An algorithm for numerical calculation of the trajectories of electrons emitted by plasma in the electron beam moving in axially symmetric electrostatic and magnetostatic fields is proposed. This algorithm is based on the technology of charged particle beam discretization by current tubes and the decomposition method of the computational domain. Field simulation and numerical solution of equations for particle motion are carried out with the use of quasi-structured grids.
