  • Temperature Measurement of Discharge Field by Emission Spectroscopy for the Modeling of the DC Discharge Field

抄録

<p>In this study, the temperature measurement of the DC discharged plasma has been conducted by an emission spectroscopy with the spectrum matching method. The calculation code which was developed by our group was used for the theoretical spectrum database construction for the spectrum matching method. The second positive band of the nitrogen molecule and the first negative band of the nitrogen molecular ion were under consideration as the electronic transitions in the present calculation. Before constructing the theoretical spectrum database, the verification has been conducted by the comparison between the calculated theoretical emission spectrum and the literature results. As a result, the calculated theoretical emission spectrum generally agrees the overall shape of the spectrum of the literature results. The temperature was determined from the measured spectrum by applying the spectrum matching method under the condition in the initial pressure 2 [kPa] for air as a test gas. As a result, the rotational temperature of N2 was 1900 [K]. This temperature is valid from the view point of the comparison with the other experimental result using the similar experimental facility.</p>
