Description

Fermi acceleration refers to a type of motion in which charged particles are constantly reflected, most often through magnetic mirrors. Such a motion takes its name from a famous scientist, Enrico Fermi. Accelerated Fermi motion is the main mechanism for how we would describe the accelerated motion of cosmic rays. These aspects where mainly discussed by A.J. Lichtenberg and M. A. Lieberman in book: “Regular and Stochastic Motion”. Main topic was examining diffusion, helping us understand these astrophysical objects.
However, this aspect is not fully examined. Our knowledge is limited because we cannot observe cosmic rays with enough precision, because of that aspect of diffusion remains uncertain.
This research will be using computational methods, like MATLAB, helping us understand this process better.
While researching this topic, there has been spotted anomalous diffusion, also some interesting observations concerning cosmic rays and it shows how initial parameters could change our whole perception of a process.
Significanse of this research is studying the behaviour of cosmic rays, which could be explaining a lot of gaps in science.

Keywords: Diffusion, Cosmic rays, accelerated Fermi motion.
