Abstract

Magnetic reconnection is a potential mechanism for charged particle acceleration in astrophysical and space plasmas, especially in solar flares, which are rich sources of highly energetic particles. "Torsional fan reconnection" is one type of model for steady-state 3D null point reconnec- tion. In this study, we investigate proton acceleration with input parameters for the solar corona in the presence of the magnetic and electric fields associated with torsional fan re- connection. By randomly injecting a population of 10,000 protons as test particles in the vicinity of a null point, we show that two symmetric jets of accelerated protons with relativistic energies are generated along the spine axis above and below the fan plane. These jets comprise almost all of the population with average kinetic energy on the order of a few MeV. Also, the details of the energy spectra are dis- cussed.
