红蓝光敏太阳电池空间环境效应探测器利用镓铟磷和三结砷化镓太阳电池来探测空间污染、原子氧和辐射环境及效应,搭载在中国空间技术研究院自主研制的“新技术验证一号”卫星上。文章通过分析红蓝光敏探测器在轨1年时间的探测数据,得到如下结论:红蓝光敏探测器污染电池板功率下降2.7%,等效污染累积增加量2.23×10-5 g/cm2,日均6×10-8 g/cm2;原子氧探测器在轨道高度499.226 km运行11个月,原子氧积分通量探测数据为9.7×1020 AO/cm2;辐射效应探测器(三结砷化镓太阳电池)在轨1年后累计接受辐射剂量(等效1 MeV电子注量)5.49×1011 e/cm2。
Red-blue photosensitive solar cell space environment effect detector using gallium indium phosphide and triple junction gallium arsenide solar cells to detect space pollution, atomic oxygen and radiation environment and effect, carried by the China Academy of Space Technology independently developed “new technology verification One ”satellite. By analyzing the detection data of the red-blue photodetector on orbit for one year, the following conclusions are drawn: The power of the contaminated panel by the red-blue photodetector drops by 2.7% and the cumulative increase of the equivalent pollution by 2.23 × 10-5 g / cm2, (6 × 10-8 g / cm 2). Atomic orbital oxygen detector was operated at orbital altitude 499.226 km for 11 months. The detection data of atomic oxygen flux was 9.7 × 10 20 AO / cm 2. The radiation effect detector (triple junction gallium arsenide solar Battery) accumulated radiation dose (equivalent 1 MeV electron fluence) 5.49 × 1011 e / cm2 after one year in orbit.
