Abstract
Due to the special working conditions of the SFC extraction deflector, the breakdown of the deflector is a serious problem. Based on the electromagnetic field calculations and the analysis of electrons and ions in the field, the breakdown mechanism was investigated. The calculated results about the electron hitting spots on the liners are consistent with the observed ones in the operation. At last, an improvement method of the deflector is suggested by using aluminum cathode and combined liners
