The origin and acceleration of cosmic rays in the Universe remains an open question despite more than a century after their first discovery, and it remains one of the central problems of high-energy astrophysics and astro-particle physics. Bulk of the galactic cosmic rays that form the so-called “knee” in the cosmic rays spectrum, are primarily accelerated by a Fermi-type process known as diffusive shock acceleration. This project studies particle acceleration (electrons and ions) and critically evaluate the dependence of ion acceleration and its efficiency on magnetic field obliquities.
