Electron Temperature and Density Measurement of Plasma Jet in Atmospheric Pressure (original) (raw)

The optical description of the system was done by recording emission spectrum for wavelengths emitted from plasma in spectral range (160-960) nm, then analyzing this spectrum. Finally the thermal characteristics were done by measuring the temperature of flowing gas at various flow rates for deferent distances from the ending of needle which generates electric discharge. Also, a study of effect of flowing gas along plasma discharging was done and the temperature of electron for plasma was estimated spectrally about 0.61 eV and the density of electrons was about 4.38x10 15 cm-3 .
