The twodimensional simulation model

Saito et al. (2003) used two-dimensional, fully electromagnetic, and relativistic 'particle-in-cell' code of Buneman (M1993). The lengths of the system are Lx = 4000A and Ly = 64 A, where A is the grid size. The periodic boundary conditions are imposed in both x and y directions. There are 60 electron-positron pairs in a cell uniformly in whole system. The background magnetic field and counter velocity are parallel, and their direction has been used to define the x-axis. To set the counter-streaming plasma Saito et al. (2003) divided all particles into two components. Both electrons and positrons in the left hand side have the velocity 0.5c, and in the right hand side have the velocity -0.5c. The other parameters are as follows: the simulation time step is copet = 0.05, where ct)pe is electron plasma frequency; the

Debye length and skin depth are 1A and 10 A, respectively; both the electron and positron thermal velocities are 0.1c. The parameters associated with the background magnetic field Bo are listed in Table 4.28.1.
