Stationary and transient beam dynamics simulation results comparison for travelling wave electron LINAC with beam loading

The methods of beam dynamic simulation taking into account the beam loading effect are discussed in this paper. It is one of main problems limiting the beam current. The simulation methods for stationary case were described in the paper. The test simulations will discussed for transient mode and stationary case in this paper. The beam dynamics simulation will done using BEAMDULAC-BL and BEAMDULAC-BLNS. These codes were computed to study the beam dynamics in accelerators working on a traveling wave in stationary and transient cases respectively. The results of simulations were compared for both cases.
