Operation of a Five-Stage 40,000-CM2-Area Insulator Stack at 158 kV/CM
Abstract
We have demonstrated operation of a 3.35m-diameter insulator stack at 158 kV/cm with no total-stack flashovers on five consecutive Z-accelerator shots. The stack consisted of five +45 -profile 5.715-cm-thick crosslinked- polystyrene (Rexoiite-1422) insulator rings, and four anodized-aluminum grading rings shaped to reduce the field at cathode triple junctions. The width of the voltage pulse at 89% of peak was 32 ns. We compare this result to a new empirical flashover relation developed from previous small-insulator experiments conducted with flat unanodized electrodes.
