Numerical Simulation of Electromagnetic Fields Generation in the Cylindrical Cavity by Relativistic Electron Flux
Abstract:
The experiment, which is in the axial-symmetric relativistic electron flux injecting from the end face into the cylindrical chamber (material – Fe) filled with the air, is considered. The mathematical model contains the 2-D non-stationary Maxwell equations in cylindrical coordinate system, the equations for computing the air conductivity in the chamber and the particle simulation algorithm for the relativistic electron flux. For integrating the Maxwell equations the quasianalitic interpolation technique is used. The computation of the current density that is realized in the particle simulation algorithm is based on the charge conservation in grid cells. The technique of the parallel computations at multiprocessor with distributed memory is proposed. This technique is different from the geometric method and uses the fact that the particle simulation algorithm occupies the basic time of computations.
