Description
Magnetic reconnection in realistically turbulent astrophysical environments does not depend on electric conductivity of plasma, but instead is controlled by the degree of turbulent stochasticity of magnetic field lines. Such a reconnection can induce the first order Fermi acceleration of energetic particles. I will show that this acceleration is different in 2D and 3D reconnection with 3D reconnection being more efficient in the particle acceleration. I shall discuss the importance of plasma effect both for magnetic reconnection and for particle acceleration.
