Abstract：
Usually, the RF electro-magnetic field can affect the resonant cavity in two ways. One is the heat loading to the cavity due to the RF power dissipation, and another is the Lorenz force due to the high RF surface field. In this paper, the RF electro-magnetic field effects on the Sub-harmonic Buncher 2 (SHB2) are described and some results presented and discussed. The analyses of the RF electro-magnetic field effects were performed by coupled simulations with finite difference method software-Superfish and finite element method software--ANSYS. In addition, the RF electro-magnetic field effects on the Sub-harmonic Buncher 1 (SHB1) are also described.
