressure by continuous microwave gyrotron radiation at 24 GHz was obtained and studied for the first time. It is shown that in the regime of argon discharge stabilization by carbon dioxide flow the temperature of electrons is 0.2-0.3 eV at gas temperature 1200-1500 K and the electron density does not exceed the cutoff value for the heating frequency in a wide power range.
