Sintered tungsten wire, reservoir cathodes offer high current density operation with very long life time. The diffusion rate can be selected consistent with the current emission density. This presentation will describe the impact of this technology and present the latest test results.
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.
