Abstract:Fast acting gas valves that operate between two very different pressure environments, which may differ in several orders of magnitude, are not available commercially and, therefore, they must be specifically projected and constructed. For the TCABR impurity pellet injector, under construction, an electromagnetic valve has been built which operates for gas pressure that ranges from 20 to 40 atm at one side of the valve to 10 −9 atm at the other side. The working principle of the valve is based on the displaceme… 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.
