Electromagnetic Particle Simulation Code PS2M for Bounded Plasmas with Conducting Walls

Abstract

A computational method for solving boundary-value problems for the Maxwell equation in the particle simulation is developed and is emlcodied in a code PS2M, which is a new Particle Simulation code in 2.5 dimensions (2 space-dimensions and 3 velocity-dimensions) for electroMagnetic plasmas. This method is formulated by introducing a double representation of the δ functions which are expanded by two independent sets of eigen functions in a system. The validity of solutions of the boundary-value problems is proved by invoking the mathematical law of Green’s functions. The high-order spline spatial interpolation was confirmed to be very useful in the simulation for electromagnetic plasmas, because its use removes the limit on the grid spacing, which has been severely limited of order of the Debye length in the conventional methods. This code, PS2M, has been used to study RF stabilization of the flute mode and ECRH.
