摘要
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。
The space environment effect detector with red-blue optical sensitivity solar cells, including GaInP2 and GaInP2/GaAs/Ge solar cells, can be used for detecting contamination, atomic oxygen and radiation environment and the related effects. With the detector, a large number of effective detecting data are obtained through XY-1 developed by China Academy of Space Technology. The detected data from the space environment effect detector in one year are analyzed and it is concluded that the power of the contamination detector is declined by 2.7%, the equivalent contamination deposited mass is 2.23×10^-5 g/cm^2 and the average value is 6×10^-8 g/cm^2 per day. The atom oxygen flux is 9.7×10^20 AO/cm^2 in eleven months at the altitude of 499.226 km. The cumulate irradiation dose （equivalent 1 MeV electron fluence） of the radiation effect detector （with three junction GaAs solar cells） for 1 year in orbit is 5.49×10^11 e/cm^2.
