کلیدواژه‌ها	Cosmic Ray Propagation, Simulation, Fractal Medium
چکیده	Cosmic rays propagation within the Galaxy is simulated considering a fractal-like distribution of matter and magnetic fields. In such an anomalous diffusion process, thesources of ultra-high energy particles were considered to be galactic pulsars. The coordinateand birth times of sources were chosen from SN and pulsar catalogues. From these sources theprimary spectrum of cosmic rays (H, He, CNO, Ne-Si, Fe) in energy range EeV and above werereproduced. The resulted spectrum is used to discuss about the change in cosmic ray sourcesform Galactic to Extragalactic.
