Results of numerical simulation of electron dynamics in a non-homogeneous disk-loaded waveguide which is used in the S-band linac with average power of an accelerated beam of 10 kW are presented. Two approaches taking into account the self-fields of beam radiation are considered: the first method, the estimative one, based on the power diffusion equation; the second, the full-scale one, based on self-consistent equations of field excitation and particles motion. The self-consistent approach showed the presence of substantial phase slipping of particles in the homogeneous part of the rf structure, conditioned by the reactive beam loading. © 2012 by Begell House, Inc..
