[PEM17-18] Cosmic ray transport in a turbulence field

*Tohru Hada1 (1.Earth System Science and Technology, Interdisciplinary Graduate School of Engineering Sciences, Kyushu University)

Keywords:cosmic rays, transport, non-gaussian process

Transport of cosmic rays (energetic particles) in a turbulence field remains to be an important issue, both from astrophysical and nonlinear science points of view. In particular, it is known that the transport in a plasma with large amplitude MHD turbulence can exhibit properties of non-gaussian statistics. In this presentation, we show some results on numerical integration of the so-called fractal diffusion/transport equation, which is known to model time evolution of such a dynamical system. Applications to the diffusive shock acceleration will also be discussed.
