摘要：

Experimental studies of the vacuum surface flashover of high gradient insulators (HGI) made of Kapton and stainless steel are introduced in this paper. The HGI samples are all 60 mm in diameter and 8 mm in height. The highest peak gradient held under the 120 ns (FWHM) voltage pulse is nearly 13 MV/m. Studies about the testing methods and the thickness ratio between the insulator and the metal are also discussed in this paper. Moreover, comparison of the insulate strength between the HGI samples and the insulator made of conventional materials are presented. The result indicates that the performance of the HGI samples is obvious better than the conventional insulator made of pure Kapton.
