| Magnetic reconnection is known as an essential process to convert stored energy of magnetic field into the kinetic, thermal energy of plasma and the acceleration of charged particles in astrophysical and space plasmas. In this paper, we investigate some features of test particle acceleration during spine reconnection with an asymmetric current sheet. To do so, we study first the acceleration features of a test-particle and then discuss acceleration of a randomly injected population of 10,000 protons in the vicinity of a null point with input parameters for the solar corona. It is shown that protons are accelerated up to tens of keV and even higher kinetic energies, either along the spine axis or on the fan surface along specified lines. Also, we discuss the variation of energy spectra for different strengths of the electric and magnetic field amplitudes. | ||
