A Simulation Study of Galactic Proton Spectrum Observed with Changing Solar Activity

Project Description:

Measurements of cosmic-ray isotope fluxes by spacecraft missions, such as PAMELA, AMS02, and HEPD01, have generated interest in studying solar modulation during periods of changing solar activity. These exceptional measurements span nearly two decades, providing an opportunity for improved numerical modeling of the solar modulation of galactic cosmic rays across a wide range of rigidity at Earth. In this study, a three-dimensional drift model will be used to calculate theoretical spectra comparable to the observed spectra during the solar cycle 24 minimum period of 2006-2012. This modeling will be based on intrinsic parameters derived by comparing model computations to data already collected by the spacecraft. The model will be used to compute global spectra and, at lower energies (e.g., 1 GeV), to study time-dependent modulation. This time-dependent modulation, compatible with PAMELA and AMS02, has been successfully computed before. In this project, the same will be tested for the HEPD01 data set at lower energies.
