Abstract :
High gradient insulating technology is one of the key technologies in new type dielectric wall accelerator. Micro-stacked insulators were prepared and preliminary experiment was done in this paper. Using high temperature laminated method, two types of micro-stacked insulators were designed and fabricated. The first was fabricated from interleaved layers of brass and polyimide (PI), and the other was fabricated from stainless steel and fluorinated ethylene propylene (FEP). Surface state of insulators was observed and out-gassing characteristics in vacuum were also detected. Based on the nanosecond (10 ns/30 ns) pulsed experimental platform, the vacuum surface flashover characteristics of micro-stacked samples were tested. Micro-stacked insulators exhibited favorable vacuum surface flashover performance and the maximum flashover field strength was close to 180 kV/cm.
