AbstractLow temperature plasma generated by plasma needle in atmospheric pressure air has extensive application prospects in industry because the vacuum device can be dispensable. In the present paper a stable plasma plume was generated in air by using a plasma needle device. The vibrational temperature and gas temperature were investigated for the plasma plume by optical spectroscopic method. Research results show that the plasma plume generated in atmospheric pressure air can be distinguished as a strong emission area near the needle followed by a weak emission area. The light emission signal from the discharge is a pulse per half cycle of the applied voltage with a time width of several microseconds. Results also indicate that the vabrational temperature varies from 2500 to 3000 K for different emission locations. The vibrational temperature increases with increasing the distance from the needle point in the strong emission area and it reaches a peak value at a distance of about 5mm from the needle point. The vibrational temperature decreases with increasing the distance from the needle. Similarly, the gas temperature decreases from 640 K to 540 K with increasing the distance from the needle point. These results are of great importance for the industrial applications of air discharge at atmospheric pressure.
