However, the densities of N2 in sub-LEO are higher than LEO, and the durability of FEP in sub-LEO environment is still unclear. In this study, simultaneous exposure experiment of AO and Ar, which is simulating N2 collision in sub-LEO, was performed on FEP/Ag film samples. It was confirmed that the erosion of FEP by hyperthermal Ar beam was greater than that by AO beam. In addition, the synergistic effect was not be confirmed at the simultaneous exposures of AO and Ar. The importance o f N 2-induced erosion of FEP in sub-LEO was commented., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1730013007, レポート番号: JAXA-SP-17-006}, pages = {53--57}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {超低軌道宇宙環境におけるFEP/Agフィルムの劣化原因に対する考察}, volume = {JAXA-SP-17-006}, year = {2018} }
