Its target is to demonstrate and validate the performance of a novel C12A7:e- electride material as electron emitter instead of traditional thermionic emitters such as lanthanum hexaboride, LaB6, or barium oxide, BaO. In this study, a fair comparison between LaB6 and C12A7:e- samples was performed both addressing pure material characterization parameters as well as comparing performance as cathodes under different architectures and operational conditions. In this case, a current/cathode power ratio around 3 mA/W was obtained when using the C12A7:e- sample in a plasma environment with Ar, which is approximately one order of magnitude higher compared to the LaB6 sample.engAttribution 4.0 Internationalhttps://creativecommons.org/licenses/by/4.0/C12A7electric propulsionLaB6cathodeinfo:eu-repo/semantics/conferenceObject10.1088/1757-899X/1226/1/012093info:eu-repo/semantics/openAccess
