  2. The diffusion coefficient in momentum space

  3. Conclusions • Particle acceleration by large scale EF can be efficient for a medium of sufficiently high magnetic helicity • The results can be useful for description of particle acceleration in astrophysical objects ( solar flares, supernova remnants, galactic nuclei, … )
