Description
The solar modulation of Helium isotopes (Helium-3 and Helium-4) is studied and compared to observations at the Earth. This is done from the period of minimum solar activity from 2006 to 2011, up to the period of solar maximum activity from 2012 to 2015. Computed spectra are compared to the precise measurements of Helium-3 and Helium-4 fluxes measured by the PAMELA and AMS-02 space missions between July 2006 and December 2015, spanning time frames that include the solar magnetic field reversal epoch. Insight gained from this comprehensive modeling, with a three-dimensional drift model, about the relative roles of the four main modulation processes over the mentioned period will be shown and discussed.
