Abstract:Numerical calculations of time‐dependent charge distributions are presented and compared with distributions measured on radiation‐charged electrets made of thin polymer films, which are charged and discharged in a radiation‐charged electret ionization chamber (REIC) through the application of ionizing radiation. The chamber resembles a parallel plate ionization chamber, and has a thin film of polymer covering the collector and guard‐ring electrodes. Calculations are performed by solving Laplace's equation for … 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.
