| Outline of Final Research Achievements |
The author aimed to derive the relation between the spectroscopic measurement and the change of electron temperature (or EEDF) and electron density of the plasmas. Its theoretical establishment was carried out, and the rate equations of the theoretical model was created to improve the agreement of the predicted value of the electron temperature and density from the optical emission spectroscopic measurement of the pulse discharge plasma. In other words, the present policy was set to explore the specific possibility of determinining plasma parameters from optical emission spectroscopic characteristics. For low temperature plasmas of argon, nitrogen, oxygen, and hydrogen, the author discussed the self-consistency of the excitation kinetics in the plasmas and the dependence on the discharge condition of electron temperature (or EEDF) and electron density, based on the spectroscopic measurement determined by the model.
