Cosmic Rays In The Solar System

摘要

Calculations of cosmic-ray propagation through the heliosphere, in the terrestrialatmosphere using a combination of a modified version of the adjoint Monte Carlo code,ATROPOS, and a suitably modified version of the deterministic transport code, PLOTINUS.ATROPOS solves the Parker heliospheric transport code in one and two dimensions in a 3-dimensional heliosphere and provides cosmic-ray spectra to be used by PLOTINUS to determinethe radiation effects of interest. Other cosmic-ray properties, such as the deceleration time (relatedto the so-called deceleration potential) and the angular distribution of cosmic rays at earth orbitwill also be described.
