Abstract

The GTsimulation package was developed to simulate cosmic ray propagation across various regions in space. To validate its performance, we applied it to simulate cosmic ray propagation within the magnetosphere, focusing on estimating geomagnetic cutoff energies. Using particle tracing in the IGRF-13 magnetic field model, we generated geomagnetic cutoff rigidity penumbra diagrams. These diagrams show strong structural consistency with the results of Smart and Shea, confirming the reliability of GTsimulation.
