Physical design of compact continuous wave electron accelerator for irradiation

To meet the increasing demand for domestic industrial electron accelerators, a new type of compact continuous wave (CW) electron accelerator which works at 180 MHz is proposed. It accelerates the electron beam within the cavity and performs successive acceleration by several bending magnets located outside the cavity. The resonant cavity design is optimized by CST and the particle dynamics is simulated by Parmela. The longitudinal stability and the transverse focusing of electron beams are also analyzed and verified by beam simulation. The result shows that this accelerator can accelerate continuous beams at the output power of 100 kW with a beam energy of 9 MeV．
