Energy dependence of the fraction of protons of ionospheric origin in the ring current

摘要: The energy dependence of a fraction ring current protons ionospheric origin is calculated using the AMPTE/CCE data for typical strong magnetic storm (max|Dst| ≈ 120 nT). It shown that this monotonically decreases from ∼ 83 to 25–30% with an increase in proton 5 315 keV at L = 6–7 (L McIlwain parameter) and 30–40% 40–50 corresponding maximum density 6–7. demonstrated core 3.7–4.7) was enriched by solar E 10–200 during active phase (the effect reached 20–50 keV).
