Gas temperature measurements in an atmospheric pressure micro plasma jet

الملخص EN

The rotational (TR) temperature of N2 molecules, which is an inductor to gas temperature, was measured in atmospheric pressure micro-plasma jet in He with trace amounts of O2 excited by radio-frequency (RF) power.

The influence of different parameters such as input RF power to the plasma, different O2 admixtures ratio and the RF pulse modulation frequency, on the gas temperature Tg was investigated.

The results show that the control of the operating conditions of the plasma jets enables the tailoring of gas temperature.
