太陽粒子線
Wikipedia definition
1. Solar energetic particlesSolar energetic particles (SEP) are high-energy particles coming from the Sun which had been first observed in the early 1940s. They consist of protons, electrons, and heavy ions with energy ranging from a few tens of keV to GeV (the fastest particles can reach speed up to 80% of the speed of light). They are of particular interest and importance because they can endanger life in outer space (especially particles above 40 MeV).
