The current drainage from a plasma through approximately 0.05 cm diameter holes in Kapton H polymide film, P E P type C., and quartz microsheet placed on a probe at voltages up to 2000 volts d. c . have been determined both theoretically and experimentally. A Laplace field was used to numerically predict an upper limit for the drainage current. The measured current was less than the theoretical current for the F E P and quartz, and the two were approximately in agreement for Kapton He The measured currents were on the order of 5 microamperes with the theoretical currents on the order of 10 microamperes.
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.
