Description

We develop a radiation belt model by using probabilistic transport table that are calculated from test-particle simulations (GEMSIS-RBW). The parameters for the tables are L, background density constant along the field line, and chorus wave amplitude. The magnetic field is assumed to be the earth's dipole field. The two dimensional probabilistic table consists of the electron energy from 100 keV to 10 MeV and equatorial pitch angle from loss cone to 90 degrees. We have produced the probabilistic transport tables from the test-particle data sets before and after the scattering by single whistler chorus element. By referring the probabilistic transport tables, the model demonstrates the nonlinear and local scattering process. In this talk we briefly introduce the method and show the preliminary results.
