Abstract:A model of generation of the plasma supported by the operation of a microscale vacuum arc was developed, considering the phenomena in the cathode and anode spots. The nonequilibrium layers produced by cathode and anode evaporation were studied, and the electrode erosion rates as well as the plasma parameters were calculated. The calculation for 50 A showed that the plasma is dense, with a degree of ionization of about 0.1, and consists of singly charged ions. The anode temperature and erosion rate exceed these… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
