A numerical calculation of beams of charged particles by iterations over subregions
An algorithm for iterations over subregions is constructed for calculating non-relativistic two-dimensional electrostatic beams of space-charge limited charged particles. The emission current density is determined from the distribution of the electric-field strength at the “collector” using antiparaxial expansions, which describe the region near the emitter.
