A new CW electron accelerator with a single compact rf cavity, the rhodotron, has been
applied widely in many fields of industrial irradiation. the paper focuses on dynamics
characteristics of the rhodotron. the longitudinal and transverse dynamics simulations have
been performed with the Parmela code. in this paper, synchronous condition of beam
acceleration is deduced and the process of longitudinal phase capture is also studied. The
problem that bulks overlap each other in the center of the RF cavity under the CW mode is …
