A small-sized X-ray tube with a carbon nanotube planar field electron emitter has been manufactured and tested. Field electron emitter was grown by the chemical vapor deposition (CVD) method on a nickel substrate. During long time tests (more than 50 hours) the X-ray tube has demonstrated stable characteristics of the emitter current in the dc mode. Relative emission current fluctuations were about 0.3% at the emitter emission current equal to 550 µA.
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.
