摘要
木星系辐射环境包括高能电子和质子、重离子、等离子体、极光粒子等。另外,Galileo卫星的辐射环境也是木星探测任务的关注重点。文章基于木星特殊的高辐射、低光照、超低温环境特点,分析了包括总电离剂量、内带电、单粒子、位移损伤等辐射效应,识别出了木星辐射环境效应中的研究重点,并针对总剂量效应讨论了木星系探测器屏蔽材料的选择和屏蔽结构的设计。
The radiation environments of the Jovian system include： high energy electrons and protons, heavy ions, plasmas, auroral particles, etc. Additionally, the radiation environments near the Galilean satellites are also of interest. According to the characteristics of the special high-level radiation, the low-intensity sunlight, and the extremely low temperature in the Jovian system, the related radiation effects are analyzed, including the total ionizing dose effect, the internal charging effect, the single event effect, and the displacement damage effect. The choice of shielding materials and the design of shielding vault in the Jovian system mission are discussed focusing on the total ionization dose effect.
