Abstract:When electrons strike a surface with sufficient velocity, secondary electrons may be emitted by it, some or all of which may be collected by a suitable electrode having a higher potential than the emitting surface. (“Secondary electrons” are here taken to mean all electrons which leave the surface, whether reflected, rediffused, or actually emitted by the surface.) In the work to be described, a triode is considered, in which the anode receives electrons from the cathode, and emits secondary electrons which ar… Show more
In some computations on transmission line measurements it was found that a table of (1/x) tan x was necessary and this was computed for the following radian arguments:
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.
