低轨道卫星辐射带下高能电子增强和X射线污染

Energetic electron enhancements below the radiation belt and X-ray contamination at low-orbiting satellites

Alla V. Suvorova, Alexei V. Dmitriev, Chien-Ming Huang

摘要:

这项工作涉及在相对低纬度的低轨道卫星上进行高能天体物理测量时电子引起的污染问题。我们展示了1999年至2012年期间NOAA/POES低轨道卫星群观测到的能量范围为30-300 keV的高能电子增强的统计分析结果。我们展示了由不同类型的太阳风驱动器所引起的大的和中等的持久增强的地理分布。

英文摘要:

The work concerns a problem of electron-induced contaminant at relatively low latitudes to high-energy astrophysical measurements on board the low-orbiting satellites. We show the results of a statistical analysis of the energetic electron enhancements in energy range 30-300 keV observed by a fleet of NOAA/POES low-orbiting satellites over the time period from 1999 to 2012. We demonstrate geographical distributions of great and moderate long-lasting enhancements caused by different type of the solar wind drivers.
