The ratio of released coefficient is identified with spectral intensities measured by a spectroscope. This time by using this character, the temperature of the plasma in Ar at 0.1 Mpa was evaluated by the ratio of the released coefficient to be 10,500K at 100A. The electron density was measured by the Stark method to be 1.44 × 1023m−3 at 100A. The temperature and electron density are roughly constant regardless of arc current between 50–100 A. The composition of particles was evaluated by using three equations such as Saha equation, state equation and the condition that charges are neutral. In result when the temperature is 10,500K, most of tungsten atoms are ionized. But most of Argon ones are not ionized because the ionization energy of tungsten is much lower than that of Argon. 【査読有】 中央大学理工学研究所 2003-03-31 jpn departmental bulletin paper VoR https://doi.org/10.24789/00001245 https://chuo-u.repo.nii.ac.jp/records/1255 10.24789/00001245 1343-0068 中央大学理工学研究所論文集 8 11 20 https://chuo-u.repo.nii.ac.jp/record/1255/files/1343_0068~8~~11.pdf application/pdf 618.9 kB 2019-04-22
