Results of modeling of a high-current relativistic beam by the finite-difference method are compared with results obtained for a beam with the same parameters using the well-known KARAT code, which is based on the large-particle method. These two methods give similar results, which justifies the use of the finite-difference method for the numerical solution of the equations of motion describing the motion of the beam in its own and an external electromagnetic field.
