Scientific paper

Solar energetic particles are highly anisotropic, so it is necessary to use an anisotropic equation to study their transport. The simulations of charged particle orbits in the Parker field with model turbulence will be used to study the properties of the magnetic focussing effect, adiabatic cooling, and diffusive transport in pitch angle distribution of solar energetic particles. A derived formula will be shown for the adiabatic cooling effect of particles with an anisotropic distribution. The time profile of particles' pitch angle will be obtained from the numerical computations in order to study the magnetic focussing effect and the particle pitch angle diffusive transport due to turbulence. The time profile of particle momentum will also be obtained from the numerical simulations to study the adiabatic cooling effect; and it will be compared with analytic formulae of the adiabatic cooling rate. This work is partly supported by NSF SHINE Grant 0203252 and NASA Grant NAG5-13514.
