Contribution
It provides a detailed numerical analysis of GCR proton transport in a mixed magnetic field, highlighting the energy dependence of diffusion anisotropy.
Findings
Transport anisotropy increases as energy decreases
Diffusion tensor components depend on particle energy
Magnetic field composition influences cosmic ray propagation
Abstract
The paper numerically investigates the propagation of galactic cosmic rays in a model magnetic field, which is a composition of an isotropic turbulent field with the Kolmogorov turbulence spectrum and a regular constant field. The dependence of the diffusion tensor components on the particle energy is studied. It is shown that the transport anisotropy increases with decreasing energy.
