The operation of a hollow-anode (HA) electron source with a biased output grid and an incorporated ferroelectric plasma source (FPS) in a diode powered by a 200 kV, 400 ns pulse is described. It was found that the FPS allows reliable ignition and sustaining of the HA discharge with current amplitude 11.2 M a n d pulse duration <2x s a t N, gas pressure of (l-3)x104 Torr. Parameters of the hollow-anode plasma were studied by different electrical, optical and spectroscopic diagnostics. It was found that the pla…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
