The spacecraft thermal protection materials polyimide and polyethylene terephthalate were chosen, and the total electron emission yield was measured by a small cylinder collector while the photoelectron emission yield by a vacuum ultraviolet lamp with 5 narrow band filters. Meanwhile, the pulse shot and sample scanning method were utilized in both systems to prevent surface charging phenomenon. According to the orbital environments, the comparison of total electron emission yield between virgin and ultraviolet irradiated samples was carried out, and the angular dependence of photoelectron emission yield was also tested and analyzed. The electron emission yield of various surface materials under different constraint conditions can establish the database, which will finally be used in the Multi-utility Spacecraft Charging Analysis Tool (MUSCAT) to accurately calculate the spacecraft surface potential., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0061891021, レポート番号: JAXA-SP-12-017},
