Study on Breakdown of SFC Extraction Deflector

摘要

摘要: 根据SFC引出静电偏转板的特殊工作环境和运行中发生的现象，对其高压放电机理进行了深入的研究和大量的电磁场计算。计算结果表明，在电场和磁场的共同作用下，盖板损伤的发生部位与实际运行中的打火痕迹完全符合。最后阐述了SFC引出偏转板的高压放电过程，并对其改进措施进行了研究。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
