摘要

本研究針對太陽質子事件的環境影響尤其是內部輻射帶並且以范艾倫探測器的觀察進行分析的。選擇范艾倫輻射帶運行期間發生的太陽質子事件為2013年至2015年，並且使用相對質子光譜儀分析這些事件所被觀測的質子微分通量。分析結果顯示，當太陽質子事件發生時，質子微分通量增加，這些增加的開始時間早於GOES 13觀測所定義的太陽質子事件的開始時間、內部輻射帶也發現具有明顯差異，事件發生前的擴張、發現質子微分通量的值隨著內部輻射帶中L殼增加而線性減小。本研究的結果可以應用於內部輻射帶附近進行高能粒子任務的早期預警。

In this study, the environmental impact from the solar proton events, specifically on the inner radiation belt, are analyzed based on observations by the Van Allen Probe. The solar proton events occurred from 2013 to 2015 are selected and data of proton recorded by Relativistic Proton Spectrometer at these event times are analyzed. The analyzed results show that the proton differential fluxes increases when solar proton events occurred, and the onset time of these increases are earlier than the onset time of solar proton events defined by observations from GOES 13. The inner radiation belt is also found to have distinct expansion before the event occurred. The values of the differential fluxes are also found to decrease linearly as the L-shell increases in the inner radiation belt. Results of this study can be applied to early warning of energetic particles space missions performed near the inner radiation belt.
