A 2D Stochastic Simulation of Galactic Cosmic Rays Transport in the Heliosphere
Abstract
We present a new code to numerically simulate the transport of galactic cosmic rays in a 2D axisymmetric heliosphere. The model solves the transport equation by sto chastic simulation techniques, tracing trajectories of test particles in a guiding center approximation. It includes such basic modulation mechanisms as diffusion, convection and adiabatic cooling. We present the first results from this model and compare the effects of the different modulation mechanisms in the model.
