AB: The refilling of the H⁺ and He⁺ plasmaspheres is simulated over long times (days) using the SAMI2 (Sami2 is Another Model of the Ionosphere) code[1]. It is shown that the plasmaspheric He⁺ population reaches saturation more rapidly than the H⁺ population and that, if left undisturbed, the H⁺ density at L=3 can continue to increase for as long as 10 weeks.
