Abstract：
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 solved by adjusting The parameters of bending magnets. the process that the major traverse focusing is achieved using the bending magnets is analyzed carefully.It is generalized how the space charge effect and the variation of initial parameters impact on transverse beam stability. the distribution of beam losing power is calculated for the radiation protection of this machine. the simulation results agree with The operational parameters of the Rhodotron's prototype, which confirm the research method's feasibility.
