 note = {Preliminary spectroscopic measurement of electron temperature of arc plasma which strongly related to electrical conductivity was carried out to evaluate the range of proper amount of external capacitor. Using the solar array coupon with the flaw simulating debris impact on the face sheet beside one cell edge, we observed a lot of non-permanent sustained arcs between the cell and the substrate along with the primary arcs. Comparing the spectra of primary arc and non-permanent sustained arc, spectra of non-permanent sustained arc case contained many species compared with the case of primary arc only. Aluminum and ion atoms and silicon ion that included in substrate, electrode and cell were observed. These materials would be vaporized by joule heating of arc plasma. Also, time variations of electron temperature in each discharge mode using relative intensity ratio technique for C(sub 2) Swan system spectra. Primary arc temperatures at peak current was about 5,000-15,000 K and were not much difference whether non-permanent sustained arc occurs or not. The temperatures of the non-permanent sustained arc were up to about 7,000 K and lower than that of primary arc., 資料番号: AA0049206037, レポート番号: JAXA-SP-05-001E},
