Abstract :
The authors discuss the electrical and mechanical requirements for vacuum insulators in high peak power generators. To increase the lifetime of these insulators, they have developed a coating called Dendresist. This coating has extended the insulator lifetime on the PITHON, DM2, CASINO, and Double-EAGLE pulsed power generators. They describe its development, and compare its electrical and mechanical strength to that of other candidate coatings and materials used for vacuum insulators. They discuss the mechanism for discharges through the bulk of the insulator ("worm-holes"), and how to eliminate these failures using thicker insulating rings.
