Transition of Window Breakdown from the Vacuum Multipactor Discharge to the Collisional RF PlasmH.C. Kim, J. P. Verboncoeur, G Edmiston, A.A. Neuter, Y G J Lau, R. M. Gilgenbach2006 IEEE International Vacuum Electronics…2006In high-power microwave systems, we investigate the transition of breakdown from single surface vacuum multipactor discharge to collisional rf plasma in argon. As the gas pressure increases,… (More)
