Simulation of Particle Diffusion in Magnetic Field and Stochastic Electrostatic Field
-
Abstract
The evolution of the transverse turbulent diffusion of charged particles is given by particle simulation. The simulated relative diffusion, first, rises rapidly as tα (α > 3). Then it oscillates obviously and increases slowly in an average value. Finally, it tends asymptotically to the relative diffusion in a spatially uncorrelated stochastic field(white noise). The simulated results are quite different from previous analytic theorly.
